Introducing the world's first carbon-negative Portland cement

We're building a new foundation for the climate era. Cement is responsible for about the same amount of greenhouse gas emissions as all of the cars on the road today. Cement has been one of the most difficult materials to decarbonize, until now. 


We have invented a way to make carbon negative Portland cement that is identical to conventional cement and lower in cost. Simply put, our process will turn one of the most intractable climate problems into a carbon negative climate solution.
