are estimated to contribute to 11% of all global energy-related carbon emissions.1 While currently this figure is less than the 28% of global carbon emissions attributed to building energy  \nuse, it is estimated that, due to the rapid growth of new construction needed to meet the demand of growing populations, nearly half of the total carbon emissions from new construction from now until 2050 will be attributable to the embodied carbon of our built environment.2  \nWhile there has been extensive focus on policies addressing decarbonization of industrial materials and separately on addressing energy use in buildings, these policies reduce material production emissions and operational emissions. Additional policies are needed to reduce the balance of whole building emissions affected by design and construction practices. The goal of this study was to fully synthesize the broader technology and policy landscape relevant to embodied carbon in buildings.  \nThe study chose to focus on the state of California and local governments within the state, which allows the assessment to consider feasibility more practically and specifically. California was chosen due to its capacity, leverage, and track record for lowering barriers and risks for others in the nation and around the world.  \nSurely enough, legislative movement around embodied carbon in California is rapidly developing. Assembly Bill (AB) 2446, signed into law in 2022, directs the development of a framework for measuring and reducing the average carbon intensity of building materials with a target set of 40% reduction by 2035. Meanwhile, the public sector in California has shown market leadership in low carbon material procurement through the landmark bill AB 262, known as the Buy Clean California Act. Most recently, the California Building Standards Commission voted unanimously to adopt embodied carbon requirements into the state’s green building code, known as CALGreen.  \nA wide range of strategies can be deployed to reduce embodied carbon in the built environment, encouraged by policy action. This study looked first at different types of available strategies and estimated the relative  \nproportion of embodied carbon they could reduce. The strategies were then mapped against different types of building-sector policies.  \nFor the first task, Arup quantified the reduction potential of various strategies through 2045,  \nwhich is the net zero target date for the state of California. Embodied carbon reduction strategies in buildings were categorized as those that are implemented at the project scale, building system scale, or procurement (material) scale. Strategies to optimize the project were determined to have the most reduction potential in the short term while strategies to optimize procurement (i.e., material-level reductions) had the most reduction potential in the long term. This is because many of the technologies to decarbonize material production are slower to scale. In contrast, strategies to optimize the project that focus on b","cbCainLf8w99RfyT","https://ap.wps.com/l/cbCainLf8w99RfyT","pdf",935846,55,"English","# Executive summary\n## Quantifying embodied carbon and urgency\n## Policy and technology synthesis for California\n## Strategy types and reduction potential\n## Linking strategies to policies and building codes\n## Recommendations and implementation levers","[{\"question\":\"What is the key focus of the embodied carbon reduction roadmap for California?\",\"answer\":\"It focuses on identifying strategies and policies to reduce embodied carbon from materials used in buildings, synthesizing the relevant technology and policy landscape for the state of California.\"},{\"question\":\"Why does the report emphasize both project-scale and procurement/material-scale strategies?\",\"answer\":\"It finds project-scale optimization has the greatest near-term reduction potential, while procurement/material-scale measures have the largest long-term potential because decarbonizing material production technologies typically take longer to scale.\"},{\"question\":\"How does the report connect strategy evaluation to building codes?\",\"answer\":\"It maps strategies to policy types and explains that building-focused approaches using whole building life-cycle assessment and material-focused approaches using environmental product declarations can be integrated into building codes, with mid-cycle CALGreen changes already underway.\"}]","Embodied carbon reduction roadmap - Executive summary - September 2023 | PDF",1791015284,139]
