Only two companies achieved the voluntary average CO2 target of 140 g/km that European automakers set for themselves in the late 1990's to avoid actual government sanctions. Fiat and Mini were the big winners with emissions of 138.2 and 139.6 g/km, respectively. The worst offenders were Porsche (275.6 g/km), Land Rover (249.2 g/km) and Jeep (218.7 g/km).
The figures were published by Clean Green Cars, which also pointed out that "Every manufacturer with average new car emissions significantly above 200 g/km of CO2 saw sales slump from January to June." Clearly, voluntary agreements are working. Why oh why then did the EU have to implement non-voluntary emissions targets for 2012? Press release below the jump.
