Heathrow's third runway might never get built.
The Climate Change Act 2008 promised to ensure that the net UK carbon account for all six Kyoto greenhouse gases for the year 2050 is at least 80% lower than the 1990 baseline, that was following amendments.
In 2016 the UK ratified the Paris Agreement, COP25, and in 2017 promised to introduce legislation or and amendment to the 2008 Act, to go further.
In June 2018 the government won a key vote in the Commons by 415 votes to 119 - a majority of 296 to build Heathrow's third runway.
In June 2019 the government introduced a private member's bill (Rachel Reeves), as per the promise made in 2017, to reduce them to zero by 2050, but hopefully by 2030. The Bill failed to complete its passage through Parliament before the end of the session due to May's resignation and the general election, but the pledge was there.
Today the Appeal Court ruled that the government had not followed its own policy and promises when backing the controversial expansion plans. It said that the government had a duty to take into account the Paris agreement, but failed to do so. And that it was "legally fatal" to the government's Heathrow expansion policy that it did not take those climate commitments into account.
Ooops!
