The EU's and China's fleet emissions standards are forcing manufacturers increase their electric car sales. All manufacturers need to sell enough EVs (BEV, FCEV, and plug-in hybrid) to avoid fleet emissions fines.

And future bans on new car sales of petrol and diesel cars have been announced in various states and countries.

Norway by 2025: https://www.thedrive.com/news/7917/norway-doubles-down-on-pl...

The UK by 2030 (but plug-in hybrids still allowed): https://www.bbc.com/news/science-environment-54981425

California by 2035: https://www.npr.org/2020/09/23/916209659/california-governor...

Also London's Ultra-Low Emission Zone (ULEZ) that is going to be expanded to most of Greater London, and where non-EVs, including hybrids, will have to pay £12.50 a day. That will immediately make an ICE car unaffordable compared to a low-cost BEV like the Kia e-Niro, VW ID.4 or Renault Zoe.

Stopping production of petrol/diesel cars and lowering carbon taxes on electric cars is pretty strong encouragement though.
