Airport Pollution

29 May 2015

Airport expansion at Gatwick would cause:

  • A huge increase in aircraft movements with a tenfold increase in freight (not fully assessed by the Commission) 
  • 100,000 extra vehicles on the roads per day around Gatwick when it’s running at full capacity (which the consultation does not take fully into account)[i]
  • Air quality worsened at 21,000 properties (in terms of annual NO2 mean concentrations) according to the Commission 

Surrey already has the worst incidence of deaths caused by air pollution in the South East[ii].  Clean Air London says the increases in air pollution around Gatwick would be in breach of the UK’s Sustainable Development duties under European law[iii].


At Heathrow, airport expansion would cause:

  • Further breaches in compliance with EU limits on NO2 emissions (despite the UK already being the subject of legal processes to address this). Worsening air quality further would be illegal[iv]
  • Poorer air quality at up to 47,000 properties (depending on which scheme is chosen)

The UK already has the highest proportion of zones exceeding safe NO2 limits in Europe.


Green Party MEP for the South East, Keith Taylor, said:

“Sir Howard Davies could hold 100 consultations if he wanted but the reality is that building any major new runways would be seriously bad news for air quality, rule out any chance of meeting our climate change targets, and would result in an unprecedented increase in noise levels. My preference in this polarised `Heathrow or Gatwick` debate is for neither to be allowed. Expansion of either makes their environmental impact worse. We can, and should avoid them both”.

Jacquetta Fewster of Mole Valley Green Party said:

“We need a Strategic Environmental Assessment of these proposals. It’s not a localised issue and the impacts will be widely felt and need to be assessed more broadly”.

Jonathan Essex Chair of South East Green Party, and Reigate and Surrey councillor, said:

“The biggest impact here is climate change, and international flights are not currently included in UK carbon targets. If we properly account for climate change we won’t expand our airports. There should be a further consultation on climate change too”.

The Green Party – alongside other groups including Clean Air London and the Gatwick Area Conservation Campaign – is telling the Commission that its assessments totally underestimate future impacts as they are for 2030 when the expanded airports would only be at half capacity. But even the increases in pollution it has identified would be illegal and damaging to human health.
