Controversial plans to build a second runway at Stansted Airport have been unveiled.
BAA want to double the size of the UK's third busiest airport in Essex.
If approved, the plans would see the new runway and the new terminal built by 2015, serving 68 million passengers a year by around 2030.
Announcing its planning application, BAA said the development would create more than 13,000 jobs by 2030 and boost the economy by £9 billion.
Sir Nigel Rudd, BAA chairman, said: "BAA is proud to reach the significant milestone in the future development of Stansted. We remain fully committed to building a second runway, a project that is central to Government policy in delivering additional runway capacity in the South East.
"This important project will bring huge benefits to the East of England and UK economy and will increase choice and opportunity for millions of business and leisure travellers."
The proposals have attracted fierce opposition from environmental campaigners and local residents, who claim they would ruin an area of unspoilt countryside.
The new runway and terminal would be built on 442 hectares of land and result in 13 listed buildings being lost, although 10 would be dismantled and rebuilt, BAA said.
Alastair McDermid, BAA director for Stansted Generation 2, said: "The potential benefit of a second runway is enormous for business growth, for the creation of thousands of new jobs, for supporting inward investment and for boosting inbound tourism.
"And the social and cultural benefits of even greater opportunities for leisure travel and to visit friends and family cannot be underestimated. But this is not growth at any cost. The global issue of climate change is one which we take very seriously and is recognised as requiring international action.
"There is agreement that the best way of addressing the challenge is through a global emissions trading scheme and BAA has been leading the call for the aviation industry to be part of that."
