This White Paper sets out a strategic policy framework for the development of airport capacity in the UK over the next 30 years. Chapters focus on the following: the strategic framework; the environmental impacts; the air transport sector. It also looks at individual regions and the impact for them, including: Scotland, Wales and Northern Ireland, also the North of England, the Midlands, the South West and finally the South East. The framework itself can be used by public bodies, air operators and airlines for future planning applications. It also sets out the Government and devolved administrations' conclusions on the case for future airport expansion, taking into account the large consultation exercise of over half million respondents. This paper provides reasons why airport capacity should be expanded, but recommends a balanced approach to the issue. Among the reasons are: the economic importance of air travel for the country’s economy and the increased desire amongst the population for foreign travel, which should be balanced against minimizing, where possible the environmental effects to an area where airports are situated. These are some of the main cases for future development following a full environmental assessment: for Scotland: an additional runway at Edinburgh Airport; substantial terminal development at Glasgow Airport. For Wales: further terminal development needed at Cardiff airport. For Northern Ireland: development of increased capacity at Belfast. For the North of England: additional terminal capacity provided at Manchester Airport and development of increased capacity at Liverpool John Lennon Airport. For the Midlands: additional runway for Birmingham. For South West England: expansion of Bristol Airport. For South East England: a new runway at Stansted; further development of Heathrow supported, including a further runway and additional terminal capacity. Some options though are not to be followed through, including: two new runways at Gatwick, a development of a second runway at Luton, and a new airport at Cliffe, a new airport of central Scotland, and a new airport at Rugby.
