The 27 members of the European Union agreed on Dec. 11, after a night of negotiations, to reduce by at least 55 percent their greenhouse gas emissions by 2030, compared with 1990 levels, increasing the target from a previous objective of 40 percent.

“Europe will reduce emissions by at least 55% by 2030. It puts us on a clear path towards climate neutrality in 2050,” wrote Ursula von der Leyen, President of the European Commission on her Twitter account.
