CNX ESG Performance Scorecard

Review of Scorecard Data

CNX obtained limited assurance from Keramida, Inc., a WBE certified global sustainability and EHS services firm, for certain quarterly ESG data presented on this ESG Performance Scorecard, including Scope 1 and Scope 2 greenhouse gas emissions, air emissions, water, and waste data. CNX’s Internal Audit & Advisory Services team performed limited procedures over all other quarterly data presented in the scorecard as part of its advisory role in assessing ESG-related processes and disclosures. The procedures performed were limited in scope and did not constitute an audit or assurance engagement; thus, no assurance is expressed or implied. Note that certain financial data included in the scorecard is also subject to internal control procedures that are required for the Sarbanes-Oxley Act Section 302 certifications included in our SEC filings.

  1. Employee count based on active employment status as of end of reporting period. Contractor Full-Time Equivalent (FTE) based on 2,080 workhours per year.
  2. NGLs, oil and condensate are converted to Mcfe at the rate of one barrel equals six Mcf based upon the approximate relative energy content of oil and natural gas.
  3. Total recordable incident rate (TRIR), lost time incident rate (LTIR), and days away, restricted or transfer (DART) rate, are calculated per 200,000 hours worked. The reportable motor vehicle incident rate is calculated per 1,000,000 miles driven.
  4. Motor vehicle incident is any incident involving a licensed motor vehicle, which results in an OSHA recordable injury.
  5. Includes total emissions from CNX Production and Gathering and Boosting segments based on EPA’s Subpart W methodology, consolidated and reported under the operational control approach.
  6. Greenhouse global warming potential for CO2e calculations are based on IPCC Fifth Assessment (AR5-100 year) for 2024 and forward. GHG and Methane intensities are calculated using applicable emissions divided by throughput for Production and Gathering and Boosting segments, respectively.
  7. All emissions metrics, including intensity calculations follow the applicable EPA Greenhouse Gas Reporting Program methodologies under Subpart W – Petroleum and Natural Gas Systems, then in effect for each respective reporting year 2025 reflects Subpart W revisions mandated by Section 136(h) of the Inflation Reduction Act.
  8. Scope 3 emissions are indirect emissions from the use of our sold product and are calculated utilizing natural gas combustion emission factors from Subpart C of EPA’s Greenhouse Gas Reporting Program. In order to provide more transparency and with the goal of aiding more standard and consistent GHG emission disclosures that enable true full lifecycle emissions profile comparisons across industries, CNX is committed to providing additional disclosures on downstream as well as upstream Scope 3 emissions in future performance scorecards.
  9. Flaring intensity based on total volume of natural gas produced.
  10. Leak detection and repair (LDAR) surveys that meet minimum federal and state regulations.
  11. Amounts include water that has been brought into the CNX system and consumed by gas operations; excludes amounts based on engineering estimates that were transported across but not consumed within the system. Prior year amounts have been adjusted to reflect this methodology.
  12. Water consumed in operations primarily relates to hydraulic fracturing, adjusted for minor changes to storage.
  13. Includes produced water and flowback fluids sent to injection wells and other disposal facilities.
  14. Fresh water withdrawn intensity equals fresh water withdrawn divided by total company gross operated production (Mboe).
  15. Total water consumed intensity equals water consumed in operations divided by total company gross operated production (Mboe).
  16. Water recycled/reused rate equals the sum of produced water consumed in operations plus produced water sent to third-parties for reuse divided by total produced water brought into the CNX system.
  17. Water disposed offsite rate equals the amount sent to offsite disposal divided by total water brought into the CNX system.
  18. Includes violations issued by state and federal safety and environmental regulatory agencies, based on date violation was received.
  19. NOVs and Penalty Payments received during the reporting period are excluded if the violation stemmed from conditions that existed prior to the acquisition of Apex, as the company did not have operational control at the time of the incident.
  20. Reportable pipeline incidents are those that are reportable under US DOT PHMSA’s pipeline safety regulations.
  21. Spills include releases off containment to the environment greater than or equal to 42 gallons.
  22. Spills discovered during the reporting period are excluded if the incident resulted from conditions that existed prior to the acquisition of Apex, as the company did not have operational control at the time of the spill.
  23. Spill intensity is calculated as total barrels of liquid released (hydrocarbon and non-hydrocarbon) divided by total barrels of produced liquids (CNX and third‐party produced water and CNX condensate), with results expressed per 100,000 barrels.

General Notes:

  1. These metrics have been calculated using the best available data at the time of publication. Historic metrics are subject to change as we continuously seek to improve data management processes and methodologies as CNX strives to provide a high level of transparency, consistency, and accuracy.
  2. Data shown as “-” represent the value of zero. Data shown as “0” represent a value less than one, rounded to zero.
  3. In some instances, amounts reported on the quarterly CNX ESG Performance Scorecard may not foot to the reported annual amounts, and subtotals may not foot to totals, due to rounding.
