Emissions from modern gasoline vehicles

Over recent years, vehicle technologies have developed rapidly with significant improvements in emissions control. Exhaust catalysts were first required on European gasoline cars with the introduction of Euro 1 emissions limits in 1993, with subsequent evolution to the Euro 3 emissions limits of today and ‘nearzero’ Euro 4 limits from 2005.

The current challenge on gasoline cars is to further reduce CO₂ emissions, with vehicle manufacturers currently working towards the voluntary agreement for a European passenger car fleet average of 140 g/km CO₂ emissions by 2008.
