The European Aviation Safety Agency (EASA) have said that helicopter engine emissions are contributing to poor local air quality and may be considered problematic in certain cities. The evidence shows that the air quality impact of helicopter engine emissions is localised, meaning that helicopter movements in central London are likely to have a significant impact on nearby air quality. It seems unfair that private helicopters flying into central London should not be subject to the same engine emissions regulations, and Congestion Zone Clean Air charge, as cars and commercial vehicles as helicopters emit more pollutants than any typical car. Will you investigate the feasibility of a T charge or equivalent for private helicopters?

I am concerned that too many helicopters fly over London.  Overall aviation emissions, including aeroplanes and helicopters, account for around 10 per cent of NOx and 1 per cent of Particulate Matter. A great many Londoners also suffer from the noise from helicopters over the city.

In the draft London Plan (Aviation: Policy T8-J), I call for steps to be taken to reduce helicopters overflying London. However, my powers over the regulation of helicopters are severely limited. This is the responsibility of the CAA, who so far have been unwilling to review the outdated regulations that govern helicopter flights over London. I will be calling on them to reconsider and develop a regulatory regime for helicopters that better reflects their environmental impacts on Londoners.
