In its second reading of the ozone directive on Wednesday 13 June, the European Parliament called for stricter rules to limit ozone levels in the ambient air. MEPs backed proposals put forward by rapporteur Chris Davies, ELDR, UK) to reduce the number of days on which ozone levels can exceed WHO recommendations to 20 instead of 25.
Ground-level ozone, or summer smog, has serious negative effects on human health, ecosystems and vegetation.
The draft ozone directive (a daughter directive of the EU's 1996 air quality framework directive) limits the amount of ground-level ozone to 120 micrograms per cubic metre. The aim is to achieve these limits by 2010. Under the Council's common position, Member States would be allowed to exceed these limits 25 times a year (the Commission had proposed 20 days).
