Monitoring Methane Emissions: Addressing Climate Change
Members of Congress should reintroduce and support the Methane Emissions Mitigation Research and Development Act, ensuring that it addresses three critical research needs:
- Expand spectroscopic databases to support methane sensing
- Improve measurement of fuel tracers (carbon isotopes, ethane)
- Develop high efficiency detectors to support Lidar
Methane Emissions from Oil and Gas: Key Climate Change Contributor
Methane (CH4) is the second-most abundant anthropogenic greenhouse gas and significantly contributes to global warming.

Although the challenge of reducing methane emissions can be daunting, the results from aerial monitoring show that with a technology and data-driven approach, operators can significantly reduce emissions while simultaneously reducing costs and improving operational efficiency.

Opportunity For Impactful Action
Methane emissions from oil and gas production are localized, intermittent, and dominated by a relatively small number of super-emitters: less than 10% of sources of methane in oil and gas operations contribute more than half of the emissions in the sector.
Current Monitoring Capabilities Are Ineffective
- Current methane monitoring systematically underestimates emissions by up to a factor of three.
- There are no calibration standards that allow for comparison or aggregation of observations from different tools.
- There is no national repository of methane emissions observations to enable future effective monitoring and verification of reduction targets.
A National Approach is Needed for Effective Methane Emissions Reduction
- Decisive actions have both short- and long-term benefits, increasing efficiency of the oil and gas industry and mitigating climate change.
- The ability to accurately measure and monitor methane emissions is critical for any strategy that addresses climate change, including the Global Methane Pledge launched at COP26 in 2021.
