Natural gas is the catalyst for a more sustainable future. No fuel has contributed more to the United States’ leadership in emission reductions than natural gas. Replacing higher emitting fuels and imported LNG with resources produced safely in the Appalachian Basin, is the best option for meeting growing energy demand while furthering environmental progress. The Appalachian Basin is the lowest methane emission intensity basin in the United States, and CNX is a leader in the basin in driving meaningful methane emission reductions.

CNX operates exclusively within the Appalachian Basin.

Methane Emissions Intensity is calculated as methane emissions divided by natural gas sold. Emissions calculated using 2022 EPA Subpart W methodology for Onshore Production segment.

CNX’s Emission Reduction Task Force (ERTF) consists of members from various operational, environmental, engineering, and data management teams and focuses on reduction of CNX’s methane emissions. The ERTF meets regularly to prioritize opportunities with the greatest potential to reduce CNX’s overall emission footprint.

From 2020, through the end of 2023, CNX produced 2.5 quadrillion BTUs of life-sustaining energy—enough equivalent energy to power nearly 8 million homes per year1—while reducing operational methane intensity by 52% in our production segment, and by 31% in our gathering and boosting segment. These improvements were achieved primarily by controlling vented emissions from our pneumatic devices and by managing the emissions related to water handling during well completions and well liquid unloading events, which led to significant reductions.

In 2023, we allocated $7 million of capital investment to methane emission mitigation efforts. This capital was used to make changes to our pneumatic devices and our liquids unloading procedures, resulting in an annualized methane benefit of over 85,000 tons CO2e.

In 2024, we plan to continue our methane emission mitigation efforts by spending $5 million on similar projects, in addition to mitigation efforts related to our dehydration units, with expected annualized benefits of over 85,000 tons CO2e. The resulting projected methane intensities will reinforce CNX’s position as a leader in the lowest emission basin in the United States.

In 2024, we expect to achieve annualized benefits of over 85,000 tons CO2e, resulting in methane intensities of approximately 0.02% or lower in both Production and Gathering and Boosting segments. By the end of 2025, we maintain a targeted 200,000 tons CO2e reduction compared to our 2020 baseline.

Since 2021, executive compensation has been tied to annual methane intensity reduction targets through our long-term incentive program, explicitly linking pay to ESG performance. For the third straight year, CNX outperformed against these targets and—due to the strength of our team and their commitment to innovation and continuous improvement—we are confident that we can achieve our future milestone reduction goals by focusing on efficiency and utilizing new technology.

For the last four years, CNX has drastically reduced our methane intensity. This trend will continue in 2024, where our goals are to reduce both production and gathering and boosting segment methane intensities to approximately 0.02% or lower, resulting in reductions of approximately 71% and 43% respectively, since 2020.

Methane Emissions Intensity is calculated as methane emissions divided by natural gas produced or transported. Emissions calculated using 2022 EPA Subpart W methodology for Onshore Production and Gathering & Boosting industry segments.

Because of its high radiative efficiency compared to carbon dioxide, mitigating methane emissions and methane intensity in the oil and natural gas industry has been recognized as one of the best opportunities for reducing near-term global warming. The Inflation Reduction Act, passed by Congress in 2022, incentivizes methane emission reductions by creating a methane fee, which applies to oil and gas operators with methane intensity levels in excess of specified thresholds. CNX will be nearly 90% and 75% below the methane fee thresholds for the two industry segments that we operate within, thanks to our past and ongoing methane emission reduction efforts.

In addition to our operating methane emission reductions, CNX actively reduces methane emissions from other industries through our waste methane abatement initiatives. We capture approximately 9.1 million tons CO2e of waste methane annually, which is significantly more methane than we emit from our operating activities CMM section. This residual waste methane would otherwise be vented to the atmosphere during the mining process. Methane emissions from coal mining activities represent nearly 10% of all U.S. methane emissions. Rather than releasing it to the atmosphere, CNX captures, processes, compresses, and transports waste methane to market for beneficial use—one of only a handful such projects in the nation.

CNX goes beyond regulatory requirements to drive improvements in our operating workflows, practices, and procedures in our production and midstream operations. Our leak detection and repair (LDAR) process utilizes proprietary software, developed in-house, to provide automated repair work order notifications and leak detection tracking. This process allows for timely repair of leaks well within regulatory requirements. We also aim for earlier and more effective detection of fugitive emissions and more expeditious mitigation of leaks at the source. CNX utilizes multiple early detection devices, including drone technology and OGI camera surveys, and continuous monitoring ground detection systems. A more complete description of our methane detection program can be found on our Radical Transparency program website.

CNX is a member of the Appalachian Methane Initiative (AMI), a coalition of leading U.S. natural gas companies, independent methane monitoring survey providers, technical consultants, and top-tier universities engaged in scientific analysis. The coalition aims to further enhance methane emissions monitoring and reductions throughout the Appalachian Basin through a cooperative approach and sharing of best practices. AMI’s 2024 campaign is expected to monitor more than 20,000 square miles of the Appalachian Basin, including gas production facilities representing 31.5 bcf/d of production capacity (roughly 90% of the daily production within the basin), approximately 6,000 oil and gas sites, and approximately 180 non-oil and gas sites, such as coal mines/vents and landfills.

1 South Station

The 1 South IP Station is the first intermediate pressure (IP) compressor station in CNX’s Virginia operations designed not only to be emissions free, but with a continuous emissions monitoring system. The Virginia team collaborated with Teledyne FLIR, installing three FLIR GF77a cameras in strategic areas for full coverage of the station. The cameras monitor for leaks of methane gas 24/7 and stream live video to the Virginia operation’s gas control room where operators can remotely shut down individual compressor units or the entire station if required. Pending continued favorable results, CNX plans to deploy FLIR cameras to other facilities.

CNX’s Regulatory Reporting Group is responsible for enhancing our regulatory and environmental compliance data management processes. Given the importance of environmental data integrity and transparency and validation of emissions data, this team is devoted to non-financial regulatory data gathering, validation, and reporting. This has improved the timeliness, reliability, and accuracy of our reports, providing emissions data to stakeholders and improving our environmental performance as we utilize the data in our operations. CNX shares best practices with peer companies to help lead the domestic energy industry in this important arena.

In addition to reporting direct Scope 1 emissions, CNX reports both Scope 2 and Scope 3 emissions, which are indirect emissions related to the generation of the electricity that we purchase and the estimated downstream use of our natural gas production. All three categories are reported in the ESG Performance Scorecard.

Commitment to GHG Emissions Reduction

CNX’s GHG emission reduction efforts include:

Adopting green completions across all of our operations, in which gas produced during flowback operations is captured, rather than being vented to the atmosphere. Improvements include use of CNX patented technological development. See Process Innovation

Improving our environmental management information system by leveraging existing supervisory-control and data acquisition systems to further automate data collection.

Installing emissions controls on tanks and storage vessels located at unconventional well pads.

Reducing fugitive methane emissions from pipeline pigging activities via predictive maintenance, redesigned work procedures, and state-of-the-art methane capture technology.

Increasing frequency of routine monitoring for leaks at all well sites and compressor stations.

Conversion to an electric frac fleet and electrified drilling rig.

Electric Frac Fleet

CNX was a first mover in the Appalachian Basin on all-electric frac spreads, phasing out the use of diesel frac fleets in early 2019. We are now at 100% electric frac fleet usage in our shale completion operations. This not only reduces CO2 emissions from our operation, but has the added benefit of helping CNX achieve its safety, cost savings, and operational efficiency targets, and reduces noise pollution.

Responsibly Sourced Gas (RSG)

Producers and buyers of RSG, a differentiated gas commodity, want to understand the environmental footprint of the molecules they sell or purchase. This requires docu-mentation, tracking, and book-and-claim capabilities. CNX is engaged with Project Canary, which audits and verifies the environmental attributes of RSG and publishes its results to a public registry, increasing transparency for concerned stakeholders. CNX conducts monitoring at our production facilities on a significant portion of the gas we sell to market and has received Project Canary’s highest rating (Platinum) for some sites, a process which requires an environmental assessment, continuous monitoring technology, and quantification of methane emissions intensity. CNX is also engaged with a blockchain-based emissions accounting provider that trans-forms verified environmental attributes into digital tokens, making the buying and selling of these assets significantly easier and more trustworthy.

Integrated Midstream

CNX’s integrated midstream approach offers several advantages over the conventional relationship between a gas producer and a third-party midstream company. Typically, a gas producer pays for a given takeaway capacity, and delivers all wellpad volumes into a pipeline system within a contractually determined range of pressures. This allows the midstream company to determine how much compression power is needed to fulfill its obligation to the producer. The pressure at the point of custody transfer is typically relatively low, so a significant amount of compression is required to compress volumes from newer wells. This inefficiency cannot be significantly mitigated, as it is enforced by the gathering contract.

In contrast, CNX tailors its gathering system designs to allow the newer wells to bypass compression (“freeflow”) if they have sufficiently high wellhead pressure and adjust its production schedule to avoid brief “peaks” of required compression power at any given location, minimizing the amount of compression within any gas field—whether measured in number of units or in total compressor power. For 2023, CNX estimates that about 6.5 additional compressor units (driven by CAT 3608 engines) or about 12,500 hp would be needed to gather CNX’s freeflow volumes at a conventional 350 psig. CNX’s integrated approach avoids the capital and operating expense of these units, as well as the lost revenue and GHG emissions associated with their fuel burn, approximately 57,000 tons annually of CO2e.

Alternative Energy Certificates

Coal mine methane (CMM) is typically released into the atmosphere. Policy makers have recognized the environmental value of CMM emissions mitigation by including it as a qualifying Tier 1 Resource in Pennsylvania Alternative Energy Portfolio Standard (AEPS) program. Using captured CMM for power generation and delivering the power into the PJM market creates Pennsylvania Public Utility Commission Tier 1 alternative energy certificates (AECs). Throughout 2023, CNX captured approximately 15-18 Bcfe (8,000,000-9,500,000 MT CO2e) of CMM, which was primarily directed towards the AEPS program.

Electrification of the Drilling Rig

Following the successful transition to an electric frac fleet, CNX is in the final stages of electrifying our drilling operation. Natural gas generators, fueled by our field gas and coupled with an electric air package, will help eliminate diesel fuel from the drilling rig, reducing emissions and noise level in this phase of operations. This package can be applied to both top hole and horizontal rigs, and allows ancillary equipment to be added to the power distribution.
