The EU has adopted ambitious new targets to curb climate change, with a pledge to make them legally binding.
Under a new law agreed between member states and the EU Parliament, the bloc will cut carbon emissions by at least 55% by 2030, compared to 1990 levels.
The EU parliament had pushed for a higher target of a 60% reduction.
"Our political commitment to becoming the first climate neutral continent by 2050 is now also a legal one," said EU Commission chief Ursula von der Leyen.
"The Climate Law sets the EU on a green path for a generation."
The deal comes ahead of a virtual summit of world leaders later this week, where the US is expected to announce its own climate targets for 2030.
