“There are currently no feasible renewable alternatives for making steel,” she said.

That’s pretty much it, once we have green steel off the ground there will be no excuse for this, in the mean time not much we can do

I mean, what’s the alternative here? I’m all about renewables for power generation but we can’t solar, wind or hydro our way to steel. We either stop building stuff, or we continue to use coal for that.

The four mines will target mostly coal to be used for steelmaking with some thermal coal for burning in power stations.

I’m very interested in the specifics of how the word “some” is employed here.
10%? Ok.
90%? Not ok.
