To ask the Secretary of State for Transport what economic modelling he has undertaken of the impact of (a) different oil prices, (b) emissions trading, (c) an emissions charge and (d) an increase in air passenger duty on the growth of aviation greenhouse gas emissions.
Karen Buck (Parliamentary Under-Secretary, Department for Transport; Regent's Park and Kensington North, Labour)
Our forecasts for aviation and climate change, and the assumptions underlying them, are set out in Aviation and Global Warming", published by the Department for Transport in January 2004. The best case" scenario emissions forecasts assumed the introduction of economic instruments to tackle climate change, resulting in improved fuel efficiency. We have not undertaken analysis to consider these specific scenarios.
