Fiat had the lowest average fleet CO2 emissions among automakers that sell cars in Europe in 2008, according to a study released today.
Fiat's average CO2 figure was 134 grams per kilometer, down from 137g/km in 2007, said JATO Consult, a consultancy division of JATO Dynamics.
Peugeot -- with a 2008 average of 138g/km -- was in second place. Citroen was at No.3, with its 142.4g/km average slightly higher than 2007, mainly because of the introduction of new, larger models.
David Di Girolamo, head of JATO Consult, said the auto industry made significant progress in cutting CO2 emissions with an average total reduction of 5.3g/km to 154g/km.
As part of its efforts to tackle climate change, the EU is asking automakers to reduce CO2 emissions to an average of 130g/km in a phased approach starting in 2012, with full compliance by 2015. Automakers that miss their targets face financial penalties.
ACEA, the European automakers association, had set a voluntary goal to reach 140g/km in 2008. Only Fiat and Peugeot reached the 140g/km goal.
