Researchers from the University of Cambridge have found that electric vehicles (EVs) with bigger batteries are more likely to be environmentally friendly. The study looked at the total lifecycle emissions of EVs, including the manufacturing process and electricity used to charge them. The findings showed that larger EV batteries result in higher emissions during production but lower emissions during use, making them more sustainable in the long run. The study suggests that policymakers should focus on increasing the adoption of larger battery EVs to reduce emissions from the transportation sector.
