The decision this week, in R (oao Friends of the Earth & others) v Heathrow Airport, sets the scene for a showdown between the airport and climate change campaigners. The decision was made by Lords Reed, Hodge and Sales. No date has yet been set for the hearing.
The Court of Appeal held in February that the government’s Airports National Policy Statement allowing the third runway to go ahead failed to take account of the UK’s responsibilities under the Paris Agreement on climate change.
The Paris Agreement, which the UK ratified in 2016, enshrined an aspiration to achieve net zero emissions of greenhouse gases.
