What is the carbon footprint to produce a ton of steel?

The carbon footprint to produce a ton of steel typically ranges from 1.5 to 2.0 tons of CO2 emissions, depending on the production method used. Traditional blast furnace processes, which rely heavily on coal, tend to have higher emissions compared to more modern methods like electric arc furnaces that can utilize recycled scrap steel. Efforts to reduce this footprint include adopting cleaner technologies and increasing the use of renewable energy sources in steel production. Overall, the steel industry is a significant contributor to global greenhouse gas emissions, prompting ongoing research and innovation for more sustainable practices.
