Electric vehicles (EVs) are often promoted as a major solution to climate change. In fact, I myself have advised readers to consider buying them. Since they run on electricity instead of gasoline, they don’t produce tailpipe emissions, which can significantly reduce carbon dioxide coming from cars.Since transportation alone accounts for about 20% of global greenhouse gas emissions, switching over to EVs would massively decrease total emissions. However, EVs aren’t completely environmentally friendly. One of the biggest concerns is the mining required to produce their batteries.

EV batteries rely on minerals like lithium, cobalt, and nickel. Mining these materials has severe consequences on the environment. In particular, surface mining, which extracts minerals from the surface by removing dirt, causes extensive erosion and habitat destruction, as well as poor air quality and high water usage. Because of these impacts, some critics argue that electric vehicles may not actually be much better for the environment than traditional gasoline cars.

However, when you look at the total lifespan of these vehicles, it’s clear which one is more harmful. Gasoline cars produce emissions every time they are driven because they burn fuel. Electric vehicles do create more emissions during manufacturing due to their batteries, but once they’re on the road, they produce no direct emissions while driving. Over time, this usually makes EVs much cleaner overall. Electric motors are also far more efficient than gasoline engines, meaning they use less energy to travel the same distance.

Another important factor is the electricity used to charge EVs. As more electricity comes from renewable sources like wind and solar, the emissions associated with charging electric vehicles will continue to fall. Gasoline cars, on the other hand, will always rely on burning fossil fuels and will continue to emit CO2 throughout their lifespan. Mining for battery materials is an environmental challenge, and it needs better regulation and improved technology. But when scientists compare the full lifecycle emissions of electric and gasoline vehicles, EVs generally come out ahead. They are not a perfect solution. But even considering the environmental costs of battery mining, they still tend to be better for the climate than gasoline-powered cars.

Here’s what you can do to help: EV batteries use materials that can be reused instead of mined again. By recycling old batteries instead of throwing them away, over 95% of the materials used in them can be recovered and used to make new ones.
