Methane Abatement Costs in the Oil and Gas Industry: Survey and Synthesis

NBER

2025.03.20

There is growing recognition of the relative importance of anthropogenic emissions of methane as a contributor to global climate change. An important source of such emissions in some countries, including the United States, is the oil and gas (O&G) sector. This points to the importance of developing understanding of the marginal abatement cost functions for methane emissions reductions. Scholars have employed a diverse set of methodologies to estimate abatement costs, including engineering cost models, econometric analysis of natural gas markets, and statistical retrospective analysis of state-level regulation. We critically summarize these approaches and synthesize their results. We find significant potential for low-cost methane abatement in the O&G sector in the United States and elsewhere, although claims of widespread negative abatement cost opportunities should be taken with a grain of salt. We also find that the potential for low-cost abatement is not without limit. Whereas it appears that cutting methane emissions in half would be relatively inexpensive, a sharp uptick in marginal abatement cost may occur when reductions exceed 60 to 80 percent below baseline levels. This threshold may change over time with technological advances in remote sensing, which can reduce abatement costs at various levels of ambition.
