Ms Buck: There are no plans for an access road for Canvey Island for use during the 2012 London Olympic games, as it does not currently feature in Olympic plans as a venue and is not likely to be subject to significant additional traffic due to the Olympics.
Ms Buck: None. The Future of Air Transport White Paper stated that air travel had increased five-fold over the past 30 years, and demand was projected to be between two and three times the current levels by 2030. There were no specific figures for Buckinghamshire or any other part of the UK.
Mr. Lidington: To ask the Secretary of State for Transport what estimate he has made of the likely future trend in (a) the number of aircraft flights and (b) level of aircraft noise over Buckinghamshire during the next 10 years. 
Ms Buck: The Department has recently agreed to support an application from the Welsh Assembly Government (WAG) for a public service obligation (PSO) to be placed on a new air route between Cardiff and RAF Valley on Anglesey.
Ms Buck: The imposition of public service obligations (PSOs) is governed by European legislation laid out in Regulation 2408/92. This regulation sets out a number of criteria which must be met in order for a PSO to be imposed.
Applications to create a PSO are considered by the Department for Transport against these criteria. The Secretary of State then decides whether to impose a PSO on that route. The only PSOs currently in operation are in support of 15 lifeline air services to remote communities in Scotland.
Ms Buck: Southend borough council has not installed any priority bus lanes since 1997. The borough council has implemented a range of other bus priority measures including real time bus information displays at bus stops, bus priority at junctions and improved interchange facilities.
Mr. Lidington: To ask the Secretary of State for Transport what his policy is on the monitoring of the compliance of civil aircraft noise levels with international noise certification standards. 
Ms Buck: Aircraft operating into the UK have to comply with noise standards agreed through the International Civil Aviation Organisation. Compliance for those aircraft on the UK register will be verified by the Civil Aviation Authority; for non-UK aircraft it will be by the state of registry. Airports may seek information from airlines on the noise certification status of aircraft in the event of uncertainty.
The Government support the use of clean, low carbon fuels primarily by means of fuel duty incentives. The rationale for decisions on the level of Government support for different fuels is set out in the Alternative Fuels Framework published in the Chancellor of the Exchequer's 2003 pre-Budget report. We have also been considering whether some form of Renewable Transport Fuels Obligation might be an

appropriate means of increasing the use of renewable fuels in the transport sector. We are due to publish a detailed feasibility study on this shortly.
In addition, this Department has recently launched a new grant programme to help meet some of the additional costs of installing refuelling infrastructure for certain clean alternative fuels, the details of which are available via www.est.org.uk/fleet
For information on the use of retread tyres in vehicles provided to the Department by the Government Car and Despatch Agency I refer the hon. Member to the letter of 11 October 2005 which he received from the Chief Executive of the GCDA, reference UIN15087 and UIN15088. Copies of this letter are available in the Library.
Dr. Ladyman: There are no plans to undertake such a study. A study of the implications of changing to driving on the right was considered some time ago and was rejected on both safety and cost grounds.
Derek Twigg: Data on the nature of travel for every first class rail journey are not held centrally by the Department. We are aware that the majority of first class corporate travel takes place at the full, flexible fare. The national Rail Travel Survey to be launched by the Rail Passengers Council under the Railways Act 2005 will capture the business/leisure split in future years.
An analysis of ticket types sold in the year to August 2006 shows that 75.4 per cent. of first class travel was full open fare type, compared to 24.6 per cent. of advance purchase, Apex and other promotional fare offers.
