    The first widespread introduction of catalytic converters was in the United States automobile market. To comply with the U.S. Environmental Protection Agency’s stricter regulation of exhaust emissions, most gasoline-powered vehicles starting with the 1975 model year are equipped with catalytic converters.[1][

    One of CARB’s responsibilities is to define vehicle emissions standards. California is the only state permitted to issue emissions standards under the federal Clean Air Act, subject to a waiver from the United States Environmental Protection Agency. Other states may choose to follow CARB or the federal vehicle emission standards but may not set their own.[2]

      Yes while CARB may effect other vehicles sold in the US (the same market), it doesn’t necessarily effect cars sold in other markets on the other continents. As I said, they generally build different cars for each market which is why Europe gets so many diesels, Australia gets Utes, the US gets SUVs in all flavor, etc.
