CO2 Emissions higher in use than European Makers Claim

The gap has widened between the fuel-efficiency that carmakers declare for their models and the reality for drivers, with luxury German vehicles showing the biggest divergence, a study has found.

The research by the non-profit International Council on Clean Transportation (ICCT) found "real-world" carbon emissions for new cars based on fuel consumption are about 25% higher on average than carmakers say, compared with 10% a decade ago.

The findings will add to pressure for the reform of EU vehicle testing procedures to ensure that advertised fuel-efficiency values better reflect normal use. That in turn could make it harder for manufacturers to meet a new EU carbon dioxide (CO2) vehicle emissions target proposed for 2020.

BMW reported emissions figures for its vehicles on average 30% lower than those found in actual use, said the report, published on Tuesday.

BMW was not immediately available to comment on the findings reported by the ICCT, which aims to improve efficiency in transportation to benefit public health and mitigate climate change.

Volkswagen AG's luxury unit Audi had the second widest disparity, with reported emissions some 28% below actual use, while Mercedes showed a gap of 26%.
