Some studies have stated that electric cars (EVs) aren’t truly beneficial for the environment: the power necessary to create the battery and emissions from producing electricity could result in a larger carbon footprint than a gas-powered automobile. That was the essence of the argument. That is not the case, according to a new report. An electric vehicle has a lower carbon impact, unlike a fossil-fuel-powered vehicle, no matter where it is used, even if it is charged on a coal-fired electric grid.
One aspect is that making batteries is less polluting than initially anticipated. “Earlier studies from several years ago used what we now know to be obsolete data on battery manufacturing emissions,” explains Stephanie Searle, who works at International Council on Clean Transportation as a program director, which published the paper. “At the time, there were few automotive batteries on the market, and we didn’t have accurate data on the emissions associated with their manufacture. As a result, people had to make educated guesses about what those emissions might be. We now know that the usual emissions from creating batteries are much lower, unlike what we previously believed, now that the electric car sector has begun to scale up. We possess commercial-scale battery manufacturing plants operating and real data from them.” (Battery recycling could reduce these emissions much more in the future.)
The European Union, India, the United States, and China were all examined in the new study. Even though China and India still depend primarily on coal-fired power plants for electricity, pollution from charging an EV purchased today will continue to decline over time. According to Searle, a typical vehicle is utilized for 15 to 18 years. “So, if you purchase a vehicle today, the power required to charge it is one issue, but that vehicle will last for 15 – 18 years, and the electric grid will decarbonize over that time.”
Today, the transportation industry accounts for roughly 25 percent of greenhouse gas emissions, with passenger automobiles accounting for the majority of this. According to the report, moving totally to electric and hydrogen fuel cell automobiles is required to meet the objectives of the Paris climate agreement and prevent the worst effects of climate change—hybrid cars, as well as vehicles powered by other alternative fuels or biofuels, are insufficient. And, according to the analysis, to achieve a net-zero economy by the middle of the century, we will need to cease selling fossil-fuel-powered cars shortly. If a normal automobile is expected to last 15 – 18 years and we require to be driving entirely zero-emission cars by the year 2050, nations will need to stop new gas and diesel vehicle sales between 2030 and 2035.
