(4) (A) By July 1, December 31, 2029, the state board shall evaluate the feasibility and cost impact of achieving the interim target established under paragraph (2). (3).
The state board may adjust the interim target upward or downward to reflect technological advancements and progress in addressing barriers to the deployment of greenhouse gas emissions reduction technologies and processes in the manufacturing of building materials.
(B) If the state board reduces the interim target of 20-percent net reduction established under paragraph (2), (3), the state board shall document the feasibility and cost impact constraints the state board has identified and recommend measures and actions, including proposed statutory changes, necessary to overcome those constraints to enable the building sector to achieve a 40-percent net reduction in emissions of greenhouse gases of building materials as soon as possible,
but no later than December 31, 2035.
(b) The framework developed pursuant to subdivision (a) shall include both of the following:
(1) A requirement for the submission by an entity undertaking the construction of a project with a minimum size of five new residential units or 10,000 square feet of nonresidential building space of a life-cycle assessment, as defined in the International Organization for Standardization (ISO) 14040 series of standards with a focus on the Product Stage phases (A1-A3), to determine the carbon intensity of the materials used in new residential and nonresidential buildings.
(2) A requirement for the submission by the manufacturer of a building material of an Environmental Product Declaration, Type III, as defined by the International Organization for Standardization (ISO) Standard 14025, or
similarly robust life-cycle assessment methods that have uniform standards in data collection consistent with ISO Standard 14025, industry acceptance, and integrity for construction materials used for the building. The state board shall determine how to proceed in the event that insufficient life-cycle assessments or Environmental Product Declarations exist, or in the event of significant supply chain issues.
(c) The framework developed pursuant to subdivision (a) may include a tracking and reporting mechanism that would facilitate the achievement of the goals set forth in this section. Except for a fee to reimburse the state board for any administrative costs incurred in administering the reporting mechanism, the state board shall not impose any other charges on the participants in the reporting mechanism authorized under this subdivision.
(d) Based on the information submitted
by an entity undertaking the construction of a covered project pursuant to paragraph (1) of subdivision (h), the state board shall evaluate the cost impact and feasibility of implementation, and establish a system for addressing known cost impact and feasibility issues in strategy implementation.
(e) As used in this section the following terms have the following meanings:
(1) “Feasibility,” in regard to the use of a material, means all of the following:
(A) The material is capable of being installed in a successful manner within a reasonable period of time, taking into account economic, environmental, legal, social, and technological factors.
(B) The material does not harm the health or safety of those who install the materials or occupy the
building.
(C) The building using the material can be designed to provide an equivalent function and and, at a minimum, the same useful life, performance, and durability as the building made with baseline materials.
(D) The material is commercially available to the region of the project.
(E) The material has not been involved in a claim for a construction or design defect, breach of express or implied warranty, fraud, or misrepresentation.
(F) The material provides an equivalent function and at least the same useful life, performance, and durability as the baseline
material.
(2) (A) “Cost impact” means a significant overall material or operational cost increase or schedule delay resulting from incorporating the lower carbon material.
(B) As used in subparagraph (A), “significant” means an increase of 5 percent or more in the operational or overall material cost at the location of the project or time schedule delay that is attributable to incorporating a lower carbon material compared to the baseline material for which it is a substitute in the project. For purposes of this paragraph, the baseline material shall be the material that would have been used by the entity undertaking the construction of the project if this section did not apply to the project at the time the application for the building permit is submitted for a model home or project pursuant to subdivision (h).
(f) The state board shall allow the entity undertaking the construction of a project to use the same persons as those responsible for the Certificate of Installation pursuant to paragraph (3) of subdivision (a) of Section 10-103 of Title 25 of the California Code of Regulations in submitting, reporting, notifying, tracking, or otherwise conveying information to the state board.
(g) The targets established by this section shall begin to apply no sooner than January 1, 2027. The applicable target for each residential unit built within a project shall be the target that applied at the time the application was submitted for a building permit of the first model home in the project. For projects that do not use model homes, the applicable target shall be the target in effect at the time of submission of the application for the building permit.
(h) (1) The incorporation of lower carbon materials shall be limited or excluded to the extent that it has a cost impact or is unfeasible. If the entity undertaking the construction of a project finds that it is unable to achieve the applicable target due to unfeasibility or cost impact and there are no alternative materials or methods that are feasible and without cost impact that would allow the project to achieve the target, then the project shall be deemed to comply with the applicable target. In such a case, the entity undertaking the construction of a project shall provide the state board with information that explains the steps they took to meet the target and why they were unable to meet the target.
(2) (A) The state board shall form and maintain a technical advisory committee composed of representatives of building product
manufacturers, builders, and design professionals. The technical advisory committee shall review information submitted pursuant to paragraph (1).
(B) After the entity completes the project, the technical advisory committee shall make recommendations to the entity on what steps it could take for future similar projects that would increase the entity’s ability to meet the target.
(C) The state board and the technical advisory committee shall not have the authority to approve, deny, or delay the planning, use, development, design, or construction of a project.
(i) The provisions of this section do not apply to appliances.
(j) For purposes of the California Environmental Quality Act (Division 13 (commencing with Section 21000) of the Public Resources Code),
no adverse environmental impact associated with the manufacture of building materials may be attributed, directly or indirectly, to the project incorporating the building material. This subdivision does not relieve the entity undertaking the construction of a covered project from complying with any other provision within this section.
(k) The state board shall do both of the following:
(1) Research and prioritize actions and provisions that leverage state and federal incentives, where applicable, to reduce costs of implementing greenhouse gas emissions reduction technologies, processes, and materials used in construction-related projects for the construction industry, homeowners, and developers, and to increase economic value for the state.
(2) Evaluate measures to support market demand and financial incentives to
encourage the production and use of materials used in construction-related projects with low greenhouse gas intensity, including, but not limited to, consideration of both of the following measures:
(A) Measures to expedite the adoption for use in projects undertaken by state agencies, including the Department of Transportation and the Department of General Services.
(B) Measures to provide financial support and incentives for research, development, and demonstration of technologies to mitigate emissions of greenhouse gases from the manufacture of materials used in construction-related projects, with the objective of accelerating commercial availability of those technologies.
