The number of methane "super-emitters" detected by a satellite company has surged by approximately one-third over the past year, despite pledges from fossil fuel companies to reduce their emissions of the highly potent greenhouse gas.
Stephane Germain, the CEO of methane-tracking company
GHGSat, toldThe Associated Press on Thursday that company satellites had detected around 20,000 oil and gas operations, coal mines, and landfills that spewed 220 pounds of methane per hour since the end of 2023—up from around 15,000 the year before.
"The past year, we've detected more emissions than ever before," Germain said, adding that existing data on methane emissions is only "scratching the surface" of the reality.
"The only safe and effective way to 'clean up' fossil fuel pollution is to phase out fossil fuels."
GHGSat's data covers the period since 50 fossil fuel companies pledged to end flaring and reduce methane emissions from their operations to "near zero" by 2030 at the United Nations Climate Change Conference, or COP28, in Dubai.
At the time, more than 320 civil society organizations criticized the pledge and other voluntary commitments as a "dangerous distraction."
"The only safe and effective way to 'clean up' fossil fuel pollution is to phase out fossil fuels," the groups wrote in an open letter. "Methane emissions and gas flaring are symptoms of a more than century-long legacy of wasteful, destructive practices that are routine in the oil and gas industry as it pursues massive profits without regard for the consequences."
"That the industry, at this crucial moment in the climate emergency, is offering to clean up its mess around the edges in lieu of the rapid oil and gas phaseout that is needed is an insult to the billions impacted both by climate change and the industry's appalling legacy of pollution and community health impacts," they continued.
Yet now it seems as if the industry isn't even attempting to clean up its mess around the edges.
Germain, who is sharing his company's data ahead of the next round of climate talks at COP29 in Baku, Azerbaijan, said that nearly half of the methane super-emitters GHGSat detected were oil-and-gas related. Another third were landfills or waste facilities, and 16% from mining. Geographically, most of the super-emitting sites are in North America and Eurasia.
The data comes amid growing concerns about the extent of methane emissions and how they threaten efforts to rapidly reduce greenhouse gas pollution this decade and limit global temperature rise to 1.5°C. Methane is a more powerful greenhouse gas than carbon dioxide—with about 80 times its heat-trapping potential over its first 20 years in the atmosphere—but it also dissipates much more quickly. This means that curbing methane emissions could be an effective near-term part of halting temperature rise.
However, a series of studies published this year show these emissions moving in the wrong direction. A Nature analysis concluded in March that U.S. oil and gas operations were emitting around three times the methane that the U.S. government thought. A Frontiers of Science paper in July found that the growth rate of atmospheric methane concentrations had seen an "abrupt and rapid increase" in the early 2020s, due largely to the fossil fuel industry as well as releases from tropical wetlands.
The danger of methane emissions is one reason that the climate movement has mobilized to stop the buildout of liquefied natural gas (LNG) infrastructure, as methane routinely leaks in the process of drilling for and transporting the fuel. A September study found that, despite industry claims it could act as a bridge fuel, LNG actually has a 33%. greater greenhouse gas footprint than coal when its entire lifecycle is taken into account.
The fate of the LNG buildout, at least in the U.S., could be decided by the outcome of the 2024 presidential election. The Biden-Harris administration paused the approval of new LNG exports while the Department of Energy considers the latest climate science. While a Trump-appointed judge then halted the pause, this does not actually stop the DOE from continuing its analysis. A second Trump administration, however, would be almost guaranteed not look further into the risk of methane emissions before it approves more LNG exports. Former President Donald Trump has promised to "drill, baby, drill" and offered a policy wishlist to fossil fuel executives who back his campaign.
A document leaked in October showed that a major oil and gas trade association had drafted plans for a second Trump administration, including ending Biden administration regulations to curb methane emissions, such as an emissions fee.
As Mattea Mrkusic, a senior energy transition policy lead at Evergreen Action, warned, "Under Trump, we could double down on even more dirty fossil fuel infrastructure that'll lock us into harmful pollution for decades to come."
