The Euro 5 proposal is similar to the draft posted earlier this year. Under the proposal, particulate emissions from diesel cars would be slashed by 80% and nitrogen oxides (NOx) by 20%. The tougher standards proposed would lead to the introduction of particulate filters for diesel cars. For gasoline cars, the Commission proposes to cut NOx emissions and hydrocarbons by 25%.
The Euro 5 proposal would also remove an exemption that enabled heavy passenger vehicles (such as SUVs) with a maximum mass of over 2,500kg to be approved using the less rigorous emission standards of light commercial vehicles, rather than passenger vehicles.
