Climate advocacy groups are urging the European Union to establish a mandatory definition for low-emission steel within the Industrial Accelerator Act. SteelZero welcomes the EU's direction but warns the legislation currently lacks the clear, science-based standard needed to make public procurement effective. The term "low-carbon steel" now carries two meanings, referring both to a traditional metallurgical grade and to production emissions. ResponsibleSteel's CEO cautions that while the Act's principles are sound, their application requires strengthening to provide investment certainty and drive genuine industrial decarbonisation.
