A brand new satellite tv for pc that launched at this time is designed to search out methane leaks wherever on this planet—and might be a robust device within the battle in opposition to international warming.
Methane is stronger than CO2 within the brief time period, with round 80 occasions extra warming energy. And whereas CO2 can final centuries, methane lasts solely round 12 years. Making huge cuts in methane emissions can have an outsize impression. “It’s a possibility over the subsequent couple many years to gradual issues down,” Steven Hamburg, venture lead for MethaneSAT, the brand new satellite tv for pc, mentioned at a press convention.
Oil and fuel firms are one of many greatest sources of the issue and had been liable for round 135 million tons of methane emissions final 12 months. The fixes are sometimes low-cost and straightforward; when there’s a leak, firms would possibly simply have to interchange a damaged valve or seal.

New rules within the U.S., set to be launched later this week, would require the fossil gas trade to slash methane emissions. China and the EU are additionally working to rein within the emissions. Greater than 50 oil and fuel firms additionally just lately pledged to just about remove methane emissions by the tip of the last decade.

The brand new satellite tv for pc, which can share its information publicly, will help firms rapidly establish leaks whereas additionally serving to governments and activists maintain polluters accountable. (The info received’t be accessible instantly, however the platform will ramp up all year long.) Previously, oil and fuel firms have self-reported their methane emissions based mostly on engineering calculations. However analysis confirmed that precise emissions within the U.S. are round 60% larger than what firms reported.

The venture spun out of the Environmental Protection Fund (EDF), which has been monitoring methane emissions from the oil and fuel trade for greater than a decade utilizing planes, drones, and different instruments. A number of other satellites are additionally monitoring methane emissions now, however they search for giant leaks or simply observe the general degree of methane within the environment. EDF labored with scientists at Harvard to make the brand new satellite tv for pc able to monitoring each giant and small emissions over a big space, and pinpointing the sources.
Contained in the satellite tv for pc, roughly the dimensions of a washer, spectrometers level down on the Earth and detect methane molecules in mirrored daylight. Google partnered on the venture to make use of AI to map international oil and fuel infrastructure, and can share information from the satellite tv for pc on Google Earth Engine. The satellite tv for pc will also be used to search out methane emissions at different sources, together with landfills.
If oil and fuel firms act rapidly, the impression might be vital: EDF has calculated that it’s doable for the trade to chop methane emissions in half by 2030, which may minimize the speed of world warming over the subsequent few many years by greater than 25%.
