UNEP launches satellite-based system to detect methane emissions

The UN Environment Programme (UNEP) launched the Methane Alert and Response System (MARS) initiative to support global efforts to detect and act on major methane emissions sources. Established as part of UNEP’s International Methane Emissions Observatory strategy, MARS is a satellite-based system designed to detect emissions of methane and alert governments, companies, and operators so they can take rapid mitigation action.
