Global Witness flags battery harm
- Global Witness said on May 3 that waste from Ghana’s Nsuta manganese mine is poisoning nearby communities linked to the EV battery supply chain. - The group says it interviewed more than 150 residents near the mine, while separate U.S. reporting counts more than 100 proposed lithium projects. - The bigger shift is from “more batteries” to “whose batteries, from where, and under what safeguards.”
Battery supply chains are having a trust problem. The sales pitch for EVs and grid batteries is cleaner air and cleaner power. But the mining behind them can still look brutally old-school — dirty water, dust, weak oversight, and communities carrying the cost. That tension sharpened this week when Global Witness published a new investigation into manganese mining in Ghana, just as fresh reporting in the U.S. mapped the scale of a coming lithium rush.

Global Witness published an investigation on May 3 saying waste from a Ghana manganese mine tied to EV battery materials is creating toxic conditions for local residents. The group says people living near the mine described chronic he(globalwitness.org)suta, a long-running manganese district that has become newly relevant because manganese is increasingly important in newer battery chemistries. (globalwitness.org) ### Why manganese? Lithium gets most of the attention, but manganese matters because battery makers use it in cathode chemistries meant to balance cost, safety, and performance. Basically, if automakers and storage developers want huge volumes of batteries witho(globalwitness.org)ntal failures are no longer some distant side issue. They sit inside the clean-energy value chain itself. (globalwitness.org) ### What’s the U.S. angle? Inside Climate News published a data project on May 3 showing that more than 100 lithium projects have been proposed in the U.S. alone. That does not mean 100 mines are about to open. But it does mean the next phase of battery manufact(globalwitness.org)ory are different cases, but they point at the same bottleneck — battery demand is moving faster than social consent. (insideclimatenews.org) ### Why are critics talking about transparency now? Because supply chains get murkier as they scale. A battery pack sold in one country can depend on ore mined in another, processed in a third, and assembled somewhere else entirely. When that happens, companies can talk a lot about decarbonization while staying vague ab(insideclimatenews.org) transition minerals can still produce the same old pattern of profits flowing outward and damage staying local. (globalwitness.org) ### Where do lawsuits fit in? A smaller but telling piece of this week’s conversation came from Australia, where SolarQuotes revisited a case involving battery reviewer Stefan Fischer and Deep Cycle Systems. The point was not that one lawsuit defines a(globalwitness.org)st data, buyers learn less right when they need to learn more. (solarquotes.com.au) ### So what should buyers and developers watch? Traceability first. Not just the country of origin, but the mine, processor, and grievance trail. Then lifecycle and safety documentation — especially for large storage projects where fire risk, recycling paths, and procurement disclosures all ma(solarquotes.com.au)tion too. (globalwitness.org) ### Is this anti-battery? No — it is anti-magical thinking. Electrification still needs batteries. But the industry is running out of room to claim climate benefits on the front end while treating extraction harms as somebody else’s problem on the back end. Cleaner technology only stays politically durable if the supply chain gets cleaner too. (globalwitness.org) ### Bottom line? This week’s battery news was not a breakthrough in chemistry. It was a reminder that the hard part may be legitimacy. More mines are coming. The real question is whether the industry can prove those materials were sourced without poisoning the people living closest to them. (globalwitness.org)
