Driving reductions in methane emissions

  • We’ve cut methane emissions intensity by more than 60% since 2016 and expect to achieve our planned reduction of 70-80% in 2026.1
  • Reducing methane leaks is smart business. Keeping more natural gas in the pipe means more to sell, and increased natural gas usage has been the biggest driver in cutting CO2 emissions from electricity generation in the U.S. in recent years.2
  • We’re continuing to expand continuous monitoring and detection of methane emissions, and we’re sharing what we learn with others. We obtained OGMP 2.0 Gold Standard Pathway recognition in 2025.

We’re deploying leading-edge technology on the ground, in the air, and in space to mitigate, monitor, and measure methane emissions. Vantage, our centralized operations and monitoring center, is giving us real-time data on methane emissions at sites across our upstream business, with more sites added all the time.

From our Model Regulatory Framework to collaborations with the U.N. Oil & Gas Methane Partnership (OGMP) 2.0 and others, we’re working to be a global leader in eliminating methane emissions. 

Methane is a powerful molecule

With just one carbon and four hydrogen atoms, methane is the principal component in natural gas. It has the high energy density needed to make natural gas a reliable and flexible energy source. Natural gas is doing more to meaningfully reduce CO2 emissions in the U.S. electricity sector than any other technology.3 It will remain a critical source of energy in a lower-emissions future. Our Global Outlook forecasts that natural gas will supply nearly 25% of the world’s power generation needs in 20504– and it can do so with approximately 60% less carbon emissions when replacing coal.5 

But, as with any form of energy, there are tradeoffs. For natural gas, fugitive or leaked methane is a challenge. Compared to CO2, methane exists for a short time in the atmosphere but has approximately 30 times the global warming potential on a 100-year timespan.6

That’s why it’s important for us to keep methane contained and managed – in our pipelines, in our storage tanks, and in our processing equipment.

Methane at ExxonMobil

Methane emissions in our industry come from four main sources:

  • Flaring: the burning of excess natural gas for safety or other reasons.
  • Venting: the release of excess methane to reduce pressure in pneumatic devices, storage tanks, dehydration units, and other components of our operations to help ensure safety.
  • Fugitive emissions: unintentional leaks from equipment.
  • Combustion slip: uncombusted methane in the exhaust of natural gas engines.

As reported in our data table, methane emissions at ExxonMobil were approximately 142,000 metric tons in 2025, about 5% of our total direct (Scope 1) operated emissions. Approximately 96% of our methane emissions come from our upstream operations.

Mitigating methane emissions

We’re taking a multilayered approach, using leading-edge technology to mitigate, monitor, and measure methane emissions.  

We start with mitigation. Because when we eliminate potential sources of routine and non-routine methane leaks, we’re also reducing uncertainty. With fewer ways for methane to leak, we can keep it contained and focus our monitoring and measurement efforts where they’re most needed.

To reduce our methane intensity, we are evolving the designs of our facilities, improving our processes and protocols, and pursuing new technologies.

Aiming for zero

In March 2022, we joined others in our industry to launch the Aiming for Zero Methane Emissions Initiative to strive to reach near zero methane emissions from operated oil and gas assets by 2030. Our efforts support the goals of the Global Methane Pledge.

In 2025, flaring made up about 15% of methane emissions in our upstream operations.12 Flaring is the most visible source of methane emissions because the flame can be seen by the naked eye. It’s also a focus area for us, which is why we’ve eliminated routine flaring in our heritage ExxonMobil operations in the Permian Basin.13 We are on track to achieve zero routine flaring across all operated upstream assets by 2030 in line with the World Bank's Zero Routine Flaring by 2030 Initiative.14

Ongoing enhancements – large and small, complex and simple, proven and leading-edge – are advancing our efforts to reduce or avoid methane emissions.

In some cases, we’re modifying designs or simply doing the same things, but better. For example, we continue to improve the seals on centrifugal compressors to prevent leaks, and we are expanding gas collection systems to capture and transport natural gas for processing. We’re also retrofitting tanks at some existing sites to reroute emissions sources through vapor recovery units, and using pressurized, closed-system vessels instead of traditional tanks in new builds.

In short, every feasible option is on the table as we work to safely and reliably mitigate methane emissions.

Certified natural gas

MiQ is a not-for-profit organization who assesses methane emissions producers, certifying more than 20% of the natural gas produced in the U.S. Since 2022, we have worked with MiQ to certify the methane intensity of our natural gas through independent, facility-level assessments. This helps our customers make more informed decisions about the GHG emissions of the natural gas they purchase. Our facilities in the Appalachia Basin and at Poker Lake, New Mexico, undergo routine recertifications. Notably, in 2025, our Poker Lake facility achieved a top grade for the fifth time.15

Replacing pneumatic devices

Pneumatic control devices have been used in our industry for more than a century. They operate valves that control liquid levels, pressure, temperature, and other parts of the production process.

They also emit methane. Each time a natural-gas-driven pneumatic device is used, a small amount of methane is vented. Multiply this by the number of devices at each site, and it can add up. That’s why we are working to eliminate natural-gas-driven pneumatic devices in our key U.S. unconventional operated assets. We have already eliminated pneumatic devices in our heritage ExxonMobil unconventional assets in our Permian Basin operations. We’re doing the same in the Pioneer assets we acquired, and we have already replaced more than 6,000. We plan to eliminate pneumatic devices across our integrated Permian Basin operations by 2030. We’re expanding this work to other sites in our U.S. operations and have eliminated more than 10,000 pneumatic devices since 2023.

Unfortunately, there’s no one-size-fits-all solution to the challenge of pneumatic devices. In some cases, when there’s ready access to electricity, it’s as simple as installing an air compressor or a mechanical valve. In other cases, it means looking outside our industry, collaborating with others to enhance existing controllers and other technologies to mitigate or eliminate emissions. It can even mean using existing equipment in new ways, such as substituting nitrogen, a gas with no global warming potential, in pneumatic devices.

And the benefits extend beyond each piece of equipment. When retrofitting our existing assets, we often replace the infrastructure, which improves reliability and can further reduce the chances of leaks and fugitive emissions.

We’re continuing to conduct trials to test emerging solutions as well. We’ll deploy the most promising ones and share what we learn to advance the ambition of near-zero methane emissions.

Setting the standard in the Permian Basin

In the Permian Basin, our production continues to grow to help meet demand. At the same time, we’re making good progress on our industry-leading plans to achieve net zero across our integrated assets by 2035 for Scope 1 and 2 GHG emissions. By 2030, we plan to reduce emissions in our combined Permian operations by more than the equivalent of achieving net zero in our heritage ExxonMobil assets. Reducing methane emissions is a key part of that plan.

Monitoring and detection

Our detection and quantification work is improving the accuracy of the methane volumes and intensity data we report. This work also helps us assess the scale of the challenge and how effective our efforts are. The framework we’ve established and shared with regulators, trade groups, and others has helped in the development of consistent and comparable data which, along with improving field measurements, guides our mitigation efforts.

On the ground, in the air, and in space, the technology and processes we use to identify non-routine methane emissions give us a wide range of data points to inform and continuously improve our mitigation efforts. At this time, we’re advancing detection technologies across our global upstream operated assets.

The technology to detect and quantify methane emissions keeps getting better. The current industry and regulatory approach on the ground is focused on manual leak detection. At the same time, we’re investing to develop and deploy technologies that increase the efficiency, precision, and real-time coverage of our detection abilities.

We are rapidly advancing the development and deployment of near-continuous monitoring, including fixed cameras and on-the-ground sensors, to enable instant notification and expedited mitigation of potential non-routine emission sources. We expect to deploy continuous monitoring on all key operated sites in the Permian Basin by the end of 2026 – including heritage ExxonMobil and heritage Pioneer assets. And we plan to do the same in our upstream key operated assets around the world by 2028.

Periodic monitoring using airplanes or drones can further expand coverage to dozens of onshore sites per day, depending on local conditions and logistics. The moment-in-time observations provided by airplane surveys continue to be a valuable source of data – but we’re overlaying this work with satellites to enhance detection across larger areas on a more continuous basis.

Beyond our own operations, we have played a leading role in advancing two major methane‑mitigation collaborations within the Oil and Gas Climate Initiative: the Satellite Monitoring Campaign and the Satellite Methane Detection Response Playbook. Analysis shows that more than 90% of the global upstream oil and gas methane emissions are from non-OGCI member companies’ operations. The monitoring campaign, developed with satellite providers, has raised industry awareness of how satellites can support methane‑reduction efforts and strengthened peer-to-peer knowledge sharing about methods to spot and track emissions. The response playbook gives both OGCI and non-OGCI operators clear steps to act quickly and manage methane emissions detected from space.

In March 2026, OGCI launched a new collaboration with the nonprofit Carbon Mapper aimed at accelerating practical and measurable reductions in methane emissions from the oil and gas industry. The collaboration combines Carbon Mapper’s publicly available satellite-based methane data, expertise, and strategic insights with OGCI’s industry-led, peer-to-peer engagement model to help operators identify, prioritize, and mitigate emissions more quickly and effectively.

Introducing Vantage: A new lens on upstream operations

In October 2025, ExxonMobil unveiled Vantage, a world-class, centralized operations and monitoring center we have been using to drive safety, environmental, and operational excellence.

Vantage is a 24/7 central hub for real-time monitoring and production management. An extension of our field teams, it helps drive safer, more efficient and more sustainable work across our upstream U.S. operations. At the heart of this effort is our Center for Operations and Methane Emissions Tracking (COMET) platform we launched in 2022. But Vantage isn’t just a control room, it’s a high-tech nerve center that’s making a real impact across ExxonMobil’s upstream operations.

In practice, that means:

  • More than 22,000 wells monitored around-the-clock, covering major regions like the Permian Basin and the Bakken.
  • More than 1 million barrels of oil per day managed and optimized.
  • More than 3 billion cubic feet of natural gas monitored and directed daily.
  • Significant emissions reductions, helping to eliminate flaring of more than 34 million cubic feet of gas in 2024-2025.
  • More than 18,000 hours of employee and contractor driving avoided in 2024-2025, improving personnel safety.

Methane monitoring through Vantage operates much like a smoke detector in your home. When the alarm sounds, you know that it has sensed a problem. Whether it’s smoke or just a low battery, you know that you need to respond. We’ve scaled the same concept to cover massive areas with diverse sources of data. When there’s a problem, our operators know.

Through Vantage, we continuously monitor and analyze methane emissions data from sources across our heritage operations in the Permian Basin – 24 hours a day, 7 days a week. This capability is a game changer for the industry, and we’re continuing to apply what we learn to new sites across our operations. 

Measurement and reporting

We’ve publicly reported our methane emissions every year since 2014. Reporting is useful as we work with academia, industry peers, and other stakeholders to improve understanding of methane emissions and develop best practices.

Our data, past and present, is measured and reported based on internationally recognized methods and is compiled by determining emissions by source at each operated asset across our company. Using frameworks like Veritas and OGMP, we’ve improved our reporting each year.

Reducing uncertainty in how we quantify methane emissions is an important part of our efforts. We’re advancing solutions that help to continuously monitor and more precisely measure methane emissions.

As technology develops, we’re making good progress with direct methane measurement, recognizing that in some cases, direct measurement and quantification may be difficult or impossible. In offshore locations, for example, water interferes with accurate satellite and aerial measurement. In other areas, airspace regulations may restrict drone use. Each location is different and presents unique challenges.

 

Oil & Gas Methane Partnership (OGMP) 2.0

We joined the United Nations' Oil & Gas Methane Partnership (OGMP) 2.0 in January 2024 and achieved Gold Standard Pathway recognition in 2025. As part of OGMP 2.0, we are performing measurements at the emission source as well as leveraging our growing network of continuous monitors. This work will contribute to a better understanding of our absolute emissions and support continuous monitoring solutions. Since joining OGMP 2.0, we have been active in sharing our best practices in methane mitigation and quantification, including presenting our learnings at the OGMP 2.0 annual conferences in 2025 and 2026.


Understanding emission factors

Consistent with industry practices, we use emission factors with observational and other data to estimate average methane emissions. Classes of equipment, types of activities, or other variables are multiplied by the relevant emission factor, which provides a credible estimate for our emissions inventory. Consistent with regulatory reporting requirements, emission factors come from multiple sources, including the American Petroleum Institute and the U.S. Environmental Protection Agency. In 2025, we updated our emissions factors consistent with U.S. EPA direction, which resulted in increased estimated fugitive emissions. As direct measurement and detection technologies evolve, emission factors are expected to be improved or replaced with better approaches industry-wide. 

Advocacy and collaboration

The energy industry is collaborative by nature. We work with industry partners and regulators around the world to advocate for strong and consistent measurement, reporting, and verification standards. We also collaborate with universities, industry groups, and others to advance the technologies and fundamental science related to methane emissions.

Supporting rational and constructive policy

The model regulatory framework we published in 2020 provides a blueprint for industry-wide regulation, urging stakeholders, policy makers, and governments to develop comprehensive rules for methane emissions.

We work with the European Commission Directorate-General for Environment, the U.S. Environmental Protection Agency, the U.S. Bureau of Land Management, state regulators, and others to encourage practical and effective regulation of methane emissions. In the United States alone, half a dozen agencies work on methane rules. If not well coordinated, this could lead to overlapping and potentially conflicting regulations. This is why we’re focused on rational and constructive policy that supports the deployment of technology and builds on successful industry efforts.

The commentary and guidance we’ve offered regulators includes:
