Dept for Transport

Question: To ask the Secretary of State for Environment, Food and Rural Affairs, what the projected improvement is in emissions from aircraft engines over the next 25 years on which government predictions of emissions are based.

Answer: Mrs. May: To ask the Secretary of State for Environment, Food and Rural Affairs what the projected improvement is in emissions from aircraft engines over the next 25 years on which Government predictions of emissions are based. [195088] Charlotte Atkins: I have been asked to reply. In February 2004, the Government published technical reports in support of the Air Transport White Paper that include projections of improvement in aircraft engine emissions. The report "Aviation and Global Warming" includes assessments of fleet renewal, fuel efficiency improvement and emissions improvement. The report Air Quality Assessments Supporting the Government's White Paper "The Future of Air Transport" focuses more on prospects for engine improvements in emissions of oxide of nitrogen (NOX ). Technology projections relate to different timescales up to 2030 and span a range of emissions performance given uncertainty over proving technologies and bringing them to market. These technical reports are available at www.aviation.dft.gov.uk
