Spain’s new government declared a national climate emergency on Tuesday, taking a formal first step toward enacting ambitious measures to fight climate change.

The declaration approved by the Cabinet says the left-of-center Socialist government will send to parliament within 100 days its proposed climate legislation. The targets coincide with those of the European Union, including a reduction of net carbon emissions to zero by 2050.
