The iron and steel industry is one of the largest industrial sources of CO2. Globally, it accounts for about 6% of anthropogenic CO2 emissions from energy use. One of the leading options being considered by the steel industry stakeholders to reduce CO2 emissions from steel mills (specifically from integrated steel mills) is carbon capture and storage (CCS). Development of this technology for application in iron and steel production is still ongoing. This is the first workshop initiated and organised by the IEA Greenhouse Gas R&D Programme with an aim of gathering key industry stakeholders and providing a forum for discussion.
