OECD published a report[1] on EVs lately. I haven't read it but according to various press sources it claims that EVs might make things worse, e.g.[2]:

"The report assumes that diesel and gasoline-powered cars are going to be replaced with electric vehicles, eliminating tailpipe emissions, but that problematic PM emissions will remain or even increase."

Maybe a good time to fuel research into new material ?
