Pinnacle Midstream II - GHG emissions profile

Emissions Insight: Pinnacle Midstream II

Pinnacle Midstream II reported 7K metric tons of CO2-equivalent in 2023, placing it at rank #2233 among all EPA Greenhouse Gas Reporting Program (GHGRP) reporters and #147 within the Petroleum and Natural Gas Systems category. The company operates 1 reporting facility distributed across 1 state, giving an average of approximately 7K metric tons of CO2e per facility. Only sites emitting 25,000+ metric tons of CO2e annually are required to report, so these figures represent the company's largest operational emitters rather than its entire carbon footprint.

Classified in the Petroleum and Natural Gas Systems sector (NAICS code 211130), Pinnacle Midstream II sits alongside peers subject to the same reporting thresholds under 40 CFR Part 98. Across the 1 reporting year on record, the data shows a single snapshot without multi-year trend context. This multi-year lens is critical because year-on-year variation may reflect production volume, fuel mix, facility acquisitions or divestitures, and efficiency upgrades rather than underlying operational intensity.

For analysts and policy users, the key takeaway is that this profile reflects self-reported Scope 1 combustion, process, and fugitive emissions verified by the EPA, not Scope 2 purchased electricity or Scope 3 value-chain emissions. When comparing Pinnacle Midstream II to other large emitters, weight the 1-facility footprint against the 7K MT total to understand concentration risk. California SB 253 and SEC climate disclosure rules will push many GHGRP reporters toward broader Scope 1–3 reporting over the next reporting cycles, so this EPA baseline will remain the comparable backbone for tracking corporate carbon performance.
