“Sniffing” for methane emissions in the US
The US industry faces a methane challenge. For Equinor, sitting back was never an option. Applying innovative technologies in our US onshore operations – including drones and infrared cameras – reduced our emissions by 80% from 2014 to 2018. Here, we explain how.
On November 21st we submitted comments to the US Environmental Protection Agency (EPA) outlining our view that regulation of methane is necessary. For more details, see below.

The shale revolution in the US started just over a decade ago. Between 2005 and 2018, US natural gas production rose 70%, surpassing Russia during this time to lead global output.
More production means more methane, the primary component of natural gas. As production ramped up, questions were raised about how much methane was being leaked throughout the gas value chain.
Minimizing methane emissions is essential to the future of our industry. Combustion of natural gas releases significantly less CO2 than coal, but this advantage is reduced by methane leaks during production and distribution. While methane has a shorter lifespan in the atmosphere than CO2, it has a higher warming potential – about 34 times higher over a 100-year period, according to the Intergovernmental Panel on Climate Change.
The methane intensity of Equinor’s natural gas production is low – around 1/10 of the industry average – but we are committed to continuously improving our performance. Alongside industry partners, we are working towards near-zero methane emissions across the gas value chain.
On November 21st, 2019, we submitted comments to the US Environmental Protection Agency (EPA) outlining our view that regulation of methane is a necessary part of a comprehensive, economy-wide policy program to address global climate change:
- Reducing emissions is an important part of Equinor’s approach to providing low carbon energy
- We lowered our US onshore emissions by 80% between 2014 and 2018
- We support the direct regulation of methane at the federal level.
“Reducing emissions is an important part of Equinor’s approach to provide low carbon energy. We support the direct regulation of methane in the US at the federal level.”

Maintaining a leading voice on policy
The industry’s voluntary efforts have already done much to reduce methane emissions. However, there is more that can and should be done. We support the direct regulation of methane in the US at the federal level. A federal regulatory “floor” can provide industry a consistent, flexible, predictable, and comprehensive policy framework to drive collective improvement.
“Credible, courageous, and collaborative action is needed to maintain our license to operate. Equinor supports effective federal EPA regulations on methane and aims to work with authorities to continuously improve and develop regulations,” says Bjørn Otto Sverdrup, senior vice president for sustainability.
In August, the US Environmental Protection Agency (EPA) released a proposal to roll back methane emission performance standards established in 2016. Equinor quickly voiced support for continued regulation following this announcement. We have submitted comments to the US Environmental Protection Agency (EPA) outlining our view that direct regulation of methane is a necessary part of a comprehensive, economy-wide policy program to address global climate change.
What is methane, and why is it important?
- Methane is the second most important greenhouse gas contributing to human-induced climate change.
- Methane has a shorter lifespan in the atmosphere than CO2, but it has a higher warming potential.
- While natural gas releases significantly less CO2 than coal when combusted, methane emissions during production and distribution reduce this advantage.
- Minimizing methane emissions is therefore essential.
“Equinor now has extensive protocols across our onshore operations to detect and mitigate fugitive emissions.”

Equinor’s methane emissions
- In 2018, Equinor’s total US onshore methane intensity was 0.046 kgCH4/boe, or 0.07% of production.
- The methane leakage rate (fugitive methane) for Equinor’s US facilities is 0.03% of production.
Collaborating & innovating toward a low carbon future
Collaboration is instrumental to improved understanding and performance. Equinor is a member of multiple industry and academic initiatives focused on finding better ways to detect and prevent methane emissions.
One such initiative, the Mobile Monitoring Challenge, co-sponsored by the Environmental Defense Fund and Stanford University, explored technologies for mobile methane lead detection. The results, released in September 2019, showed promise in drone-mounted laser sensors developed by SeekOps Inc. that can detect, locate, and quantify methane leaks. Equinor was the first industry adopter and investor in SeekOps’ technology, deploying drones at our US onshore facilities since 2016.
The investment fund of the Oil & Gas Climate Initiative (OGCI), a group of leading companies representing 30% of global oil and gas production, has now joined Equinor as a strategic investor in SeekOps, signaling growing industry interest in remote sensing technology. Equinor is a founding member of OGCI.
Equinor also participates in several industry groups, such as the American Petroleum Institute’s Environmental Partnership, focused on sharing best practices and promoting voluntary standards above current regulations. This is an issue that Equinor cannot solve alone and we will continue to work with industry partners to learn, share experience and improve on the status quo.
