The European Commission has announced that 2013 is the ‘Year of Air’ with key European air pollution legislation up for review. The review represents a tremendous opportunity to improve public health by tightening air quality standards. Clean Air in London (CAL) believes that key outcomes from the ‘Year of Air’ must include continuity and the further tightening of health and legal protections. Increasing ‘flexibility’ in air pollution laws would weaken existing health and legal protections and is therefore unacceptable. There is a consultation by the EC, on options for the revision of the EU Thematic Strategy on air pollution and related policies, with the closing date on 4 March 2013. Heathrow is a major contributor to air pollution in West London, both from the airport itself and associated road traffic. Information from Hillingdon Council showed a clear correlation between the number of air transport movements and the levels of NOx.
