World / Americas Concrete steps made in US fight against carbon emissions Carbon-injected concrete, that traps carbon dioxide, will be used in Hawaii, and possibly other US cities, in concrete construction from now on BL PREMIUM

New York — Hawaiian officials have taken a concrete step to fight climate change: they plan to lock planet-warming carbon dioxide (CO2) up in the concrete they use for road construction.

Hawaii’s department of transportation will use carbon-injected concrete from now on when it constructs concrete projects — including a new structure to protect a highway tunnel from rockfalls, said the government body’s spokesperson Shelly Kunishige. “It allows us to use less cement in our mixes. So we reduce the carbon footprint of our building.”
