Independent Limited Assurance
Since 2021, we have engaged one or more independent third parties to evaluate, validate and/or verify our GHG
emissions disclosures, which we intend to continue completing annually going forward. In 2025, this included
limited assurance on/of:
• Company-wide 2024 Scopes 1 and 2 GHG emissions, including re昀椀ning, renewable diesel and ethanol
segments.
• Company-wide 2024 life cycle GHG emissions displacements from our renewable diesel, SAF and ethanol
production, as well as the blending of and credits from low-carbon fuels.
• Company-wide 2024 GHG emissions from the use of our products on an intensity basis (Use of Product GHG
Emissions Intensity).
• Global re昀椀nery 2024 Scope 1 intensity per barrel.
• The validation of our 2035 GHG emissions reduction/displacement target.
Copies of independent limited assurance veri昀椀cations can be found on our website at
www.valero.com > Investors > ESG > Other Reports. All calculations were found to be science-based and in
conformity with acceptable engineering practices.
Our Progress up to 2024
Scope 1 Intensity — GHG emissions from the refining process relative to refining peers
The following chart compares Valero’s global re昀椀nery Scope 1 intensity in million metric tons CO2e per thousand
barrels of oil equivalent (BOE), relative to peers’ performance using peers’ publicly available disclosures,
including annual reports on Forms 10-K and sustainability reports.
