Democrats have turned to an obscure procedural tool in an attempt to undo the Trump administrations rollback of an Obama-era regulation on methane, a potent greenhouse gas released by oil and gas operations.

In a letter Thursday to colleagues detailing upcoming agenda priorities, Senate Majority Leader Chuck Schumer (D-N.Y.) noted that Democrats plan to vote on a Congressional Review Act resolution to reinstate the Obama administrations methane waste rules.

Methane standards are one of the most important ways to address an important source of greenhouse gas emissions that contribute significantly to climate change, and the Trump administrations weakening of those standards was a dagger in the heart of efforts to address the climate crisis, Schumer said in a statement. This CRA is just one of many initiatives the Senate Democratic Majority will undertake to address the climate crisis.

The Congressional Review Act is a 1996 law that gives Congress the power to nullify any major regulation finalized within the final 60 legislative days of a presidents term. All that is required is a simple majority vote. In 2017, Republican lawmakers invoked it to scrap more than a dozen Obama-era regulations.

Sens. Martin Heinrich (D-N.M.), Angus King (I-Maine) and others introduced a joint resolution Thursday to overturn President Donald Trump s 2020 rollback , and a companion resolution is slated to be introduced in the House on Friday.

The move is critical to confronting the climate crisis and reducing harmful air pollution, Heinrich tweeted .
