To ask the Secretary of State for Transport by what amount emissions trading is expected to reduce the Government's forecast of increased climate change emissions from aviation at 2030, expressed as a percentage and in absolute terms.
Karen Buck (Regent's Park and Kensington North, Labour)
At present, it is too early to provide a reliable estimate of the impact emissions trading will have on forecasts of emissions from aviation. This will depend on a number of factors including the overall number of allowances and the detailed design for the inclusion of aviation into the ED ETS. These factors have yet to be specified and will be subject to discussion with other member states' Governments.
