Renewable power capacity in net zero pathways for heavy industry is projected to climb to 201 gigawatts by 2030, yet carbon cuts still hinge on what happens inside cement kilns and steel furnaces. Cement accounts for 66% of its emissions from calcination, while 53% of steel GHG output is tied to blast furnace and basic oxygen routes. The same gap appears in reporting and readiness, with only 38% of EU cement companies covering a whole value chain climate target.
