Global iron and steel plant CO2 emissions and carbon-neutrality pathways
The iron and steel industry, a major source of CO2 emissions, is crucial for addressing climate change. A study mapped emissions and technologies for over 4,800 individual plants, creating tailored plans to reduce emissions. Retrofitting these plants with low-carbon tech during their operational years can limit global warming to 2°C, while advanced retrofitting can aim for 1.5°C. If plants retrofit 5 years earlier, it could cut global emissions by double the 2021 total. This research outlines a path for the iron and steel sector to achieve net-zero emissions.
