Stansted Airport: Carbon Emissions

Volume 476: debated on Thursday 22 May 2008

To ask the Secretary of State for Transport if she will estimate how many additional tonnes of carbon dioxide would be generated by a second runway at Stansted over its lifetime, calculated according to the methodology used to estimate additional carbon dioxide produced for a third runway at Heathrow as shown in Annex B, paragraph 2.23 of the Heathrow consultation document.

Our current forecasts of UK aviation carbon dioxide emissions were reported in “UK Air Passenger Demand and CO2 Forecasts” (November 2007), available at:

According to these forecasts, the opening of a second runway at Stansted airport in 2015 would cause carbon dioxide emissions from UK aviation from the time of opening to 2075 to rise by 135MtCO2, equivalent to 2.3MtCO2 per year on average.

The UK is continuing to press for the inclusion of aviation in the EU Emissions Trading Scheme, which under current proposals would effectively cap aviation emissions at an average level over the period 2004 to 2006. This means that any additional aviation emissions above that level would lead to no increase in total emissions when the trading scheme is established, since airlines would have to pay for the equivalent emissions reductions in other sectors.
