Code and Parts 6 and 11 of Title 24 of the California Code of Regulations. This shall also include the following targets for the decarbonization of newly constructed commercial or residential buildings:

(B) Carbon neutrality by 2045.
(4) A set of feasible implementation measures designed to carry out those goals, policies, and objectives.
(d) At least 45 days prior to the adoption of building decarbonization amendments pursuant to this section, each city and county shall send a copy of its draft amendments to the commission.
