The report argues that electrifying household energy use—specifically through electric vehicles (EVs), heat pumps, and electric appliances—is the most cost-effective path for Canada to reach net zero emissions. While electricity prices have remained more stable than volatile fossil fuel prices, the transition requires government intervention to overcome upfront costs and infrastructure gaps. Modelling suggests that by 2050, electricity could meet 73% to 91% of residential heating loads and over 96% of total vehicle kilometers travelled. To support this, the report recommends policies to increase consumer uptake and a massive build-out of clean electricity generation, which may need to double or triple by 2050.

The study finds that full implementation of decarbonisation strategies for Estonia's residential buildings could reduce annual greenhouse gas emissions by up to 95% compared to 2020 levels. While embodied emissions from renovations are minor relative to energy savings, the overall success of these measures depends heavily on the carbon intensity of grid electricity; if the current fuel mix for electricity and district heating remains unchanged, comprehensive renovation could potentially increase emissions compared to the baseline.

Buildings account for 18% of Canada's GHG emissions, with residential space heating as the primary energy driver. The document argues that deep energy retrofits (DERs)—defined as achieving a minimum 50% reduction in energy consumption—are essential for net-zero targets. While high upfront costs are a barrier, the green building industry could contribute CAD 150 billion to the economy by 2030, with annual energy bill savings estimated at CAD 10.8 billion. The brief recommends adopting the highest tier of the National Building Code, implementing innovative financing like Property Assessed Clean Energy (PACE), and scaling prefabricated retrofit models like Energiesprong.

The document argues that Ukraine's reconstruction presents a 'watershed moment' to build a climate-resilient society, specifically through energy-efficient residential building. It warns against the 'international technocracy' and corruption seen in Bosnia and Herzegovina's recovery and the implementation delays and inefficient grant usage observed in Croatia's post-earthquake reconstruction under the NextGenerationEU program. The author analyzes the EUR 50 billion Ukraine Facility and the Ukraine Plan, suggesting a targeted funding strategy where grants are prioritized for cost-effective multi-family homes to reduce payback periods and attract investors, while low concessional loans are used for single-family homes.

RMI's analysis of US building emissions reveals that building operations account for 23% of annual carbon emissions, with single-family homes (58%) and commercial buildings (37%) being the primary contributors. The report argues that current green capital flows are insufficient and should be redirected from large commercial buildings toward the retrofit of existing buildings, specifically targeting single-family homes and small-to-medium commercial properties to achieve meaningful climate goals.

The document explains the eligibility and certification process for Low Carbon Buildings Bonds, detailing the pathways to achieve net-zero by 2050 and the specific requirements for new and existing buildings. It outlines the use of trajectories and proxies to measure emissions intensity and highlights new 2023 requirements for new buildings, including the prohibition of fossil fuels and mandatory Whole Life Carbon Assessments.

The document outlines the benefits and application of the Climate Bonds Initiative's certification for commercial and residential buildings in Tokyo and 16 other Japanese cities, aiming for a zero-carbon future by 2050.

The report highlights a 'double threat' in Northern Canada: inadequate existing infrastructure and a climate warming three times faster than the global average. Permafrost thaw is causing significant structural damage to runways, roads, and residential buildings, which threatens essential services like healthcare and food security. The authors argue that while incremental adaptation (e.g., thermosiphons) can delay costs, 'transformational adaptation'—repensuring how services are delivered and where infrastructure is located—is necessary to address systemic deficits rooted in colonial history. The report recommends federal funding restructuring, improved regional climate risk data, and updated building codes to ensure long-term resilience.

The document examines the socio-economic risks associated with the EU's 'Fit for 55' package, specifically the introduction of ETS2. It argues that carbon pricing alone is insufficient to drive decarbonization and may disproportionately affect low-income rural households. While the Social Climate Fund provides a mechanism for compensation and investment, the authors suggest a broader approach including digitalization, subnational capacity building, and structural inequality reforms is necessary for a fair transition.

The study analyzes 122 trials across 25 countries to evaluate interventions for reducing residential energy consumption, finding that while both monetary and non-monetary tools are effective, monetary incentives generally yield more pronounced results.

Sustainalytics has provided a pre-issuance verification letter confirming that PKO Bank Hipoteczny SA's green covered bond framework aligns with the Climate Bonds Standard Version 2.1. The bond is intended to finance or refinance a portfolio of residential green buildings in Poland, targeting the top 15% of low carbon buildings or those achieving significant carbon emission reductions through upgrades.

The document discusses the role of government-sponsored enterprises (GSEs) Fannie Mae and Freddie Mac in addressing the high energy costs faced by 35 million low- to moderate-income (LMI) households in the US. Under the Housing and Economic Recovery Act of 2008, these GSEs have a 'Duty to Serve' underserved markets. With advocacy from the Rocky Mountain Institute (RMI), the GSEs have incorporated energy and water conservation into their 2018-2020 action plans. Key initiatives include Freddie Mac's study on the impact of energy efficiency on loan performance and home valuations, and Fannie Mae's updates to its HomeStyle® Energy product to allow for energy improvements and disaster resilience upgrades.

Multiconsult Norge AS conducted a post-issuance verification of SpareBank 1 Boligkreditt's (SpaBol) EUR 1 billion green bond, concluding that the issuance conforms to the Climate Bonds Standard Version 2.1. The bond finances and refinances a mortgage pool of energy-efficient residential buildings in Norway. Eligibility is based on compliance with Norwegian building codes TEK07 (for houses) and TEK10 (for apartments) or later, which represent the top 15% most energy-efficient buildings in the country. The verifier found that the value of eligible mortgages in the portfolio is approximately twice the size of the EUR 1 billion bond issuance.

The report finds that while Estonia's building sector is relatively well-controlled due to existing regulations, a 19% further reduction in energy consumption is needed to meet 2030 EU targets. In contrast, the transport sector's energy demand is projected to grow by 18% by 2030 under business-as-usual conditions, failing both national and EU targets. The most effective interventions identified are large-scale building shell renovations and the adoption of fuel-efficient, electric, and hybrid vehicles.

The document provides executive summaries of national reports for Bulgaria, Estonia, Germany, Greece, Italy, Serbia, and the UK. It evaluates various energy efficiency scenarios—including Business as Usual (BAU) and those incorporating the impact of socio-economic barriers—using LEAP modelling and a Decision Support Tool (DST). The analysis consistently shows that while ambitious energy efficiency measures can meet EU targets, the presence of socio-economic barriers significantly reduces potential energy savings and GHG reductions across most studied countries and sectors.

The study finds that energy-efficient homes in Spain command a price premium between 5.4% and 9.8% compared to less efficient dwellings. Using a sample of 1,507 homes, the authors determined that homes rated A, B, or C have a 9.8% premium, while those rated A through D have a 5.4% premium. The research also highlights a significant lack of energy efficiency in the Spanish housing stock, with 52% of the sample rated E and nearly 25% rated F or G.

The report estimates that making Uganda's infrastructure climate-resilient will cost between US$52-66 million annually by 2020, rising to US$638-1,157 million by 2050. Residential buildings are the most affected sector, accounting for approximately half of all adaptation costs. The study also projects that annual damages from extreme events, if frequency doubles every 25 years, could reach US$738-3,294 million by 2050. Key adaptation priorities include climate-proofing public buildings and developing resilient transport standards.

The report evaluates the design of proposed tax incentives for residential thermal retrofits in Germany, focusing on whether to support single or comprehensive measures, the appropriateness of the KfW 85 standard, the optimal timeframe for project completion, and the risks associated with stepwise implementation. Based on a survey of 78 practitioners, the document argues that comprehensive retrofits are superior for energy savings and comfort, and that a 10-year flexibility period for completion is unnecessary. It also highlights the critical importance of a specific sequence of measures to avoid structural damage and cost increases.

The report examines the gap between Germany's thermal retrofit targets and current progress, identifying that the retrofit rate for residential outer walls is approximately 0.8% per year against a 2% target. It argues that deep retrofits are most economically viable when integrated into general building renovations. The analysis breaks down the homeowner decision process into three stages—encouraging interest, planning/deciding, and implementation—and maps corresponding policy instruments including information tools, KfW financial incentives, and contractor certification.

The study finds that while awareness of EPCs is high, they play a limited role in German home purchasing decisions due to low availability, a lack of trust, and a failure to provide the financial information purchasers value most.
