The proposed target of 130gCO2/km by 2012 as the fleet average for each car manufacturer across the EU for all new cars will not only be an important step forward in tackling climate change, it will also incentivise the use of technology that will improve the fuel efficiency of new cars, said a spokesman.
The consultation formally closes on 3 October but those who wish to respond are urged to do so as soon as possible.
The British Government is urging the EU to adopt a longer term target of 100gCO2/km by 2020.
It says this would deliver a cut in CO2 emissions from new cars by an extra five million tonnes a year by 2020, in addition to the six million tonnes cut under EU proposals, and reduce the running costs for motorists buying new cars by about £500 a year by 2020.
The Government also wants to avoid the regulation creating competitive imbalance between different types of car manufacturers, and welcomes provisions in the EU proposals for setting different targets for manufacturers producing small numbers of cars.
A provision in the regulation for niche manufacturers who produce a narrow range of cars is also being urged by the UK.
