Satellite picture1 liter gasoline/petrol - burnt in a car - emitts about 2.3 kilogramm carbon dioxyde. Diesel even more: 2.6 kg CO2. Only 10 per cent of the fuels energy are effectively used to transport you. The rest is wasted for moving iron , tires and oil.

Of course cars must be safe, but in no car you have a chance to survive a crash with 120kph. So why is it fun to drive with death speed? However if you really need your own car and car sharing is not an option, check out climate friendly cars.

ExploreOurPla.net mirrors from now the car fuel database of the Vehicle Certification Agency based in UK. 3,300 models from Alfa Romeo to Volvo all with CO2 emissions per kilometer.

The winner is the Prius build by Toyota with its hybrid engine and 104 g/km CO2. To compare: the 2001 Roadster L144 from Lamborghini emitts 520 g same distance.
