Earlier quoted context omitted.
Steel production is one of the largest contributors to global C02 emissions. Reducing it by 30% isn't a solution. Unfortunately, zero-carbon-emissions steel is still not feasibile, which is a major, major issue for the health of our planet.
We have to start somewhere don’t we?
Yes -- but it's not a start unless we're making zero-emissions steel possible. Otherwise, it's just more of the same. (Akin to stabbing someone with a 30% smaller knife.)
