The proposed expansion of Heathrow and London City airports would be an environmental catastrophe. It would mean more plane noise, more pollution, more congestion on our roads. Increases in greenhouse gas emissions would make it impossible for the UK to meet even its current, inadequate commitments to address the crisis of the global rise in temperatures.

The construction of a third runway at Heathrow (in effect, a new airport adjoining the existing one) would have the most damaging environmental impact of any new infrastructure project in Britain. It will result in 750 more flights a day (280,000 a year); the destruction of around 750 homes; two new car parks with 24,000 and 22,000 parking spaces; diversions of the M25 and A4; the rerouting of local rivers; and loss of habitats at wildlife areas including Staines Moor, a Site of Special Scientific Interest. Increased disturbance from flight paths will impact Southwark residents, along with millions of people across London, including many who are not currently overflown.
