Using coal? But what for? – Jean-Marc Jancovici
steel manufacturing (about 7% of the world coal), which is then used to build trains, rails, and concrete irons that are themselves used to build stations and tunnels, cement manufacturing (4% of the world coal), also used to build stations and tunnels. And as trains are environment-friendly, coal is also ! Or did I miss something ?
Coal & steel - World Coal Association
Steel is produced via two main routes: the blast furnace-basic oxygen furnace (BF-BOF) route and electric arc furnace (EAF) route. The BF-BOF route is used for 71% of steel produced, whilst the EAF route accounts for 29% of steel produced. The key difference between these routes is the material used to produce the steel and the plant configuration.

Laying the foundation for zero-carbon cement - McKinsey & Company
Adding CO 2 makes the concrete stronger and reduces the amount of cement needed. Carbon-cured concrete could also use CO 2 captured during cement production. Today's methods could sequester up to 5 percent of the CO 2 produced during production, but newer technologies could sequester 25 to 30 percent.
