Emissions Insight: Valero Energy

Valero Energy reported 23.5M metric tons of CO2-equivalent in 2023, placing it at rank #17 among all EPA Greenhouse Gas Reporting Program (GHGRP) reporters and #1 within the Petroleum Product Suppliers category. The company operates 26 reporting facilities distributed across 11 states, giving an average of approximately 904K 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 Product Suppliers sector (NAICS code 324110), Valero Energy sits alongside peers subject to the same reporting thresholds under 40 CFR Part 98. Across the 13 reporting years on record (2011–2023), the data shows a rise of 0.1% in annual emissions. 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 Valero Energy to other large emitters, weight the 26-facility footprint against the 23.5M 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.
