CNX ESG Performance Scorecard

Review of Scorecard Data

CNX’s Internal Audit & Advisory Services team performed limited procedures over the 2025 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 year-end. Contractor 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), days away, restricted or transfer (DART) rate, and safety and environmental investigations rate are based off 200,000 hours worked annually. Reportable motor vehicle incident rate is based off 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 based on IPCC Fourth Assessment (AR4-100 year). GHG and Methane intensities 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.
  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. Produced water injection, disposal, and recycled and reused rates are all based on total volume of produced water generated by the company.
  12. Includes third party produced water.
  13. Total water consumed equals total fresh water withdrawn plus total produced water (less water sent to disposal and/or third-parties).
  14. Water recycling rate equals produced water recycled and reused divided by total water consumed.
  15. Fresh water consumed intensity equals total fresh water withdrawn divided by total company gross operated production (Mboe).
  16. Total water consumed intensity equals total water consumed divided by total company gross operated production (Mboe).
  17. Includes violations issued by state and federal safety and environmental regulatory agencies, based on date violation was received.
  18. NOVs 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.
  19. Reportable pipeline incidents are those that are reportable under US DOT PHMSA’s pipeline safety regulations.
  20. Spills include releases off containment to the environment greater than or equal to 42 gallons.
  21. 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.
  22. Spill intensity equals barrels of liquid (hydrocarbon and non-hydrocarbon) releases divided by 100,000 barrels of total produced liquids (hydrocarbon and non-hydrocarbon).

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.
