Methane Alert And Response System

Methane Alert And Response System:

The Methane Alert and Response System (MARS) notified governments of 127 plumes spanning four continents and identified 1,500 plumes in its pilot stage.

  • Methane Alert and Response System is a data-to-action initiative with the mission to put open, reliable, and actionable data into the hands of individuals who can reduce methane emissions. ​
  • It was announced at the Conference of Parties (COP 27) in November 2022 and began its initial pilot phase in January 2023.
  • The pilot phase presented an opportunity for UNEP’s International Methane Emissions Observatory (IMEO)to engage with partners, countries, and operators to refine MARS processes and procedures before making data public.​
  • It uses satellites to scan the globe for major emission sources and alerts countries and companies so that they can take methane action and accelerate progress supporting the Paris Agreement and Global Methane Pledge.​
  • This initiative works in partnership with the Climate and Clean Air Coalition (CCAC) and the International Energy Agency (IEA).
