The push toward renewable energy solar panels, wind turbines, EV batteries — isn’t wrong, but it’s not free of environmental trade-offs. a study published in Nature Communications on December 21, 2025 found that the world’s increasing demand for the metals and minerals that make these technologies possible is fueling massive mining expansion that’s now a major driver of deforestation and carbon emissions. mining isn’t just a local land use issue — it’s reshaping forests, biodiversity and climate feedbacks at a global scale.
between 2001 and 2023 researchers mapped 236,028 mining sites worldwide, showing that direct forest loss from mining is about two to three times higher than previous estimates once you include unrecorded and informal operations. that deforestation adds up: roughly 19,765 square kilometres of forest have been cleared due to mining activities in those two decades, releasing an estimated 0.75 petagrams (750 million tonnes) of CO2 into the atmosphere — emissions on the same order as many fossil fuel sources.
what’s especially striking is what’s being mined. minerals critical to clean energy nickel, cobalt, copper, lithium, and related elements are over-represented in deforestation hotspots compared with other minerals. in the early 2000s most mining-linked forest loss was from all types of extraction, but after 2012 the majority of deforestation around mines was for minerals increasingly used in renewable tech, not just traditional fuels or metals. nickel mining for EV batteries and energy storage systems, for example, often involves clearing biodiverse tropical forests.
this is more than a mapping exercise. forests aren’t just trees: they’re carbon sinks. when they’re cleared for mines, you lose both the stored carbon and the future sequestration capacity of that land. that’s not usually included in climate plans or sustainability reports for the renewable sector, which tend to focus only on emissions from electricity generation or vehicle tailpipes.
the upshot? the clean energy transition can’t just focus on cutting operational emissions. if mining-linked deforestation continues unchecked, it undermines climate goals by adding CO2 emissions and degrading ecosystems that regulate climate and water cycles. it also raises tough questions about equity, since many of the worst impacts hit biodiverse, low-income regions and Indigenous lands. balancing renewable deployment with forest-smart mining, recycling, stronger impact assessment and protection of vulnerable ecosystems is crucial if decarbonisation really means lower total environmental cost.
