A new open letter out Monday calls for further actions to cut emissions of short-lived pollutants such as soot, methane and refrigerant gases.

Why it matters: These substances warm the climate over far shorter time periods than carbon dioxide and are key to achieving short-term climate goals.

Yes, but: Many countries don't include such pollutants in their national climate plans, and corporations are falling behind when it comes to working to cut such emissions as well, the letter states.

Zoom in: The communiqué was organized by the VC-backed company Recoolit, which focuses on cutting refrigerant emissions while expanding cooling availability, particularly in the developing world.

  • The letter has support from Project Drawdown, Terraset, and Frost Methane Labs, among others.
  • It notes the failure of many national climate plans to include short-lived climate pollutants and the need for more urgency, coordination and detailed policy agendas.

Between the lines: There has been plenty of international coordination, as well as upcoming domestic regulation, around curtailing methane emissions in recent years.
