A new study from Johns Hopkins University reveals that methane emissions from the U.S. oil and gas sector remained steady despite a surge in production and heightened regulations. The research, published in Nature Communications Earth & Environment, suggests that companies have invested in infrastructure to capture methane, a key component of natural gas, for sale as fuel, which provides a financial incentive to reduce emissions.
Scot Miller, an associate professor of environmental health and engineering at Johns Hopkins, described the findings as a 'good news/bad news situation.' While emissions did not increase as feared, there is no evidence that recent federal legislation, such as the Inflation Reduction Act of 2022, had a measurable impact on reducing methane emissions.
The study analyzed satellite data from 2019 to 2024, finding that total methane emissions from oil and gas activities ranged between 9.3 and 10.4 teragrams annually. Although emissions intensity decreased by about 11%, the overall reduction was gradual and not a significant drop. States like Texas saw a 14% decline, while California and Colorado appear to be falling short of their emissions reduction goals.
The researchers emphasized that without long-term regulatory durability, the industry may lack the incentive to further reduce methane emissions. They noted that better industry practices and less flaring have helped curb emissions intensity, but a reduction in total emissions is necessary to make a real impact.
