You may be surprised to learn that cement production alone makes up 8% of global carbon emissions. Steel production is 5% by itself.

- hannob 6y agoNo, not surprised, well aware of that. We should really get started developing alternatives. Cement is a tough one, probably the toughest industry sector at all. For steel the swedish companies SSAB+LKAB have a very ambitious plan using hydrogen. I hope they succeed doing that. That said and as othes have noted: Aviation is 2% of CO2, but a much larger share of overall emissions. I was surprised to recently learn that this is scientifically underresearched (particularly effects on cloud formation) and it may be everything between 4 and 7%.
