Britain’s highest court has ruled that government planners failed to consider the harmful effects of global heating when they approved a new oil well near London’s Gatwick Airport. It’s a major victory for environmentalists and a setback for Prime Minister Rishi Sunak, who’s pledged to “max out” the U.K.’s oil and gas reserves. Climate campaigner Sarah Finch led the legal fight against the oil well.

Sarah Finch: “In climate science, we hear a lot about tipping points, Amazon deforestation, melting permafrost, things that accelerate global warming in an unpredictable and frightening way. I think today we’ve just seen a tipping point in the other direction. No longer will any planning authority be allowed to wave through fossil fuel production without fully considering the climate impact.”
