Total CO 2 emissions from the iron and steel sector have risen over the past decade, largely owing to increases in steel demand. Substantial cuts in CO 2 emissions are essential to get on track with the NZE Scenario, under which emissions intensity falls by about a quarter by 2030. Short-term CO 2 emission reductions can be achieved mostly ...

As such, there is a compelling need to explore low-carbon transition pathways for China's iron and steel industry, which require transitions from both the consumption and production sides [13]. On the consumption side, material efficiency (e.g., increasing product lifespans to reduce replacement demand) plays a vital role [11], [14].

Iron and steel consist of grains made of different kinds of iron and carbon, some of which are hard, while others are soft. When the harder kinds predominate, you get a hard and brittle material; when there are more softer kinds in between, the material can bend and flex so you can work and shape it more easily.
