I think you’re underestimating atmospheric transport. NOx from China makes up a large portion of the pollutant in California, more than enough to offset local reductions over the past couple decades.

- trgn 3y agothanks for the link. Is the idea that EV-manufacturing would increase pollution in China, thus increasing pollution in US?
- labster 3y agoNOx is a product of combustion with an excess of oxygen (too little O2 and you get hydrocarbons; both lead to ozone). You don’t need to make EVs with fossil fuels, so there’s no need for the air pollution to happen at all. Pollution from mining is another problem altogether of course.
