Our journey began with learning that concrete production accounts for 8% of global carbon emissions — equivalent to all the carbon emitted from global food waste. We met climate scientists at Carbon Upcycling Technologies (CUT) who invented a way to make concrete more sustainable by substituting up to 25% of the cement with captured CO2. This breakthrough innovation reduces the amount of carbon-intensive cement needed in concrete while also creating a new way for CO2 emissions to be captured and utilized, rather than released into the atmosphere. If the construction industry universally adopts carbon capture and upcycling technology, we could eliminate up to 862 million tons of CO2 each year.
