Electric vehicles (EVs) are often lauded as the greatest solution to global pollution, reducing carbon emissions and combating climate change. Their quiet engines, non-existent tailpipe emissions, and promise of energy sustainability have captured the interest and investments of both consumers and governments alike.
However, beneath the eco-friendly marketing campaigns and government subsidies lies a darker reality that contests the notion of EVs as a truly eco-friendly alternative. From the environmental devastation caused by mining to the reliance on fossil-fuel-powered grids, electric vehicles come with significant hidden dangers to the environment which require deeper consideration.
The Environmental Toll of Battery Production
A fundamental part of electric vehicles is their batteries. These batteries are primarily lithium-ion variants, which rely on metals like lithium, nickel, and cobalt. Mining these materials has a devastating and lasting impact on the environment.
Lithium Mining
The production of 1 ton of lithium, for instance, emits nearly 15 tons of CO2. To extract enough lithium for 100 cars exhausts about 2 million tonnes of water. In South America’s lithium triangle, which is Chile, Argentina, and Bolivia, intensive extraction has led to severe water depletion. 65% of Chile’s regional water alone is used for lithium mining.

Nickel Mining
Nickel mining presents an equally devastating impact on the environment. Indonesia has begun playing a major role in global nickel production. This is largely due to Chinese investment under Beijing’s Belt and Road Initiative. Massive mining complexes in Central Sulawesi and Halmahera have destroyed native forests, polluted waterways, and displaced indigenous populations.
Workers face unsafe conditions with inadequate access to health care, frequent injuries and even fatalities. Ethics surrounding their working conditions and hours are incredibly questionable. Some workers are even overworked and underpaid. These operations are powered by low-grade coal-fired power stations, producing what industry insiders call “dirty nickel.” This material ends up in EV batteries and is incorrectly marketed as environmentally friendly.
Cobalt mining
Cobalt mining is another tale that has sinister undertones in the electric vehicle case. Electric vehicles drive 73% of cobalt demand globally, with lithium-ion batteries consuming 63% of annual cobalt production as of 2021. In the Democratic Republic of Congo (DRC), which accounts for 74% of global cobalt mining, exploitative labor practices, including child labor take place.
It is estimated that 40,000 children work in the DRC’s cobalt mines, in hazardous, “rat-hole” mines exceeding 30 meters deep. Cobalt mining in the DRC has led to toxic metal contamination in local ecosystems, affecting crops and freshwater sources. This further puts into question ethical concerns surrounding EV battery production.
Fossil Fuels Powering Green Machines
While electric vehicles themselves produce zero tailpipe emissions, the energy required to charge them often comes from fossil-fuel-powered suppliers and energy grids. In countries like India, where 61% of electricity is sourced from coal-fuelled power plants, EVs indirectly contribute to high levels of CO2 emissions.
In Indonesia’s nickel mining complexes, low-grade coal is barged in from Kalimantan. These fuel smelters and power stations emit staggering amounts of pollution. EVs are fronted as a green alternative but depend on batteries created in some of the most environmentally damaging industrial landscapes.
Economic Fallout
The rise of cheap nickel from Indonesia has adversely affected Australia’s once-thriving nickel industry, resulting in the loss of 7,000 jobs and billions in revenue. Despite a 2023 Memorandum of Understanding promising cooperation on EV supply chains, Australia and Indonesia have made little progress. Instead, Indonesia and China dominate global markets with “dirty nickel,” undermining environmentally responsible mining operations elsewhere.
Batteries Beyond Their First Life
While lead-acid batteries used in traditional vehicles are easily recyclable, only 5% of lithium-ion batteries are recycled annually. Inefficient and costly recycling technology leads many batteries to landfills, where they destroy ecosystems, pollute drinking water, and poison the ground.
Some manufacturers have taken steps to address this issue. For example, Nissan repurposes old EV batteries to power automated guided vehicles in factories, while Volkswagen and Renault have established recycling plants. However, these efforts are far from widespread or sufficient to mitigate the growing pile-up of discarded batteries.
Waning Demand for Electric Vehicles
Despite government subsidies and tax incentives aimed at boosting EV adoption rates globally, demand remains inconsistent. In countries like the U.S., factors such as affordability, limited access to charging ports, and long charging times deter many consumers from making the switch. Major automakers like Ford and General Motors have scaled back their EV investment plans due to a lack of demand.
In India, a country grappling with high transportation-related CO2 emissions, the government has set ambitious targets for EV adoption by 2030. However, reliance on imported lithium-ion batteries from China adds to the environmental damage through transportation emissions. Rising raw material costs further threaten affordability; lithium prices alone have surged by 70% since January 2022.
A Call for Sustainable Practices
Electric vehicles (EVs) offer reduced noise pollution and zero tailpipe emissions, but their environmental impact spans the entire lifecycle. From mining raw materials to battery production and disposal. Governments must enforce stricter regulations on mining operations to mitigate environmental damage caused by extracting lithium, cobalt, and nickel.
Transitioning power grids from fossil fuels to renewable energy is essential to reduce indirect emissions during EV charging. Investments in efficient recycling methodologies can extend battery life cycles and reduce dependency on raw materials, while manufacturers should disclose carbon footprints at every production stage to enable informed consumer choices. Without addressing these critical issues, EVs risk falling short of their promise as a sustainable solution for decarbonizing transportation systems globally.
