The transport secretary has urged campaigners not to delay the expansion of Heathrow airport.
Chris Grayling has claimed the project is "vital" and will provide a "massive economic boost" to the UK after High Court judges rejected a joint legal challenge against plans for a third runway.
A number of those challenging the development have vowed to fight their cause and continue their opposition.
Mr Grayling said: "I now call on all public bodies not to waste any more taxpayers' money or seek to further delay this vital project which will benefit every corner of the United Kingdom."
The challenges were brought forward by a group of councils, residents, Mayor of London Sadiq Khan and environmental charities including Friends of the Earth, Greenpeace and Plan B.
Friends of the Earth chief executive, Craig Bennett, said the charity now plans to appeal the ruling and fight the expansion.
Mr Bennett said: "Expanding Heathrow is wrong on every level and we can't let it go.
"I could not sleep at night if Friends of the Earth did not challenge this decision. We are going to appeal because we believe the court got it wrong.
"We are in an ecological and climate emergency and Parliament have supported an outdated decision to chase climate-wrecking development."
