Not at any scale that counts. There are a whole bunch of companies _trying_ to make zero carbon cement, but it's all very early stuff.

The lifetime of a cement plant is 30-50 years, and they cost 100-200M Euros to build, so even if there were a process that was ready to scale today, producing a cement that passed regulatory standards, we'd still be making some Portland cement into the 2070s.

Ergo, producers would like to stick a carbon-capture plant onto their kilns.
