Yes there is. Geopolymer cement provides an 80% reduction in co2 emissions vs traditional cement. CarbonCure has developed a version of concrete that absorbs co2 during its production, though it cannot be poured and can only be used to make prefab shapes [1].
An issue with these new cements is that there is no economic incentive for companies to change production processes and switch.

- tastyfreeze 5y agoIt isnt just cost that prevents a switch. Some building codes explicitly state Portland cement as the allowed material. Geopolymer proponents have been working to change building code to stating required material properties instead. Unsurprisingly, geopolymers have taken off in countries with less regulation.
