Environmental groups manage to conceal the project in 2019.

Activist groups like Plan B Earth, Greenpeace and Friends of the Earth challenged the government, arguing that expanding Heathrow would be illegal because it contradicted the UK's commitment to the 2016 Paris agreement to limit global warming to 1.5 degrees Celsius.

The project was canceled in a landmark case earlier this year (2020). When the appeals court agreed that the airport expansion would jeopardize the UK's commitment to the Paris Agreement.

In this case, it is striking given that the infrastructure itself will not increase CO2 emissions but rather the increase in air traffic will be the source of pollution. The ruling established jurisprudence, as Grimshaw's project complied with all British and European environmental regulations. It was the first time that an infrastructure project had been blocked for contravening an international agreement against climate change.

The Supreme Court annuls the ruling that canceled the expansion of Heathrow airport.

However, on 16 December 2020, the supreme court overturned the decision, allowing Heathrow's £ 14bn expansion to continue. The Heathrow airport expansion could go ahead after nearly a year of litigation.
