Joe Biden’s win in the US Presidential election is part of a run of good news for the Global Climate. Biden has promised to rejoin the Paris Agreement on his first day in office.
The US is then required to commit a Nationally Determined Contributions (NDCs) to reductions in carbon emissions. Biden has already announced that he is committed to achieving zero net emissions by 2050, and this, along with an interim 2030 target will presumably be the basis of the US NDC.
Net zero by 2050 is now the international norm.
