Since Nucor entered the steel business more than 50 years ago, sustainability has been a foundation of its operations. Nucor is a leading pioneer in the use of electric arc furnace (EAF) technology, a circular process that recycles scrap metal into new steel products.
As a result, Nucor is among the cleanest steel producers in the world with an emissions intensity that is less than one-third the global average of extractive steelmaking methods using blast furnaces for Scope 1, 2 and 3 emissions, and 20 years ahead of the Paris Agreement’s 1.5°C scenario.
Still, Nucor is striving to reduce the environmental impact of our steelmaking even further, in line with our commitment to a 35% reduction in greenhouse gas (GHG) intensity by 2030 (from a 2015 base year).
While Nucor steel averages 75% recycled content, other inputs into our steelmaking including iron (e.g., direct reduced iron and pig iron) account for a significant share of our own indirect emissions.
