This briefing paper summarizes and analyzes preliminary data for 2015 recently released by the European Environment Agency (EEA) on CO2 emissions from new passenger cars in the EU. The EEA data show that the mandatory emission reduction target set by the EU legislation for 2015 has been met on average. New cars sold in the EU in 2015 had average CO2 emissions of 119.6 g CO2/km, which was 8% below the 2015 target, and 3% lower than in 2014.
