A new runway for London's Heathrow airport designed by architecture firm Grimshaw could go ahead after a ruling against it was overturned by the UK's top court.
The third runway at Heathrow was blocked in a landmark case earlier this year, when the court of appeal agreed that expanding the airport would jeopardise the country's commitment to the Paris Agreement to limit global warming.
Supreme court overturns ruling
However on 16 December 2020, the supreme court overturned the decision, allowing Grimshaw's £14 billion expansion to proceed.
"International treaties are binding only as a matter of international law and do not have an effect in domestic law," ruled the judges.

"This will also require the government to reaffirm its Airports National Policy Statement (ANPS) to help our aviation sector plan for the future of air travel to link British people and goods to the rest of the world," he added.
"Grimshaw is ready to help design this future when required."
The architecture firm has plans to build a "world-class sustainable airport", featuring a glass terminal building filled with trees.
