Steel
Country and regional highlights
Near zero-emission projects advance fastest in Europe, with some progress for low-emissions facilities globally
CO2 emissions
The CO2 emission intensity of steel has been relatively stable in recent years, but needs to drop significantly to align with the NZE Scenario
Energy
A reduction in reliance on coal and an increase in electricity use are required to get on track with the NZE Scenario
Activity
Material efficiency strategies are required to balance demand growth
