FACTBOX: EU agrees provisional deal to cut car emissions

BRUSSELS (Reuters) - The European Union has struck a provisional deal on cutting greenhouse gas emissions from cars in the battle against climate change. Here are some of the details, according to sources in the negotiations.

* Carbon dioxide emissions from new cars will be cut to 130 grams per kilometer, from a current EU-wide average of 158 grams, in a phased approach starting in 2012 and with full compliance by 2015. A further 10 grams of cuts will be achieved through external measures such as biofuels and better tires.

* Each car manufacturer must ensure that 65 percent of its car fleet complies by 2012, with 75 percent compliance in 2013, 80 percent compliance in 2014 and 100 percent in 2015.

* Until 2018, manufacturers that overshoot their targets will be fined 5 euros ($6.30) per car for the first gram of deviation, 15 euros for the second and 25 euros for the third. Above 3 grams of overshoot, carmakers will be fined 95 euros for each gram of excess. After 2018, fines of 95 euros per car will be applied across the board.

* Most of the emissions cuts must be achieved through engine improvements, gearbox improvements and reducing weight, but 7 grams can be achieved through energy-saving "eco-innovations," such as solar panels on car roofs.

* By 2020, emissions must be cut to an average of 95 grams per kilometer. A review in 2014 will determine how tightly the target will be defined, and whether factors such as biofuels will be included or excluded.
