Methane Alert and Response System

May 9 , 2026 16 hrs 0 min 53 0

The United Nations (UN) expanded the Methane Alert and Response System (MARS) to include the coal and waste sectors.
The decision followed satellite data that identified the Kanjurmarg landfill in India among the world’s three largest methane-emitting landfill sites.
Other major methane-emitting landfill sites were identified in Chile.
MARS is the world’s first global satellite-based system for monitoring methane super-emitters.
The system connects satellite data with rapid methane mitigation and response efforts.
MARS functions under the International Methane Emissions Observatory (IMEO) of the United Nations Environment Programme (UNEP).
The system was announced during the 27th Conference of the Parties (COP27) and was officially launched in January 2023.
