The article makes only a glossed-over mention of fiberglass rebar, which is about 1/7th the weight of steel, faster to install, creates no EM issues, does not rust and costs less. Here's some examples, admittedly from those selling it [1][2], and from other news/ industry sources [3]. also, other fibers such as basalt provide even better properties [4].

All it takes is for architects and engineers to get their heads around new technologies and start specifying better materials. This wouldn't fully solve the CO2 problem of concrete, but it would reduce it by making each ton of concrete last a lot longer.
