Greenhouse Gas Emissions
GREENHOUSE GAS EMISSIONS
Together, with Nippon Steel Corporation (NSC), U. S. Steel continues to pursue the leading edge of energy efficiency in blast-furnace steelmaking to minimize those emissions as well as increasingly enlisting electric arc furnaces (EAFs) to make steel by melting recycled steel scrap, significantly reducing GHG emissions and creating opportunities for renewable energy use. Both steelmaking technologies are important to our operations during the transition to a lower-carbon economy.
We hit an important milestone in 2025 in our progress toward lowering Scope 1 and Scope 2 emissions. Compared to our 2018 baseline, we have reduced our emissions intensity by more than 22%, meeting our 2030 goal early.
Due to this achievement, we are working with NSC to develop a new interim or medium-term target for greenhouse gas emissions.
| GHG Emissions (CO2e)1 | 2025 |
|---|---|
| Scope 1 – Total Corporation* | 23.20 |
| Market-Based Scope 2 – Total Corporation* | 3.15 |
| Scope 1 GHG Intensity² – Total Corporation* | 1.52 |
| Market-Based Scope 2 GHG Intensity² – Total Corporation* | 0.21 |
Reporting timeframe is January 1, 2025, to December 31, 2025
*Total Corporation includes U. S. Steel and U. S. Steel Košice.
1. GHG emissions are reported in million metric tonnes of total carbon, methane, and nitrous oxide converted to carbon dioxide equivalents and excludes GHG emissions from on-site landfills. The annual amounts vary based on a variety of factors including operating facilities, production levels, and energy efficiency projects implementation.
2. The GHG emissions intensity is based on the total quantity in metric tonnes of GHG emissions calculated in accordance with GHG Protocol standards divided by the total quantity in metric tonnes of raw steel produced that is processed into finished steel products.
