1. A method of producing a cement composition with reduced carbon emissions comprising:

(a) defining cement constraints comprising at least one cement property;

(b) calculating a set of cement compositions which satisfy the cement constraints, using cement property models corresponding to the cement constraints;

(c) calculating a carbon emission associated with each of the cement compositions in the set of cement compositions using a carbon footprint model;

(d) selecting a cement composition from the set of cement compositions; and

(e) preparing the cement composition selected in step (d).
