Optimistically, we’re already seeing European corporations growing initiatives on lower-emission concrete and inexperienced metal manufacturing.

Amongst them, is the Finnish Betolar, a enterprise is creating a substitute for cement-based concrete. There are additionally Swedish producers H2 Green Steel and SSAB, that are growing hydrogen-based inexperienced metal options.
