>cement, steel Beats me. I think we'll just have to just stop using so much of it. There is likely a decent amount of buildings being completely unused that could be turned into housing. Turn most office jobs into remote jobs. Turn most office buildings into apartments. >shipping, and aviation These options absolutely exist. For aviation, we could simply stop traveling so much and establish a network of electric cars to move people (coordinating tens of drivers in Uber/Lyft fashion with electric vans to move a family across CONUS is easily doable with our current technology). Nuclear cruise ships could replace trans-continental flights but you'll likely want to keep those flights for a while so the public gets used to the idea of "nuclear" and "cruise ships" in their vacations. Replacing shipping means nuclear, which means yeeting a bunch of 2nd/3rd world nations' current ships and incomes. All of this of course requires a much more authoritarian stance than current world politics tolerates (and guaranteeing that the leader doesn't start purging people). Unfortunately, climate change isn't as dramatic as a meteor headed toward Earth. It's very difficult to sell the complete destruction of major industries and companies to anyone, even though dealing with an economic armageddon is obviously easier to deal with than a planetary climate armageddon.
