Market conditions, technology, and scientific understanding of building decarbonization may evolve Therefore, this primer recommends that statute language to include embodied carbon into C-PACE defineEmbodied Carbon Reduction Improvements in a broadly inclusive manner, minimizing the need forfuture statute amendments addressing embodied carbon. The definition of specific eligible measures, This primer recommends the following amendment to C-PACE enabling statutes, which defines EmbodiedCarbon Reduction Improvements: C-PACE Statute Amendment Embodied Carbon Reduction Improvementmeans any measure that reduces thetotal greenhouse gas emissions associated with the extraction, manufacturing, The ISO 21930 standard defines life-cycle assessment (LCA) modules for embodied carbon correspondingto material manufacturing, construction, operation, and end of life of buildings (see Exhibit 1).3Thisprimer also recommends an LCA scope boundary that includes all emissions within modules A1–A3 for the Program Guideline Pathways This primer recommends a flexible, multi-pathway approach to determining the eligibility and financingterms of specific embodied carbon reduction measures in program guidelines. These pathways build on theCalifornia Green Building Standards Code (CALGreen) (notably, sections 5.105, 5.409, and 5.409.3), and a Leveraging the latest embodied carbon data from the Carbon Leadership Forum (CLF) and others whilemirroring the pathways employed in the above codes ensures that C-PACE embodied carbon guidelinesare based on evidence-backed, market-compatible measurement and reduction methods. This approach Material pathway Applicability: New construction and retrofits This pathway allows developers to cover the hard and soft costs associated with procuring and installinglow-embodied-carbon materials or components in a building. This pathway is applicable to both new To be eligible for financing, a qualified professional (as identified by the C-PACE program) must submit aqualifying environmental product declaration (EPD) for the material or component, and demonstrate thatthis material or component has a global warming potential (GWP) for LCA modules A1–A3 not exceeding Qualifying EPDs EPDs submitted for compliance with the Material Pathway must be Type III (compliant with ISO14025, EN 15804, or ISO 21930) and product specific (covering a specific product) or facility specific For emerging low-embo
