"We're taking CO2 out of the system" says carbon-capturing concrete maker Carbicrete

Montreal company Carbicrete has developed a method for sequestering carbon in concrete, claiming its product captures more carbon than it emits.The technology cuts out the need for calcium-based cement, a key ingredient in traditional concrete that is responsible for around eight per cent of all global CO2 emissions.
"It's negative emissions," Carbicrete CEO Chris Stern told Dezeen. "We're taking CO2 out of the system every time we make a block."
