SUSTAINABILITY OUR GREENHOUSE GAS REDUCTION TARGET STRATEGY Nucor already has a carbon intensity less than one-third of today’s world average. Which puts Nucor 18 years ahead of the below 2-degrees target. But we know that is not enough, and we are committed to going further. Nucor is committing to a 35% combined reduction in steel mill scope 1 and scope 2 GHG intensity by 2030 using 2015 baseline goals. This goal will take Nucor’s steel mill CO2 emissions down to 77% less than today’s global steelmaking average. In addition: In addition to scope 1 and 2, Nucor will continue to publicly disclose and reduce scope 3 emissions. Nucor has already achieved and will continue to meet the Paris Agreement and below Two Degree Scenario based on the GHG sector-based benchmarks established in 2021 by the Transition Pathways Initiative (TPI). Beyond 2030, we are committed to continuing reductions in steel mill carbon intensity towards net zero-emission steel at scale. Nucor teammates have developed a data driven, multi-pronged approach to ensure our success.
