The European Union’s parliament on Wednesday backed a major plan to protect nature and fight climate change in a narrow 324-312 vote with 12 abstentions.

The plan is a key part of the EU’s European Green Deal that seeks to establish ambitious climate and biodiversity targets and make the bloc the global point of reference on all climate issues.

Despite the opposition of the legislature’s biggest group, the European People’s Party, the plan survived. The law implements a landmark agreement reached at the United Nations biodiversity conference in December, but the EU’s law does not show additional ambition.

Legislators also voted on more than 100 amendments to make the plan more flexible before a final law can be approved. EU climate czar Frans Timmermans wants the nature restoration law to be a key part of the Green Deal.
