The European Parliament is reportedly close to a compromise on the time period for planned curbs on carbon dioxide emissions for carmakers, according to a German newspaper report.

Frankfurter Allgemeine Zeitung said that under the terms of the compromise, manufacturers would no longer be obliged to reach emission targets in 2012 for their entire fleets but only for parts thereof.

This would imply only 25 percent of their fleets would have to fulfill targets of emitting less than 130 grams of carbon dioxide per km on average during the first year, the newspaper said.

This would then rise to 50 percent and 75 percent in the second and third years respectively, while all cars would have to hit the targets in 2015, it added, citing Werner Langen, chairman of the German Christian Democrats in the European Parliament.

German carmakers say that current European Commission proposals discriminate against them because they make more large cars than other EU carmakers.

German-made cars emit 170 grams of carbon dioxide per kilometre driven on average, while the figure for French and Italian cars is close to 120 grams.
