The Climate and Clean Air Coalition (CCAC), Environmental Defense Fund (EDF), Oil and Gas Climate Initiative (OGCI) and European Commission are working together on a series of peer-reviewed scientific studies to measure methane emissions in the oil and gas sector. The data collected will help companies and governments prioritize actions and policies to reduce methane emissions.
Methane is a greenhouse gas many times more powerful at warming the atmosphere than carbon dioxide. However, relatively little is known about emissions from one of its largest man-made sources, the oil and gas industry.
The International Energy Agency has noted that “the potential for natural gas to play a credible role in the transition to a decarbonized energy system fundamentally depends on minimizing methane emissions, particularly outside the U.S.”
Most of what we do know concerns methane emissions in the United States, where oil and gas production is booming and where EDF carried out 16 studies in cooperation with the industry that led to 28 peer-reviewed papers on US emissions. Outside the US, however, emission estimates are less certain. The new studies will help refine the global estimates that do exist while improving national estimates.
The new global study comes out of an announcement made by EDF and several oil and gas companies in 2015 at COP21 in Paris to better quantify the industry’s contribution to global methane emissions across the value chain. Since then, Phase-1 work has focused on understanding what data gaps exist and what additional science would be most effective in filling those gaps. Phase 2, which started in 2018, consists of field studies using multiple measurement methods.
The studies are governed by a Steering Committee of funders. The science will be guided by a Scientific Advisory Panel and Chief Scientist, Steven Hamburg of the Environmental Defense Fund. The governance protocols for the studies will build on the model and experience of the EDF-led studies in the US, aimed at ensuring scientific integrity. This includes measures to safeguard researchers’ independence and publication of the studies in peer-reviewed journals.
The Coalition, whose Secretariat is hosted by UN Environment, has made this new science initiative an official part of its work. This will allow the study to take advantage of synergies with the CCAC Oil & Gas Methane Partnership, a public-private voluntary initiative that helps oil and gas companies take a systematic approach to reducing emissions and reporting on progress. For example, some studies could build on the field surveys that some companies are carrying out under the Oil & Gas Methane Partnership.
Over $7 million in donations have been received from the European Commission, EDF, and the companies of the Oil and Gas Climate Initiative (OGCI). Other companies and CCAC Partner governments are invited to provide additional funding to the studies to help expand their scope.
Additional companies, governments or other organisations interested in contributing to the studies should contact the activity coordinators.
Two papers of the CCAC Methane Studies have been published first half of 2020: “Methane Emissions from Offshore Oil and Gas Platforms in the Gulf of Mexico” and “Airborne Assessment of Methane Emissions from Offshore Platforms in the U.S. Gulf of Mexico”.
Shipboard measurements of offshore oil and gas facilities were conducted in the Gulf of Mexico in February 2018. Species measured at 1 s include methane, ethane, carbon-13 (13C) and deuterium (D)...
Methane (CH4) emissions from oil and gas activities are large and poorly quantified, with onshore studies showing systematic inventory underestimates. We present aircraft measurements of CH4...
