Last week I had an interesting phone conversation with Daniel Green at BASF regarding EPDs for concrete. As the NRMCA has am industry EPD that covers most if not all of the ready mix plants in the US. In speaking with Daniel, BASF can provide ways of reducing the carbon foot print for your project by 30 to 70 percent. It may be advantageous to contact Daniel at daniel.r.green at BASF.com for further information.
Good Luck
