Technology, Connected - America Has One Lithium Mine. Clean Energy Wants 117 More

Episode Date: May 23, 2026

Jennifer Dunn, professor of chemical engineering at Northwestern University, joins Thinking on Paper to explain how lithium and copper mining affect water, ecosystems, local communities and the wider ...energy transition.Lithium and copper are essential to electric vehicles, grid storage, renewable energy, drones and data centres. But the environmental consequences of extracting these minerals vary sharply depending on the mine, location, technology and supply chain.Life cycle assessment offers a way to compare those impacts across different forms of production, from lithium brines and hard-rock mining to copper extraction, refining and recycling.In this episode, we discuss:The environmental impact of lithium miningHow lithium brine mining compares with hard-rock lithium miningWhy copper demand is risingHow mining affects water use and local water stressThe risks of pollution, biodiversity loss and mining wasteHow life cycle assessment compares mines and supply chainsWhy local conditions matter more than global averagesThe role of mine permitting in the energy transitionWhether recycling can reduce demand for new miningHow battery supply chains shift environmental costs between regionsWhat responsible critical-mineral production should look likeJennifer explains why no single measure can capture the full impact of a mine. Carbon emissions matter, but so do water availability, land use, waste, local ecology and the distribution of costs and benefits.This conversation examines whether clean energy can scale without transferring environmental harm from fossil-fuel systems to the communities that supply lithium, copper and other critical minerals.--Thinking on Paper is a technology podcast about AI, Space, quantum computing, science, and the systems shaping the future. 🏠 Buy us a beer on Substack🎧 Take us with you on Spotify🎧 Remember steve jobs on APPLE📺 Get the clips and outtakes on Instagram --Chapters(00:00) Disruptors & Curious Minds(02:10) The Demand for Copper and Lithium(02:57) Environmental Impact of Mining(05:59) Water Consumption and Mining Methods(08:30) Community Concerns and Local Impact(11:29) Recycling and Wastewater Mining(14:04) Life Cycle Assessments in Mining(27:06) Understanding Emissions in Mining(29:45) Life Cycle Assessment: A Comparative Approach(34:05) Stakeholder Perspectives on Mining Impacts(37:42) Technology and Transparency in Mining(42:42) Consumer Awareness and Ethical Sourcing(48:55) Challenges in Quantifying Social Impacts

Starting point is 00:00:00 Here's some data I want you to carry with you in your head as you listen today, as you think on paper with us today. There are approximately 700 copper mines in the world spread across 40 countries. In 2010, the world mined about 16 million tonnes by 2024, 23 million tonnes. And then lithium. There are about 25 lithium mines in the world, Australia, Chile, Bolivia, Argentina, our friends in China. Australia alone supplies more than a third of the world's lithium. In 2010, the world mined 28,000 tonnes approximately.
Starting point is 00:00:35 In 2024, 240,000 tonnes. So today, we're asking a few questions. What is the environmental impact of getting lithium and copper out of the ground? How are we measuring that environmental impact? And as the thirst for EVs and the electrification of everything, just increases, why does it matter so much? Today's guest is Jennifer Dunn. She's a professor of chemical engineering
Starting point is 00:01:01 at Northwestern University, and she spent her career trying to answer that very question. So welcome to the show, Jennifer, thank you for thinking on paper with us today. Yeah, thanks for having me. It's a lot of minds, it's a lot of demand. Surely all those minds are equal. They're all measured the impact.
Starting point is 00:01:22 We know what's happening in each and every one of these minds. We know what the damage is. We know what the impact is. It's all documented and recorded, surely, isn't it? Actually, it's really not. And it's really hard to figure out we've been working towards that. And we've been kind of learning about the different ways that different minds are being held accountable or, you know, choosing to sign up for reporting some of their burdens. It's interesting to me, too, I think just the level of removal, the stages in between,
Starting point is 00:01:54 the mineral itself that we're pulling out of the ground to the humans eventually using the piece of technology that requires it. How challenging is that disconnect to generate awareness on some of the things that you're trying to bring forth? I think what's interesting is that the minerals that we use, like copper and lithium in devices, like our laptops, our electric vehicles and grid storage, you know, I know I'm not supposed to talk about a certain topic, so I won't mention what we might use grid storage for, but, you know, all those energy storage devices, very few of them, for example, are manufactured in the U.S. or even Europe. Most of them are manufactured in Asia.
Starting point is 00:02:37 And so, you know, you mentioned some of the leading suppliers of these minerals as Australia and Chile. While I'm aware that, for example, the Chilean government would like to do more on the value chain once a mineral is mined in their nation. to do some value add and do some manufacturing. That's not what's happening today. Today, much of the lithium and the copper that come out of Chile and other nations heads to China for use of manufacturing processes.
Starting point is 00:03:03 Then, you know, the products of that manufacturing are sent around the world. So whether that's laptops, phones, or what's in an EV, yeah, that's largely being manufactured in Asia. And then coming, I'm in the U.S., so coming over to us on ocean-going vessels and it's, yeah, we're using it here. So there are, of course, efforts in the U.S. to expand, for example, lithium-iron battery manufacturing and other technologies that use minerals. Like, we want to also, like, onshore those manufacturing processes here in the U.S.,
Starting point is 00:03:33 but as of today, it's not the dominant place where the manufacturing steps happen. This conversation started initially about rare earths, and they get all of the press, they get all of the Hollywood. It's all about the rare earths. And I think it's because they're called rare earths, but lithium and copper, and these other minerals are equally important, why don't they get the attention that the rare earths get? You know, it's a really interesting question, and I think a lot of it has to do with China's having the lion's share of rare earth supply chain from start to finish, from mining, these minerals
Starting point is 00:04:12 out of the ground to manufacturing with them. And in a way that's like very sort of from an energy security from even a defense aspect because we use a lot of rare earths and defense technologies that's concerning. And so I think nations like the U.S. are interested in finding ways to improve the security of the rare earth supply chain and relying less on a country like China for those minerals. And so I think that is one reason why there's such a pressing need to shift the supply chain for those minerals, whereas, you know, as you mentioned with lithium and copper, We're primarily looking at nations like Chile and Australia where we have, you know, sort of more stable relationships with those nations. And so perhaps the supply chain security is a little bit less of an issue.
Starting point is 00:05:02 But the increase in demand is quite large over time, like over through 2050 or so. And so then the issue is more like we're going to need a lot of this and less about like we're really worried that we're going to get cut off from the supply of these minerals. Jeremy, Spot Quiz. How many lithium mines are there in the United States of America? I think they just dusted off one, didn't they? Wasn't there like, isn't there one? Yeah? Did I get it right?
Starting point is 00:05:29 Yeah, there's one operating mine. And one of the students in my group, we are getting, I hope, very close to getting a new paper out on planned expansion of lithium mining in the United States and what that would mean for water stress, especially as the climate changes. And so through that work, she was like, yeah, there's only one that operates right now. But in her analysis, she looked at 117 planned mines that she considered. I think she boiled it down the analysis to around 50 or 60 of those for the actual modeling work that she did. Because, you know, many mines are in general, many types of facilities are planned, but they don't come into existence. She had some criteria for filtering those down. Where is it? Where is the one?
Starting point is 00:06:16 Nevada. It's in Nevada. How does it compare on a global scale in terms of size and production? Oh, we in the U.S., we produce a very small amount of the global share of lithium. We don't even make the top nine. Like, yeah, so it's tiny. And I think that that's, you know, but at the same time, if you read reports out of the International Renewable Energy Association, in arena, like demand for lithium through 2050 is projected to be 2,120% increase.
Starting point is 00:06:50 And so it's just huge. And so we, you know, hope to meet a large portion of that through efforts like recycling. But it's sort of unavoidable that globally will need to increase the production of lithium from mines. And I think the U.S. now has decided like this is a real priority for the nation. Is that been driven by EVs and other sustainable tech? What else is in that picture? Drones. That's a lot of drones, like 2,000 percent increases.
Starting point is 00:07:25 That's a lot of drones. Yes, I mean, it's EVs, and this is global, so that that demand number is not just for the U.S. But, I mean, overwhelmingly, that demand is fueled by energy storage, whether that's in a laptop, a cell phone, or an EV. or a grid-scale battery, which, you know, as we deploy more and more renewables for whatever purpose, of course, the energy storage piece always comes up as a part of how to make renewable energy more reliable, more sort of available to us, even as we always say, when the sun isn't shining, and wind isn't blowing. So, yeah, so I think that it's really that demand for energy storage
Starting point is 00:08:05 that is pushing that demand for lithium higher and higher. There are other much smaller uses for lithium-like in lubricants and somewhat in medicine, but those are not the reason why this is skyrocketing. Is it fair to say that your work is looking at what the impact of extracting these elements out of the ground is doing? And can we talk about like, does that make the impact of the energy transition to cleaner energy more challenging, more difficult, more maybe wash out because we're not doing the right stuff on the front end? Yeah, I mean, from analysis we've done and others have done, you know, when you look at the per mile greenhouse gas emissions of an electric vehicle versus a conventional gasoline car, the electric vehicle wins. It has fewer emissions per mile. So if your
Starting point is 00:08:56 lens is primarily focused on we need to decarbonize transportation, then of course we're going to go with the EVs, right? You know, climate change is probably, in my opinion, the most pressing challenge we're going to face the society. And it's a global problem. But then, you know, when you start to think about these supply chain issues around supplying EVs and these other needs, we have for copper and lithium, which we can talk about other demand besides just the batteries themselves, and you start to think about what's the impact of acquiring these elements or these minerals from the ground. It's pretty substantial. And what turns, what is a global, problem of climate change turns into a really local problem for individual communities where mining
Starting point is 00:09:43 can deplete water supplies. So 16% of the world's mines exist today in water scarce areas. And when I mentioned this study that my student and I are on the cusp of getting out in the world, there's not enough water to meet the demand that these mines will have, especially in the southwest of the U.S. Nevada, for example. And it's It's interesting. Okay, so water consumption is an issue. Water pollution is also an issue. And so communities face this risk of having, you know,
Starting point is 00:10:21 just in general, additional emissions to water from mines that happened. So in the U.S., you'd get like a mine would get a permit, right? And they would be allowed some level of pollutant emissions to water. But that is now that that baseline is zero, that that mine doesn't exist. And so inevitably there will be just more pollution because as mining expands in the U.S. And so then the question is, well, what's the impact of that? And of course, this is when we look, we've looked at this Atlas. It's called the Environmental Justice Atlas about, I mean, did this for globally.
Starting point is 00:10:55 We looked at what our communities worried about as mining. It's actually not even as mining expands. It's an existing mining. And we looked specifically at minerals that are part of the energy transatlantic. supply chain. And a lot of it is water. They're worried about just, again, this water consumption and then water pollution because, of course, people use water for all sorts of things to irrigate crops, just to drink, and for many other uses. And so whether it's depleted because there's less of it or it's depleted because now it's not drinkable anymore or requires so much more
Starting point is 00:11:28 investment to clean up the water before you can drink it, that's a problem for communities. We also see communities really worried about changes in biodiversity, which, you know, we are, in my opinion, I'm a chemical engineer, so biodiversity science is, of course, not my wheelhouse. But I think just as scientific community, we're first starting to understand what do we lose when biodiversity declines in terms of ecosystem services that help keep us healthy and keep us well and help the environment function as it should. And so I think that, you know, we don't fully understand the impacts of mines on biodiversity, but this is something that communities are really worried about. Could we just go back to the water issue? So copper mining notoriously water intensive. I've got here, like 70 to 100 cubic meters of water per ton of copper.
Starting point is 00:12:22 Some information, so chili using 30% desalinated water. But I'm interested in the lithium mine. because there's two types of lithium mining, like lithium is found in two deposits. You have hard rock deposits and you have brine deposits. Yes. And how it is mined is very different between those two sources and the water consumption in each of those is very different. Could you walk us through the difference between hard rock and brine deposits for lithium and then how the water impact changes depending on which method?
Starting point is 00:12:57 Yes. So I had to log back into my computer. Your apologies for that. But yes, we did, as part of this paper I was mentioning, we looked at the water consumption for these different types of acquiring lithium or different methods of acquiring lithium. And the literature has a pretty wide range for some of these methods. So brine, on the median number we pulled for just brine extraction,
Starting point is 00:13:21 was around 200 meters cubed per ton of lithium carbonate. And then when you move to something like requiring brine from geothermal, the data is scarcer. So for the lithium brine extraction, we have to look at 22 studies to try and pull those numbers out. For the geothermal brine extraction, there were only six that we could find at the time in the public domain. And that was like much higher. It was closer to 300. But hard rock for lithium is actually a much lower number. but again, we're a little data limited.
Starting point is 00:13:55 There were only three studies that we could find in the public domain that reported these numbers, and that was closer to, like, let's say, 80 meters cubed per ton. So actually, hard rock is not, like, water consumption for hard rock lithium mining from what we can tell based on what's available to us is not necessarily more concerning from a water consumption standpoint than the brine extraction methods. So that's somewhat reassuring.
Starting point is 00:14:27 From an energy consumption standpoint, I've had the very good fortune of being able to visit the SQM facility in the Atacama Desert in Chile. And, you know, it's a lot of kind of like waiting for the water to evaporate. And so as from an energy perspective, it's not that energy intensive. And I remember when I was first starting to look at,
Starting point is 00:14:51 at these questions back, it was about 2010, my first started thinking about these things. I remember doing some of this math around the water consumption, an energy consumption, sorry, of brine extraction. And I thought, this is really not a big deal. I mean, I was just the very beginning of this journey. And I thought, well, you know, from a water, sorry, for an energy perspective,
Starting point is 00:15:14 extracting brine is like not a big deal. And I remember even back then, they're like, you know, listening to the radio and news stories, people were already starting to talk about some of these issues. And I was like, ah, the lithium is not a big deal. But I was not at all at that point in time focused on water and thinking about the impacts on water. On the research of the brine deposits, the water table has been decreased because they're using so much water to dilute the lithium, that they're actually lowering the water table, which obviously has secondary effects all over the water basis.
Starting point is 00:15:46 It does. And this is a really an interesting point. We had a workshop in Chile about a year ago, maybe a year and a half ago. And we had a group of indigenous community leaders from the Atacama Desert speak about some research they had done with the university in that region that really showed the water table declining. This was of great concern to them. But when you talk with some of the lithium companies, they say this is not consistent with what they are finding. They are not finding this. And it's really interesting because, for example, SQM has real-time water table measurements that you can go and look at on the Internet.
Starting point is 00:16:28 And so, you know, these are efforts at transparency and communicating with the community about the impacts of their mind. And to me, that's actually one of the very few examples of where communities have some real-time access or very near real-time access to some of these data about water consumption effects. So that is very admirable. But it was interesting to hear from these community leaders that this remained a big concern and that their science was showing a little bit of a different result. And so I think this will continue to be an ongoing debate. And, yeah, I think that just to bring the lens back to the U.S. for a second,
Starting point is 00:17:04 you know, there is a lot of local resistance to expanding mining. There's these dueling narratives of more jobs versus these impacts on the environment. And there's been an effort in the U.S. to try and speed up the permitting process because of these kind of delays. So in the U.S., it can take 29 years to get a mine up and running. 29 years. Yes. The permitting process is really involved. And there's a lot of legal action, right?
Starting point is 00:17:37 So people are suing to try to get mines stopped. And this was what happened in Minnesota for this mine. It was a copper nickel mine that's been proposed, and it's been in a holding pattern for quite some time. And just recently, the Trump administration lifted mining restrictions on the boundary waters in Minnesota, which is not right where that mine is proposed. But Minnesota in general and Michigan are part of the copper range, the iron range here in the U.S., and so this is like a region that's really kind of under the
Starting point is 00:18:14 microscope for additional copper mining in addition to, of course, Arizona is another sort of big area for the U.S. for mining copper, where existing copper mines are. So, you know, there's this concern around community engagement and just communities have the power to stop or slow these processes. And so when we think, about, you know, if we need these minerals for various applications and we think it's important to build new mines, we have to think about how do we help communities understand these impacts and, you know, it's always more expensive to adopt more pollution control. And it's a global market, right? So you're competing as a mine, you're competing on a global market. And if the U.S.
Starting point is 00:19:01 legislators are saying you need to, or a permitting process results in more stringent pollution control, your per ton numbers, a dollars per ton, are going to go up, but you might not get the chance to open your mind. You might need to slow opening if you're not satisfying the concerns of communities and local regulators around things like water pollution and water consumption. So that's a tradeoff that I think we don't really know enough about. Like, as an academic, I'm very interested in that tradeoff. I don't ever need to open a mind. So I'm not concerned about making money. I'm just really interested in that tradeoff and what it means for like a secure supply chain,
Starting point is 00:19:43 a supply chain that helps us advance the energy transition without, you know, doing as much as we can to limit any sacrifices of local community. I read somewhere, I can't remember if it was in one of your studies or in my wide cast of research on the subject, that there is potential to mine wastewater. Like there's potential minerals within wastewater that we could take advantage of that we're not currently. And how does that compare to like how we evaluate the mining process in general? So it's true. And some estimate that in the U.S. alone, if we were to recover minerals from waste streams from mines that have closed and mines that are operating, we could meet a lot of our demand for minerals.
Starting point is 00:20:29 I think the hard part is that oftentimes minerals in waste streams are very dilute. So like their concentration is really low. And so, you know, it's why they weren't recovered in the first place was that the economics are more challenging when you have these dilute or low concentrations. But now the market has definitely changed, right? And so I have an economist friend who says, like, we will never, ever, never run out of these minerals because if the demand is high enough, we can accommodate higher costs for recovering these minerals from,
Starting point is 00:21:02 from laptops and or from mining waste streams. And to me, that is a really exciting possibility. And I get to do some work with collaborators who are interested in developing technologies to do just that, whether they're using biology, like proteins that are really selective, in extracting specific minerals. You know, there's also kind of like a super, that they're in of other things that you might not want. And so selectively recovering what you're
Starting point is 00:21:32 interested in in these waste streams is really interesting. So, you know, so as a chemical engineer, it's like, okay, well, we could use sort of like bio-based or bio-inspired methods. We could use adsorbents that focus more on chemistry and instead of like more chemical or maybe more traditional chemical engineering approaches to doing that. There's people interested in using electrochemical based methods to do that. So, and this is a really active. research space right now in the U.S. So I'm sure you're aware that the U.S. government has really dramatically sort of decreased the amount of federal funding for science research in our country.
Starting point is 00:22:08 But this area of recovering minerals from waste remains an active area where the need, it's so obvious that we need to work on this, that it is an area you can still obtain funding. And so that's like pretty kind of a renaissance of research in this space. Beyond the wastewater, what about the recycling in general of existing technology, which is full of lithium and copper? Yes. So, you know, I heard this really interesting talk last year at the American Institute of Chemical Engineers convention where this was at Michigan Tech up in the Upper Peninsula of Michigan. And they had actually gone to a landfill and extracted like e-waste, basically. And they were, I think the mineral they were trying to get back was nickel. And they were like, this is really hard. So, you know, when we think about like urban mining and landfill mining, it's a really interesting topic. But again, like the economics and the technical challenges are pretty substantial. And it's just kind of, you know, messy. And so, but I, nonetheless, I'm really excited about work like that. And so that's like getting it back out of a landfill. But of course, I'm sitting here surrounded by multiple,
Starting point is 00:23:25 electronic devices that will expire in the next, I don't know, at most five years. And so, like, my library has a program where I can go drop off my e-waste. And, but nonetheless, this is also still an area where the economics are a little bit challenging and there's a need for technology development. And this is still, the federal government's also funding research in this space. And there are lots of startups trying to make this a reality. And I think it will become a reality. I think it does face some of the challenges that plastics recycling faces in terms of like the distributed nature of the feed stream. So, you know, at a mine, like, everything's like right there. But in, in this world of getting minerals back from spent electronics, you just need to rely on people
Starting point is 00:24:09 to not keep everything in their drawer, like their literal drawers in their house, bring it to a recycling center. And of course, the other challenge is that the battery chemistry is changing over time. So companies are trying to maybe limit cobalt, for example, in energy storage devices, regardless if it's an EV or a laptop, because of the cost and also some of the environmental and, like, social concerns around cobalts. But cobalt is like a high-value mineral, and it might be a reason why you want to get, why you want to recycle in the first place. Whereas lithium historically has had lower costs. So a battery that has lithium-iron phosphate chemistry, for example, there's not necessarily a super high value component of that battery.
Starting point is 00:24:56 And so that's another project we're working on is really thinking about what makes the economics work for recycling with the ion phosphate batteries where Tesla is kind of going, right? Or they've already gone. So yes, like spent device and spent battery recycling is going to be a really important stream. I think we're still working on the engineering of those systems and we're still thinking about the social engineering of recovering these devices from the broader.
Starting point is 00:25:23 public. And even getting them back out of landfels. Yeah. Well, get all those old Teslers, they'll be starting to fall apart by now. And there must be those first first Tesla. Where did Tesla get there, lithium from China, I guess? We've got a mine. So it sounds like, okay, there's a lot going on with recycling, but such is the demand.
Starting point is 00:25:45 We have to mine. I was very surprised when you said there's only one mine in America, but there was potentially 150. But then you said it takes 29 years to get a mine open. maybe that's one of the reasons. But we have to mine. So LCA's, Jeremy, over to you and the LCA question. Well, I think when we started this conversation, Jennifer,
Starting point is 00:26:02 you mentioned creating a common framework or language to assess the impact on the front end of mining some of these things. So talk us through what LCA's are, why they're important, what you're doing with them and your work, and what people need to know about them. Yeah, so life cycle assessments is basically a methodology. that can be applied to any system of study. We're interested in applying them to mining. And the way that life cycle assessments work is that an analyst or a researcher
Starting point is 00:26:34 will think about for every step of a mine's life, even from back to exploration and all the way through closure and then maintenance, post-closure, which can be, you know, decades, what is every unit of energy, every unit of water, and various chemicals that are consumed to produce all the minerals that mine will generate over the course of its lifetime. And we also want to think about over the course of its lifetime, how much does the mine, how many pollutants does the mine emit? So we're concerned about things like dust. And air pollutants like, even like Knox, for example, because mines combust diesel fuel in mining equipment,
Starting point is 00:27:17 and that does contribute to air pollution like Knox, volatile organic compounds, and so on. but also emissions to water, whether that's minerals or various chemicals that are used or sulfates is a big area of concern in Minnesota, for example. So we try to sit down and build a diagram. We call it our system boundary diagram that is lots of boxes and arrows that connect everything. That's a very typical chemical engineering thing to do as well. And we try to figure out how can we quantify all of these flows. Now, if I were a mining company and I was in existence, I would have all that information. Right. Like, I would know how much diesel fuel I bought for my mining equipment last year. And I could figure out, you know, how much emissions arose from the use of those fuels in my equipment. I would know roughly how much water I used, how much natural gas I used, how much electricity I use because I'm paying bills. Right. So when you're inside a company, undertaking life cycle assessment is perhaps, it can be hard to gather all that information. But it's easier than, than, me as an outsider trying to figure this out.
Starting point is 00:28:23 So the way that we in my group try and figure out energy and water consumption and pollution from mining is through using permitting documents. And if the mine exists, what they've reported. If they needed to report their emissions to the federal government, what they've reported. And so through figuring out the consumption and emissions over the entire course of the life of the mine and how much minerals have been produced over the life of mine, you can calculate then the total emissions or energy input per unit of product. So you can imagine like per unit of copper.
Starting point is 00:28:58 I mentioned, so mines are also interested in electrifying their equipment and they use electricity anyways with their existing equipment. And so we don't just take the amount of electricity that's used on site. We account for the energy that's consumed to make that electricity, whether it's from natural gas or from coal. So we consider the upstream emissions and energy consumed from getting all of the fuels to the power plant, for example. Is that scope three that we've been here with this?
Starting point is 00:29:27 Yes. So in like corporate carbon accounting, something like that would be actually be called scope two, the emissions from the power plant. So like the on-site emissions are scope one. And then going one step upstream is the scope two. And then scope three is like associated often with like consumer use of products. and it's very hard to quantify scope three. In LCA, we don't necessarily divide things up in those scopes,
Starting point is 00:29:52 especially for like water consumption, because we're looking beyond carbon accounting. But we do, like the words life cycle are meant to indicate that we don't just account for the on-site burdens, but we also account for the upstream burdens in figuring all this out. And so, you know, what we hope to be able to do is to be able to, as best we can, with the information we can get our hands on, develop these comparative impacts for different
Starting point is 00:30:20 minds. And so we've been working on that. It's, you know, everything takes a while. So we've been working on that for the U.S., and then we've been working on that for Australia and Chile. So I've been very fortunate to receive support from our Buffett Institute for Global Affairs here to work with undergraduates and also partners in Chile and Australia at universities to try and figure this out to help us understand how emissions are reported, for example, to governments in Chile and Australia, because it can be hard to navigate those websites, even for our own websites I'm familiar with the U.S. government can be a little tricky, and then when you go to another country, you've got to learn the ropes. So it's nice to work with partners who already know the ropes.
Starting point is 00:31:01 And so you can imagine a world in which we're able to, through using a method like life cycle assessment, come up with these per ton impacts that can be compared across different minds. and you can really understand, well, if I source my copper from Australia versus Chile versus Arizona, you know, what are the relative environmental impacts? And of course, we care about greenhouse gas emissions, but as we discussed, water consumption, water pollution are really important metrics to consider. Once you have this data collected and you know if the mines in Chile or the mines in Australia or the mine in America is, the impact is this.
Starting point is 00:31:40 Mm-hmm. Then what? Once we know that, what do we do with that information? Well, in my view, there are kind of two things we could do with that information. And it depends on the sort of stakeholder group. Actually, maybe three things. So one thing is if the government, you know, under the previous administration, decarbonization was a big priority. And there were incentives put in place in the Inflation Reduction Act to try and encourage decarbonization technologies to take off in the U.S.
Starting point is 00:32:14 These include lithium ion batteries. And there was a provision in that act to try and shift the supply chain for batteries and for minerals to the United States. And there was a portion of that policy that said that the EV that is sold is only tax credit eligible. So they offer tax credits so consumers would be more interested in buying EVs. But the vehicle would only be tax credit eligible if 80% of the market value of the minerals in the battery came from the U.S. from Chile or from
Starting point is 00:32:47 from a U.S. free trade partner, which include Australia and Chile, among other countries, or recycling, and recycling had to happen in North America. So they put this policy out, and the focus was on the market value. But a student and I wrote a paper that explained, A, that those targets were nearly impossible to meet by the deadline, which was 2027, but B, that, you know, accounting for the market value didn't really address this concern around the environmental impact and the social impacts of acquiring these minerals. So if the U.S. government is encouraging this policy, it should also account for the environmental
Starting point is 00:33:25 burdens and try not to put more burdens on individual communities. And so we made that arguments by then knowing that these types of metrics don't really exist in a comparable way. So one stakeholder is a government, whether it's federal or state level. The EU currently has a battery passport program where they are looking solely at the carbon emissions associated with producing batteries that are used in the EU. But the mining step, they basically just give you a value. So if you say, well, this is my battery chemistry, they can give you a value for what are the
Starting point is 00:34:01 greenhouse gas emissions associated with producing that battery at the mining stage, which to me is a big mistake, A, that they are not looking more directly at, like, well, what is the supply chain, and that they're only looking at greenhouse gas emissions. But so, and because the EU- Is that better than nothing or is actually worse, worse than something? I think it's better than nothing. And I think it is, you know, really admirable that the EU legislators realized that through pushing towards decarbonization, they are creating this demand for a whole supply chain that's, you know, relatively young and that there is an opportunity maybe to steer it towards being less carbon intensive. So that's great. And I think, you know,
Starting point is 00:34:45 it at least gets people thinking about it and doing something about it. And oftentimes, not always, but carbon emissions are oftentimes tied to things like water consumption. Because if you're making the process more efficient overall, maybe you're going to emit less emissions from using energy like natural gas or electricity, but you're also needing less water to run that process. So the things can't, they can be coupled and have co-benefits. So I think it's a great start. I hope that they continue to kind of drill down on some of these other effects that are really felt by local communities. So category one of like who would use this as governments if they want to sort of.
Starting point is 00:35:23 And you can say, well, why should a government care? And part of it is, well, if you think decarbonation is important and you know we need more minds, you want communities to feel comfortable with having these minds. So part of that is the environmental burdens. So if you say, like, well, we now have a stipulation around the environmental burden needs to be, like, at or below a certain number, or you get certain sort of credits if the lower your number is. Like, those are ways that a government can sort of encourage better performance, better environmental performance in the supply chain. So there's governments. And there's companies, and I think that companies might want to tailor their supply chain to be less environmentally impactful.
Starting point is 00:36:02 In part because, again, the less environmentally impactful, your supply chain is when it involves mining, I think that there will be one way of saying is less community resistance and so there's less risk in your supply chain. So the better you can do in acquiring your minerals for, if it's an energy storage device, from mines that are operating in a very socially
Starting point is 00:36:22 and environmentally responsible manner, you have less risk of protests, for example, going to shut that mine down, which happens around the world. Somewhat frequently. But less profit. Yeah, exactly. That's the reason why a company might want to do it
Starting point is 00:36:35 even if they think, like, well, maybe corporate social responsibility might not be their top priority, but there is a risk of supply chain disruption from adverse environmental consequences for communities near the mine that's supplying them. And the last stakeholder category is the communities themselves. So, you know, we've worked with communities in Minnesota who are, you know, told, like, we need these minds because we need to do the energy transition. And then they think, well, you know, why us? Like, what role does our community, our location play in this broader supply chain question. And is it really true that, you know, we can have better environmental performance, for example, for nickel mining here in Minnesota
Starting point is 00:37:14 than other places that might mine nickel like Indonesia? You know, so being able to tell that story to a community and really about the, and for a community to understand themselves, how they feed into this broader decarbonization goal, I think, is important. And we have seen how communities, like, it's helpful to them to understand. We've presented LCA results to a couple of communities in Minnesota, and it's helpful to them.
Starting point is 00:37:41 They're like, oh, okay. Like, I understand now how this fits in to this broader story, and it helps understand, like, where, if they're going to push towards encouraging companies to take action to reduce pollution, where should they put their focus? That's the other thing that life cycle assessment can help you do. It can help you pinpoint what is kind of like the worst offender
Starting point is 00:38:00 in this overall process, that if you were going to pick one thing to say this is what we need to work on to improve. That helps you identify that one thing. Give me an example because your work is super important. What you're highlighting is super important, but it's very long-term benefits to humanity focused versus short-term profitability driven, which is unfortunately the means of the way the world tends to operate. Give me an example of a frustrating moment where you've been heads down in your research and you're just tired of hearing about the economics, tired of hearing about this and that, and you just want to grab someone by the shirt and just be like, listen.
Starting point is 00:38:44 What do we need to listen to? I think what's frustrating is that the technology exists to give communities and governments and consumers more information about the environmental effects of mining. Like technology is there. It's just that to adopt that technology and potentially adopt more, expensive pollution control technology that costs money and it's not for that reason it's not attractive but to your point it's the long-term thinking of like well people are going to get upset you know when when water quality declines when we are now talking about you know we happen for a while
Starting point is 00:39:21 but water rights in the southwest like who gets the water i think that there's just not maybe an appreciation for how if the investment was made to provide more information and to provide more efforts to protect water quality and water consumption, that would generate a lot of goodwill that could translate into less risk to the operation, either from lawsuits in the U.S. or, you know, we don't see as many, like, protests, people are going to shut down facilities as happens in other countries, but it does happen in other countries. And so I think that is, like, that is very frustrating because many mines, mining,
Starting point is 00:40:03 companies have, you know, community relations activities and they will invest in the community, they will build a new school, they will, and those are all wonderful things. But I think that what's frustrating is even though the technology exists to do a lot better with information sharing and pollution control, you know, it's just when you do out the balance sheet, right, it doesn't, the risk calculation side of it isn't there. It's very hard to quantify and so it doesn't come into play. If you're doing something as important as this, to the world that affects the world in such an important way. There should be some kind of process that puts that into place to make it go.
Starting point is 00:40:43 I want to be sure to mention that there are industry initiatives to report, like sustainability standards for the mining industry. It's not that those don't exist. And we reviewed kind of what their requirements are. And really, sort of transparent reporting or calculating a life cycle, results is never required. There's one standard called Irma that I think is best in class, in my opinion, and it does like sort of offer one of the things you can do when you are a mine working with that standard is you can say you will make data available upon request,
Starting point is 00:41:25 primarily around air pollution. But then as a community member, like you need to know that's an option. You need to know how to do it. And it's very challenging. as it's compared to what SQM is doing with this like having the sensor data available online. You still need to know what to do with that, but at least it's there and you need to go through the whole process to request it. So in my view, that mining standard is a great start and there's so much more that we can do again to address, you know, like the cynical view is like we want to limit risks to shutdowns of mines because we need to plow ahead with decarbonization. That's kind of like we need the more corporate way of looking at it. And of course, the community way of looking at it is like we want to protect our environmental quality where we live.
Starting point is 00:42:08 I like cynical. I can do cynical. So back to the differentiated market. I drink fair trade coffee sometimes. I eat fair trade chocolate sometimes, not all the time. But it's something that I can, I understand culturally. It's in, it's in me. I've grown up with it. I understand it. Can that, what you're talking about is kind of the same thing but for lithium and copper. Can it work for lithium and copper? That's not coffee. It's not a consumable that we're all eating and drinking. I know it's all in our technology. I'm surrounded by it.
Starting point is 00:42:43 It's literally all around me, but I don't think about it in that way. Yes. I think that's, you know, part of the problem is, like, from a consumer perspective, you know, we're not consuming just copper, right? So, and there are certification standards. So, like, if you buy stuff on Amazon, there are some certification standards that apply to electronics. But, again, it's, like, very qualitative, in my opinion, and kind of squishy. But even if it were quantitative, you know, we've done this, as you're saying, like, there are lots of, like, equal labels for lots of different kinds of products.
Starting point is 00:43:15 And that's not necessarily my area of expertise, but from when I hear people speak about this at conferences, you know, it's that there's so many labels. and consumers don't necessarily know like how best to interpret those labels. So Fair Trade Coffee, I think that one has like, jump the shark or like that is like now like mainstream enough. And so the problem I see with a consumer facing sort of label like that is that every device has like multiple minerals in it. And then there's like the rest of it that has to be manufactured somewhere.
Starting point is 00:43:48 And so it's a really complicated supply chain. But I think it's definitely worth thinking. about and we have technology like blockchain to help us do better job tracking, you know, even compared to 10 years ago. But actually, the New York Times- It's been a while since anybody said that on thinking on paper. I mean, I think that, you know, and then there's just lots of ways, I think, that we can leverage advances in technology to try and make this a reality. The New York Times just had a piece, I think on the 26th of April, that was talking about gold, the U.S. Mintz Gold.
Starting point is 00:44:22 and there had been some legislation in Congress to try to limit the chances that that gold would have been acquired from minds that have social and environmental problems. But it's not working. So the New York Times tracked some of this gold to like Colombian drug cartels. So it just gives you a sense of like someone's really trying, you know, to do right here, to do this well. And it's not working for something like gold that is just used. used as gold. It's not like being put into a device. It's just gold. So it is hard and there have been efforts to like, there's three T's Tandolin tin, and I'm forgetting the third where people tried to like develop, you know, one conflict-free diamonds, right, is another one that's a big deal.
Starting point is 00:45:13 These are my grandmothers. So I didn't think why are new diamonds. But, but yeah, so I think that, You know, but those also have problems, right? So, like, you know, if you look hard enough, you're going to uncover cases where something that's sold as a conflict-free diamond is not. And so now we're just growing them in labs. But, yeah, so it's like, I don't want to, like, say this would just be easy. Like, it's, it's hard, but I do think it's, I think it's worth to me. 100%.
Starting point is 00:45:40 No, two quick comments there. We aim to connect the dots on taking on paper. You mentioned gold. You mentioned blockchain. There was actually a study comparing the mining of gold. to the miners in blockchain. Gold actually didn't do as well environmentally as the miners in blockchain, believe it or not. I'm sure there's some mafia and some nasty nefarious parties involved in Bitcoin,
Starting point is 00:46:02 probably more so possibly than gold. Could be possible. But this conversation real quick, like as we're talking about telling the story, right? Because this is story. Your culture starts with story. Mark, you mentioned culture. We know it with fair trade coffee. It's acceptable.
Starting point is 00:46:20 It's kind of a sense of like if you're drinking it or you buy it, you feel like you're contributing and you're doing the right thing. So picture this. You go on to Apple's website. It's time for a new laptop. And you're looking at the models and you're seeing that comparison chart. You know, the Model A, Model B, Model C, Model A is the cheapest. It's pretty fast. Model B is a little more expensive.
Starting point is 00:46:43 It has another chip in it that makes it does something. Model C, fair trade, copper and lithium. for a premium. How does the world react? Yeah, you know, I had a friend a while ago. She had a phone that was meant to be conflict-free, all-conflict-free minerals. She's the only person I've ever met who had a phone like that.
Starting point is 00:47:06 You know, I think that, because she just really, it was a top priority for her. And I think that, you know, we are hearing so much about affordability. I think that, especially in today's environment, environments, people are just focused on, you know, cost effectiveness and things being affordable. So I don't see a world in which consumers are going to really move on this opportunity for lower environmental impact products, electronics, like an Apple laptop, you know, except for a small group of folks who have that extra sort of disposable income. Yeah, that's pretty hard. Because it's also
Starting point is 00:47:48 like we're talking mainly about things that aren't happening in the U.S. And so I think it's really, of course speaking as a U.S. person, I think it's hard to kind of like really have that click for people. And, you know, we are also just bombarded with all sorts of things we should care about. And it's just, I think for many people, even me, like, who has some training in this area, it's like, it's a little bit overwhelming to know, like, well, which things can I do that will really make a difference? And I think that is, Like if I'm going to spend extra money on whether it's fair trade coffee or my laptop, like which one should I do?
Starting point is 00:48:24 And that's really hard to offer that kind of comparison. Yeah. So it's tough. We need Brad Pitt and we need a movie. We need a big, huge Hollywood blockbuster to change the cultural view of all of this. Conflict-free phones sound incredible. Do you actually remember the premium that your friend paid for that phone or where they got that phone or how it compared to?
Starting point is 00:48:46 This was back. I used to work with her like in the time. 2016, so we're talking a decade ago. But I do remember, frankly, it didn't work as well because it wasn't like a famous brand, so she would get frustrated with it. But she said, yeah, but it's the responsible phone to get. And so she was willing to tolerate, you know, lower performance for this phone. Now, again, this was 10 years ago, so I'm not, I haven't kept up with like how this,
Starting point is 00:49:10 the hobbies options are available to go. Just a quick, quick search. There's something called Fairphone, Fairphone Gen 6 that's out right now. That's a conflict-free phone. Conflict-free cell. Conflict-free earbuds? Wow, interesting. It's quite scary that that makes me realize
Starting point is 00:49:28 or perhaps think that almost everything is conflict tech. Everything comes around. Yeah. Yeah. Conflict did. One very specific, you know, social impact, which is really an important social impact, that we want to avoid sourcing minerals from areas
Starting point is 00:49:45 that, like, the existence of minds causes conflict. And I did a study with a friend, I think we published that in the 2018, no, no, 2021 ballpark around Cobalt from the Democratic Republic of the Congo and some of the social concerns around that and thinking about, like, can we, it's very difficult to quantify those effects in the same way that life cycle assessment can quantify some of the environmental effects. So we were, she is an anthropologist. Her name is Sarah Young, and we were trying to figure out, like, can we do this? And the answer is really hard. So I had a point here. Oh, so yeah, so conflict is just one of many social ills, and it's super hard to quantify. And then it's not, it doesn't get to like the challenges of things like, you know, your water's polluted.
Starting point is 00:50:32 And so, yeah, I don't know. I guess as an engineer, you know, I'm wanting like this, this like even playing field for assessing all of these different problems that can arise in mineral supply chain. And then, you know, you need to work with people who really understand. how do we communicate this to public? So something gets through all the other noise that people are dealing with. How do we communicate the importance of this to policymakers? And how do we continue to work with industry to help maybe advocate for doing these types of sort of transparent data collection and sharing can limit your risk of losing what I think
Starting point is 00:51:07 of someone as a social license to operate? Jennifer, thank you for thinking on paper with us. That was awesome. We have to do a part two because we've only just started, really. I wanted to talk about processing. I mean, China processes much of, much of that they like, was it? 15% of the global supply. They process 65%.
Starting point is 00:51:32 The boom, bust cycle of minerals. Yeah. But we'll save that for next time. I just want to leave you with a, with a depressing thought, a cynical thought. Oh, no. Yes, the metals that are critical today might not be so critical in 10 or 20, 30 years and perhaps what we're doing now
Starting point is 00:51:53 or what you're trying to do with lithium and copper will set precedent that when those metals do inevitably change check out our episodes on quantum computing if you don't believe they will change and there'll be something, a process, a cultural foundation to make sure that we don't make the same mistake again. So thank you for enlightening our audience. It's been superb. Well, thank you. It was a pleasure to speak with you and yeah, happy to chat again.
