Responding to comments by business secretary John Hutton indicating strong government support for a third runway at Heathrow, the head of Greenpeace's climate campaign Robin Oakley said:

"It seems John Hutton is incapable of opening his mouth without saying something disastrous for the fight against climate change. We can beat global warming, but not by almost doubling the size of the world's biggest international airport. Environmentalists and local residents are of one voice on Heathrow expansion, this new runway cannot and will not be built."

Five Greenpeace volunteers who occupied the top of a British Airways passenger jet were today convicted at Uxbridge magistrates court.

The campaigners pleaded guilty to being in a restricted zone, boarding an aircraft and demonstrating in an airport. They were each given an 18 month conditional discharge and will pay compensation to BA totalling £5,700.

The five hit the headlines across the world in February when they walked through an open door at Terminal 1 and occupied the fuselage of the BA Airbus for two hours, hanging a banner from the tailfin reading: ‘CLIMATE EMERGENCY - NO 3rd RUNWAY'.

Anna Jones, Sarah Shoraka, Paul Della-Rocca, Frank Hewetson and Jens Loewe were protesting against Labour's plans to build a third runway and sixth terminal at Heathrow. The plane they scaled had just arrived for Manchester - a journey covered by the train in just over two hours - and was refuelling for another domestic flight. The five waited until all the passengers had disembarked before walking through an open door and going ‘airside'.

A widely derided government consultation into Labour's Heathrow proposals was completed the week of the Greenpeace occupation. Ministers are expected to announce a decision on the proposed expansion later this year.

One of the protesters, Anna Jones, said: "Climate change can be beaten, but not by almost doubling the size of the world's biggest international airport. That's why we occupied the top of BA's Manchester to London flight. A huge number of planes leave Heathrow every day destined for cities easily reachable by train. If we invested in high speed rail instead of climate-wrecking runways we could begin to reduce the environmental impact of Heathrow instead of increasing it."

The most popular destination from Heathrow is Paris, with sixty flights back and forth every day. Flights between Heathrow and locations easily accessible by train - such as Paris, Brussels, Edinburgh, Newcastle, Leeds/Bradford and Durham - total over 100,000 flights a year.

Flying is the fastest growing source of greenhouse gas emissions in the UK, doubling in the 1990s. According to the government, flights from and within the UK account for 13% of the UK's climate impact because greenhouse gases create more global warming when emitted at altitude.

British flyers already create far more carbon emissions per head than those from any other country - nearly 40% higher than the second placed country, Ireland, and more than twice as much as Americans. The Tyndall climate research centre calculates that if aviation expands as projected, Britain will have to totally decarbonise the rest of its economy by 2050 to effectively tackle climate change.

Sarah Shoraka, another of the protesters, said: "The fight against Heathrow expansion is only just beginning. This new runway cannot and will not be built."

The government is expected to launch its long-awaited consultation on expansion at Heathrow on Thursday 22 November. Airport owners British Airports Authority (BAA) want to build a new runway and a sixth terminal.

Through the Freedom of Information Act Greenpeace has obtained documents which reveal worryingly close links between the airport authority and the Department of Transport, working together to influence the outcome of the consultation:

• Extraordinary collusion between BAA and the government. They have set up a joint body - the Heathrow Delivery Group - aimed at steering the plans through the consultation process.

• BAA officials have written parts of the consultation.

• BAA supplied the data for calculations of noise and pollution that inform the premise of the consultation document. Opposition groups have not been permitted to challenge the data.

• The Department for Transport and BAA have drawn up a 'risk list' - a list of threats to the building of the 3rd runway. The list includes the 2M campaign, the group comprising councils representing 2 million people that is opposed to the plans.
