After a night of negotiations, the European Union agreed early Wednesday to a tentative deal that would make its 27 member states climate neutral by 2050. "Our political commitment to becoming the first climate neutral continent by 2050 is now also a legal commitment," EU Commission President Ursula von der Leyen said. "The Climate Law sets the EU on a green path for a generation." As part of the preliminary agreement, the EU will also commit to slashing greenhouse gas emissions by at least 55 percent by 2030, compared to 1990 levels, The Associated Press reports. The EU's member states and legislature still have to officially sign off on the deal, but it's expected to be approved, AP says. Starting Thursday, President Biden is hosting a two-day virtual climate summit, which will be attended by dozens of world leaders.
