Car producing companies stand firm against the European Commission's project to impose the construction of less polluting cars. According to BBC News, the European Automobile Manufacturers Association (ACEA) attacked in a press release the suggestions recently made by the European Commission, considering that approving such measures would affect the entire European economy.

Less employees and new markets to be found are the main concerns of the car producers, who also claim the price per unit might rise for cars that comply with the new regulations.

In 1998-1999, most car producers selling units in Europe promised to build cars with less than 140 CO2 grams per kilometer (gpk) before 2008 or 2009. Still, the average was 162 gpk in 2005.

Emissions caused by street transport increased 30% since 1990, representing nowadays some 25% of all CO2 emissions.
