My sentiments on pollution are the same as yours. But I wish it were that simple.
China has the largest sales volume of EV in the world but it also is responsible for the highest greenhouse gas emissions globally. The electricity that charges EV is coming mainly from coal in China. It means that pollution is not just about automobile sector, it has to be handled with a holistic approach.
The energy sector is causing most of the harmful emissions. This sector includes construction, manufacturing, transportation, and electricity generation. So all of the energy sector requires attention at the national policy level, not just with promoting the use of EV.
