Satellite To 'Name and Shame' Worst Oil and Gas Methane Polluters
MethaneSat will provide the first near-comprehensive global view of leaks of the potent greenhouse gas from the oil and gas sector, and all of the data will be made public. It will provide high-resolution data over wider areas than existing satellites. Methane, also called natural gas, is responsible for 30% of the global heating driving the climate crisis. Leaks from the fossil fuel industry are a major source of human-caused emissions and stemming these is the fastest single way to curb temperature rises.
MethaneSat was developed by the Environmental Defense Fund, a US NGO, in partnership with the New Zealand Space Agency and cost $88m to build and launch. Earlier EDF measurements from planes show methane emissions were 60% higher than calculated estimates published by US authorities and elsewhere. More than 150 countries have signed a global methane pledge to cut their emissions of the gas by 30% from 2020 levels by 2030. Some oil and gas companies have made similar pledges, and new regulations to limit methane leaks are being worked on in the US, EU, Japan and South Korea.
The EDF's senior vice-president, Mark Brownstein, said: "MethaneSat is a tool for accountability . I'm sure many people think this could be used to name and shame companies who are poor emissions performers, and that's true. But [it] can [also] help document progress that leading companies are making in reducing their emissions." The oil and gas industry knows how to stop leaks and the cost of doing so is usually very modest, said Steven Hamburg, the EDF's chief scientist and MethaneSat project leader: "Some call it low hanging fruit. I like to call it fruit lying on the ground."
