As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

That would be red, unless you have something else in it. But it is actually about turning iron ore, which is basically dirty iron oxide, into pure iron:
Fe~2~0~3~ + 3H~2~ → 2Fe + 3 H~2~O
It's this BS where everything done with renewables is green
So if you burn green hydrogen to make iron, the iron is green
Hmmm I heard of studies/prototyping/research to completely overhaul steel production in order to reduce the (gigantic) carbon footprint. It might be linked?
Not just heating it differently, really change the process.. Searching for source, will update.
Edit: not exactly what I was looking for but I found this: https://www.canarymedia.com/articles/clean-industry/us-pledges-up-to-1b-for-two-pioneering-green-steel-projects
Using hydrogen instead of coal, not for heating but for the reaction actually creating iron. I remeber reading about rotating furnace, like the one used to create cement.
