New satellite to spot planet-warming industrial methane leaks

Multimillion dollar project will scan and make public methane leaks from oil and gas plants that are a major contributor to global warming

Methane leaking from oil and gas facilities around the world - a major contributor to global warming - is set to be spotted from space.

The Environmental Defense Fund (EDF) has announced it aims to launch a satellite called MethaneSAT by 2021 to scan the globe and make major leaks public. That information will then enable governments to force action, EDF hopes. Building and launching the satellite will cost tens of millions of dollars, but EDF says it has already raised most of the money.
