Climate activists have lost a long-running legal battle to stop a third runway at Heathrow.
The Supreme Court has overturned a previous Court of Appeal ruling in a case brought by Friends of the Earth and others against Heathrow Airport.
The court was asked to consider if the government’s failure to take into account the UK’s climate commitments rendered the planned third runway unlawful.
Tim Crosland, of the campaign group Plan B, said the original decision by former transport secretary Chris Grayling to support the expansion made a “mockery” of the government’s commitment to show international leadership in the face of a climate emergency.
