In 2016, about half of new cars in Europe were powered by diesel fuel. In the U.S. and Japan the market share of diesel is negligible. Within the EU, diesel cars account for only about 20 % of new sales in the Netherlands. The reduction of the CO2 emission level of new cars is independent of the diesel market share. Average emissions in Japan (116 g/km), for example, are lower than in the EU (118 g/km), despite the lack of diesel cars on the Japanese market.
