An example method of cementing in a subterranean formation includes
determining a settable composition for use in the subterranean formation;
calculating a total carbon footprint of the settable composition;
determining at least one additive for use in the settable composition,
wherein the additive replaces at least a portion of the settable
composition and reduces the total carbon footprint of the settable
composition; preparing the settable composition comprising the additive;
placing the settable composition comprising the additive in the
subterranean formation; and allowing the settable composition comprising
the additive to set in the subterranean formation. Additional embodiments
of the present invention include determining an amount of reduction in
the carbon footprint of the settable composition; and/or communicating
the amount of reduction in the carbon footprint of the settable
composition to a customer or end user.
