In a revealing look at the once-celebrated role of natural gas as a "clean" bridge fuel, the International Energy Agency (IEA) 2024 methane tracker has spotlighted the United States as the leading emitter of methane from oil and gas industries globally. All use of methane is now under scrutiny and what's being discovered isn't good.

The USA's 'leadership' isn't surprising given the country's ascendance to being the world’s largest oil producer, significantly outpacing countries like Saudi Arabia. With methane's global warming potential dramatically outpacing that of carbon dioxide over the short term, the emissions from the U.S. alone account for a significant portion of global greenhouse gases, 1% to 3% of global carbon dioxide annual emissions, challenging the narrative of natural gas as an environmentally friendly alternative and the USA's claims to being an emissions reduction leader.
This revelation is not new to experts like Robert Howarth of Cornell University, who has long testified about the U.S.'s outsized methane emissions.
Further complicating the issue, the shipping industry's shift towards LNG as a fuel because it's lower emissions has been called into question by the The International Council on Clean Transportation FUMES study. The study found that methane slip from the most common ship engines it's used in is higher than expected, 6.4% instead of 3.5%, rendering natural gas worse for the climate than traditional maritime fuels.
The practice of flaring, intended to reduce methane emissions from oil and gas production, has proven less effective and more harmful than previously thought, with issues ranging from poor maintenance of flare stacks to adverse health impacts on nearby communities. Workers in some cases were not flaring but simply venting methane due to complaints from neighbors.
The dialogue on reducing methane emissions has gained momentum with initiatives like the Oil & Gas Methane Partnership 2.0, encouraging accurate reporting and reduction efforts within the industry. Yet, as companies begin to measure their actual emissions, they inevitably find them significantly higher than anticipated and not where modeling predicted they would be, suggesting a long road ahead in addressing methane's climate impact. And OGMP 2.0 covers only a fraction of the oil and gas industry at present.
Shell in Canada found that the stationary methane engines used to power their facilities were slipping methane at a much higher rate than expected. Their answer? Replace them with electric motors and stop burning their own product for energy.
