- Insufficient data to meaningfully quantify Scope 3 GHG emissions
- Limited or no public disclosure of GHG emissions from many crude oil suppliers and customers
- Difficulty in accurately assessing upstream and downstream carbon emissions
- Inconsistencies in emissions calculations that disadvantage U.S. domestic crop-based biofuels due to ILUC penalties
Valero Energy Corporation
Greenhouse gas emissions & sustainability report data
In its 2023 reporting, Valero Energy Corporation disclosed greenhouse gas emissions of 24.9 million metric tons CO2e. By scope: Scope 1: 24.9 million metric tons CO2e (refining); Scope 2: 10 million metric tons CO2e (refining). Figures are as stated in the company's own report and may use different boundaries, units or methods (for example market-based vs location-based Scope 2), so compare with care.

🎯 Climate & Sustainability Targets
🔜 Short-term
- Reduce and displace the equivalent to 63% of the tonnage from global refinery GHG emissions (Scopes 1 and 2) by 2025 (achieved)
📅 Medium-term
- Reduce and displace the equivalent to 100% of the tonnage from global refinery GHG emissions (Scopes 1 and 2) by 2035
🔭 Long-term
- Reduce and displace company-wide GHG emissions for Scopes 1, 2, 3, and 4 by more than 45 million metric tons CO2e by 2050
