The document argues that the real estate industry must move beyond operational energy reporting to include embodied carbon in Scope 3 climate disclosures. It highlights increasing pressure from major investors like BlackRock and CalPERS, as well as potential SEC regulations, to standardize these disclosures. The guide recommends transitioning from spend-based to mass-based emissions accounting using Environmental Product Declarations (EPDs) and life-cycle assessments (LCA) to accurately track up-front emissions from building materials.

The guide explains how Environmental Product Declarations (EPDs) function as 'nutrition labels' for building materials by reporting life-cycle assessment (LCA) data, specifically Global Warming Potential (GWP). It argues that current EPDs suffer from inconsistencies due to varying data sources and proprietary datasets. To achieve an 'ideal EPD' that supports fair carbon reduction policies, the author recommends that Product Category Rules (PCRs) mandate facility-specific data, limit product variation within single reported values, and require supply-chain-specific data for upstream processes. The document also identifies barriers to adoption, such as high up-front costs for small businesses and the lack of a universal public database, while noting US government initiatives like the EPA's grant program and the Inflation Reduction Act of 2022 aimed at advancing EPD development.

Nigeria faces a significant housing shortage of 17 million units, with a projected need for 700,000 units annually by 2050. The report finds that the policy environment for net zero carbon buildings is fragmented, lacking an overarching national strategy. While some financial instruments like concessional loans and green bonds are well-established, many others remain nascent or unused. The most severe barriers are political (lack of regulations and standards) and financial (lack of affordable finance and awareness of funding). The report recommends five priority areas: embodied carbon and materials, appliances and lighting, cooling, electricity generation, and clean cooking, proposing specific financial and policy pathways to scale these solutions.

The report identifies clinker production as the primary source of emissions in the cement sector, accounting for 88% of total emissions. It evaluates three main decarbonization levers: substituting clinker with materials like fly ash and calcined clay, replacing coal and gas with biomass, waste, or green hydrogen, and deploying CCUS. While some progress is noted in developed markets, the report warns that absolute emissions will rise as production grows in emerging markets like India and Africa unless green processes are scaled. Key barriers include supply constraints for substitutes, high upfront costs for CCUS, and a lack of carbon transport infrastructure in high-growth regions.

The document discusses the shift from territorial to consumption-based emission tracking in Nordic municipalities to capture embodied emissions from imported goods and services. It highlights that imported embodied CO2 emissions in final consumption ranged from 45% in Finland to nearly 60% in Iceland in 2015. The brief identifies data collection across value chains as a primary challenge and notes that the Greenhouse Gas Protocol for cities (GPC) lacks detailed guidance for comprehensive consumption-based assessments.

The document argues that city officials face challenges in building decarbonization due to inconsistent definitions of Net Zero-Energy Buildings (NZEBs) and Zero-Carbon Buildings (ZCBs). It highlights that NZEBs often neglect embodied emissions—those released during material extraction, construction, and demolition—and advocates for the use of carbon-based life-cycle assessments (LCA) to achieve true zero carbon emissions. The guide recommends specific LCA tools such as openLCA, One Click LCA, Tally, and the EC3/Embodied Carbon Calculator, while noting that technical expertise and data quality remain barriers. Additionally, it lists several global resources and policy toolkits, including the Global Roadmap for Buildings and Construction 2020-2050 and the Carbon Leadership Forum Policy Toolkit, to help cities implement regulatory, economic, and fiscal instruments for decarbonization.

The document outlines the technical framework for certifying low-carbon buildings under the Climate Bonds Standard. It shifts the focus from energy use intensity to emissions intensity, establishing city-specific linear trajectories aimed at net-zero carbon emissions by 2050. The criteria distinguish between new and existing buildings, introducing mandatory Whole Life Carbon Assessments (WLCA) for new constructions to account for embodied carbon. It also provides a guide for Scope 3 GHG accounting across the building value chain, from manufacturers to owners and deconstruction firms.

The document examines the challenges of implementing border carbon adjustments (BCAs), focusing on the need for international cooperation to standardize embedded emissions calculations, determine geographical exemptions, establish credits for foreign climate policies, and decide on the use of revenues. It evaluates various multilateral, regional, and bilateral venues for these discussions, noting that while the WTO is a primary site of tension, substantial multilateral progress is currently lacking.

The guide describes 'book and claim' as a flexible chain of custody model where producers 'book' emissions savings from clean fuels or materials in one location, and customers 'claim' those benefits for climate disclosures elsewhere via certificates. This system is designed to channel finance into nascent decarbonization technologies, such as sustainable aviation fuel (SAF), by allowing corporations to cover the price premium of cleaner alternatives when physical offtake is impractical. To ensure accountability, the system relies on independent verification of the physical supply chain, the use of registries to prevent double counting, and adherence to standardized reporting guidelines.

The document argues that the steel and cement sectors in India are 'hard-to-abate' and require coordinated government, industry, and financial action to avoid carbon lock-in. Because breakthrough technologies (TRL 5-9) are currently commercially unviable and increase production costs—by up to 45% for steel and 80% for cement—market forces alone cannot drive their adoption. The authors recommend a policy mix of carbon pricing, public funding for demonstration pilots, capex subsidies, green public procurement, and embodied-carbon standards. Additionally, the brief emphasizes the need for a supporting enabling environment, including CO2 and hydrogen infrastructure, streamlined permitting, and concessional finance from international sources.

New home construction in the US generates over 50 million tons of embodied carbon emissions annually. Analysis of 921 model homes across the US, Canada, and Europe indicates average cradle-to-gate emissions of 184 kg CO2e/m2. Reductions of 30% to 50% are achievable using existing, cost-parity materials by targeting concrete, insulation, cladding, and interior surfaces, which comprise over 70% of total emissions. Further reductions up to 140% are possible through low-emitting and carbon-storing materials.

Embodied carbon, which accounts for 11 percent of global greenhouse gas emissions, refers to the emissions released during the lifecycle of building materials. Reduction strategies include using carbon-storing materials like mass timber, adopting 3D printing and robotic automation, and implementing material efficiency through modular construction. In the US, the Inflation Reduction Act provides nearly $10 billion for reducing embodied carbon, while several states have adopted 'Buy Clean' laws. RMI research indicates that low-cost embodied carbon solutions can reduce emissions by 19 to 46 percent with cost premiums under 1 percent.

The report argues that transitioning from a "take, make, waste" economy to a circular one is essential for Canada to meet its climate targets, as energy transitions alone cannot address emissions from resource extraction and material use. It identifies significant emissions-reduction opportunities in the metals, construction, plastics, and food sectors, while noting that Canada is currently at a nascent stage of implementation compared to leaders like Japan and the European Union. The document emphasizes that 'upstream' measures—such as demand suppression, product life extension, and smarter design—offer greater climate benefits than downstream recycling. It highlights critical barriers in Canada, including opaque material flow data, regulatory hurdles for recycled aggregates, and a lack of comprehensive national circularity goals. The report recommends that Canada develop a formal roadmap, integrate circularity into its Nationally Determined Contributions, and utilize tools like carbon pricing and green public procurement to incentivize the shift.

The document examines how selecting materials with low embodied carbon or carbon-storing properties during building retrofits can prevent emissions spikes and transform buildings into carbon sinks. It analyzes exterior insulation systems and affordable multifamily housing projects in the Northeast to demonstrate that sustainable material substitutes are currently available to help meet 2030 decarbonization goals.

The document examines the gap between EU Green Public Procurement (GPP) targets and actual implementation in eight Member States. It identifies systemic barriers—including fragmented governance, lack of standardized data, and limited procurement officer capacity—while highlighting successful local and national initiatives in Sweden, France, Germany, and others. The brief argues that the EU must harmonize reporting, institute mandatory requirements for high-emitting sectors, and provide better technical support to leverage public spending for climate goals.

The report finds that Green Public Procurement (GPP) in the EU is characterized by a fragmented approach with few binding requirements and significant gaps between national climate targets and actual procurement practices. While some regions like Catalonia and cities like Berlin show high ambition, most Member States rely on voluntary guidelines. The construction and road transport sectors are highlighted as high-impact areas where GPP could drive decarbonization, yet implementation is hindered by a lack of standardized data, insufficient capacity and time for procurement officers, and a lack of mandatory EU-level criteria. The report recommends harmonizing GPP definitions, introducing mandatory carbon criteria, and expanding the scope of EU Directives to include embedded emissions.

The briefing proposes a phased framework for building decarbonization—moving from efficiency to electrification, renewable energy, and finally the removal of embodied carbon—to reach absolute zero. It argues that because the necessary technologies already exist, the primary barrier is cost and adoption speed. By performing segmentation analysis on real estate subsegments, such as large commercial office buildings, financial actors can provide targeted interventions that drive demand, push technologies up their learning curves, and lower prices for the broader market.

The document outlines four strategic propositions for Sweden's 2023 EU presidency: ensuring energy crisis responses align with long-term climate goals, integrating enforceable sustainability standards into trade agreements, promoting 'just resilience' to address transboundary climate risks, and establishing an EU-wide approach to monitoring consumption-based emissions.

The document highlights that building operations and construction account for approximately 40% of India's energy use and warns that consumption could triple by 2050 without intervention. It proposes a whole-system approach—integrating low-carbon design, reduced energy needs, efficiency, and clean energy supply—to potentially reduce buildings-related emissions by a factor of four by 2050 compared to business-as-usual scenarios.

The report argues that India's buildings sector must adopt an integrative whole-system approach to address both embodied and operational emissions. It highlights that building operations account for about a third of India's energy use, and without intervention, energy consumption could triple by 2050. The proposed framework prioritises reducing energy needs through passive design, serving those needs with super-efficient equipment, and transitioning to clean energy procurement and demand flexibility. Key recommendations include government mandates for net-zero public buildings, the adoption of carbon accounting for corporations, and the implementation of building performance standards to ensure actual operational efficiency.
