ZEV regulation
This regulation, first adopted in 1990, requires automakers that sell more than a certain number of vehicles in California to sell a given percentage of ZEVs. The Regulation is getting stricter every year. From 2018, the ZEV sales ratio became 16%, and the ZEV eligible vehicles are electric vehicles (BEV), fuel cell electric vehicles (FCEV), and plug-in hybrid electric vehicles (PHEV). As of November 2019, 10 states have introduced this regulation, including California, Arizona, Massachusetts, New York, Oregon, and Maryland. In addition, the UK and France in Europe, and India, have announced that by 2040 and 2030, respectively, their sales of new passenger cars and vans will be limited to ZEVs, and new sales of vehicles with ICEs (gasoline, diesel, and other internal combustion engines) will be banned.
