Yes - I think in 20 years - we will need far less steel and cement as we have better alternatives, and there will be alternatives to fossil fuels by then for producing steel and cement anyway. In the short term - CC is not a solution - there's too much carbon being emitted and there isn't an economical, scalable solution anyway. We are going to emit what we're going to emit - and no amount of realistic CC is ever going to dent what we've already done by the time the technology is ready.
