Europe's automakers face new CO2 emissions headache

European automakers, already battered by the region’s economic downturn, face a fresh financial headache if the European Union implements, as planned, a new way of testing CO2 emissions from cars starting in 2017. The EU wants to replace the New European Drive Cycle (NEDC) test, which measures CO2 emissions and fuel economy of new vehicles, by a more accurate United Nations-sponsored test cycle called the World Light Vehicle Test Procedure (WLTP).
