Queens Carbon’s mission is to Decarbonize the Cement and Concrete Industry. Backed by Breakthrough Energy Fellows and ARPA-e, we’re developing a novel synthesis process that dramatically reduces the CO2 emissions associated with cement production. This groundbreaking solution is energetically efficient, uses industry standard materials and is economically attractive. At scale, this technology will enable gigaton-level reductions in CO2 emissions via avoidance and capture routes.

Our team is united behind the idea that preventing climate change is the single most important task of this generation. If you are excited about cutting edge science, saving the environment, and want to have fun while doing it, join us!
