Along with aviation, the construction industry is one of the hardest to decarbonize sectors in the global economy. Cement and steel production together are responsible for about 15% of global CO2 emissions. But look around our modern world and it’s hard to imagine doing without these materials.

Carbon-negative cement has been talked about for years, and innovations in steel production show promise as well, but is either technology ready for primetime? And what about replacing these materials with engineered wood, which could also store carbon for decades?
