Big win for climate activists, new Heathrow runway blocked

Britain's Court of Appeal on Thursday ruled in favour of green campaigners who oppose the building of a third runway at London's Heathrow airport. The court said the UK government - which in 2018 had approved the Heathrow extension - had failed to take into account its commitments to the Paris Agreement to limit climate warming. The legal action against the approval was brought by various London councils, environmental groups including Greenpeace and Friends of the Earth and London Mayor Sadiq Khan. The court ruled that then-prime minister Theresa May had given no explanation of how it took into account the 2015 Paris accord, which seeks to cap climate warming to less than two degrees Celsius.
