Summary: Not much for emissions since there are other larger contributors to emissions, and the electricity for EVs need not be from clean sources. But it nonetheless helps the air of megacities.
- Even if the ambitious targets of the world’s biggest economies are met, and internal combustion engines give way to electric or other zero-emission vehicles by 2040, the total impact on global carbon dioxide emissions will be minimal, according to a new study released Tuesday.
- According to Laura Cozzi, the head of the IEA’s energy demand directorate, EVs will only displace 1% of expected global CO2 emissions in 2040.
- Increases in emissions from air and sea transport will more than offset the savings from passenger cars unless new technologies can somehow make the same kind of impact on them as Elon Musk et al. have had on the car industry.
- Such megatrends explain why countries such as China and India, which account for well over half of projected energy demand growth through 2040, are throwing billions of dollars at renewable energy: not so much to combat Climate Change, as to improve air quality in cities that are already choking, but which continue to attract millions of new migrants from the countryside every year.
