The 2024 Building and Climate Global Forum Report serves as a valuable resource for reflection and action in the field of buildings and climate. This major event brought together over 1,500 participants from more than 70 countries, fostering dialogue among international experts, government representatives, and private sector leaders.

With a strong focus on innovation, research, and education, the report captures key insights from the plenary and parallel sessions. A dedicated team of experts, students, and alumni contributed to summarizing discussions, ensuring the dissemination of critical knowledge on sustainable development challenges in the built environment.

This initiative was made possible through the collaboration of ADEME (The French Agency for Ecological Transition), École nationale des ponts et chaussées and the Global Alliance for Buildings and Construction (GlobalABC), and the commitment of nearly 50 rapporteurs, whose contributions played a crucial role in the success of this project. The report stands as a testament to collective efforts in advancing sustainable solutions for the buildings and construction sector.

The Global Status Report for Buildings and Construction (Buildings-GSR), published by the UN Environment Programme (UNEP) and the Global Alliance for Buildings and Construction (GlobalABC), provides an annual snapshot of the progress of the buildings and construction sector on a global scale. The Buildings-GSR reviews the status of policies, finance, technologies and solutions to monitor whether the sector is aligned with the Paris Agreement goals.

The Global Status Report for Buildings and Construction 2024-2025 - Not just another brick in the wall highlights progress made on related global climate goals and calls for greater ambition on six challenges, including building energy codes, renewable energy, and financing. Global frameworks and initiatives such as Intergovernmental Council for Buildings and Climate, the Buildings Breakthrough and the Declaration de Chaillot are sustaining momentum towards adopting ambitious climate action plans, Nationally Determined Contributions (NDCs), for net-zero buildings ahead of the UN Climate Change Conference (COP30) in Belem, Brazil.

Despite this progress, the sector remains a key driver of the climate crisis, consuming 32 per cent of global energy and contributing to 34 per cent of global CO2 emissions. The sector is dependent on materials like cement and steel that are responsible for 18% of global emissions and are a major source of construction waste.

This study, conducted by the engineering, architecture and consultancy firm, Ramboll, in collaboration with leading European researchers from AAU Built and KU Leuven, and funded by Laudes Foundation, puts forward a framework for assessing and monitoring embodied emissions at the building level and a recommended benchmarking process related to European Member States’ carbon budgets.

The Sufficiency Action Hub aims to demonstrate the necessity, feasibility, and social desirability of sufficiency measures in the building sector, fostering a shared understanding across decision-making levels. Its goal is to build a diverse community of stakeholders worldwide, from various sectors of the building value chain, to adapt sufficiency solutions to different contexts, recognizing disparities between the Global North and South. Launched by the French Institute for Building Performance and supported by key institutions like ADEME, the initiative seeks to address the environmental challenges posed by the building sector, which is responsible for 21% of global greenhouse gas emissions. The Action Hub highlights the urgent need for sufficiency measures, advocating for a systemic approach that integrates demand-side policies to reduce resource consumption, mitigate emissions, and ensure social equity. Through international collaboration and the adoption of the "Sufficiency First" principle, the initiative aims to reshape the future of the building sector within planetary boundaries. The Action Hub has recently published a report outlining the key findings of its ongoing work and initiatives.  

Climate Action Roadmaps for Buildings and Construction Bangladesh has been launched by the Ministry of Housing and Public Works, People’s Republic of Bangladesh, on 7 October.

This roadmap follows the Global Alliance for Buildings and Construction (GlobalABC) framework, developed through a partnership between the United Nations Environment Programme (UNEP), the United Nations Human Settlements Programme (UN-Habitat) and the United Nations Office for Project Services (UNOPS). It emphasizes reducing emissions and improving resilience across the entire life cycle of buildings, and sets ambitious short-, medium-, and long-term targets for decarbonizing the built environment, aligned with the Marrakech Partnership for Global Climate Action. The roadmap is centred around four main cross-cutting objectives: (1) zero embodied carbon; (2) zero operational carbon; (3) adaptation; and (4) well-being and inclusion.

Since its launch at COP 26, the Breakthrough Agenda has become established as an annual collaborative process centred around the Conference of the Parties (COP) meetings of the United Nations Framework Convention on Climate Change (UNFCCC). It is currently supported by 59 countries representing over 80% of global GDP, and by over 100 initiatives working to enhance collaboration within major emitting sectors. Countries can endorse Breakthrough goals to make clean technologies and sustainable practices more affordable, accessible and attractive than their alternatives by 2030 in the power, road transport, hydrogen, steel, cement, buildings and agriculture sectors. This report covers six of the seven sectors, with agricultural covered in a separate report.

The Breakthrough Agenda establishes an annual cycle to track developments towards these goals, identify where further coordinated international action is urgently needed to accelerate progress and then galvanise public and private international action behind these specific priorities in order to make these transitions quicker, cheaper, and easier for all.

To initiate this cycle, world leaders tasked the IEA and the UN Climate Change High Level Champions to develop an annual Breakthrough Agenda report to provide an independent evidence base and expert recommendations for where stronger international collaboration is needed.

This document, the 2024 Breakthrough Agenda Report, is the third of these annual reports. It provides an assessment of progress against the recommendations made last year, updating recommendations for what more needs to be done.

This year's report includes the second edition of the Buildings Chapter, developed in collaboration with the GlobalABC. The chapter highlights progress in the built environment and calls on governments to strengthen collaboration, in five priority areas: standards & certification, demand creation,  finance & investment, research & deployment, capacity & skills– to accelerate decarbonisation and enhance resilience in buildings.

The new Finnish Construction Act includes obligations concerning sustainable construction that stress carbon reduction and longevity of buildings. The latter contains a new essential technical requirement concerning the lifecycle performance of a building. The lifecycle performance comprises durability, adaptability and reusability. Thus they also have impacts on the use value and economic value of buildings.

The basic condition for the management of lifecycle performance is that in construction projects precise and verifiable requirements can be set for lifecycle performance. This in turn requires that the lifecycle performance and indicators for them have been defined. The Ministry of the Environment started an expert process in 2022 that aims to further specify the concepts related to lifecycle performance and present a summary and development proposals for the evaluation, planning and guidelines concerning lifecycle performance.

This report presents some of the content produced in the expert process and proposes that, after having been further specified, lifecycle performance should be more systematically incorporated into the procurements and guidance of construction. The report lays the foundation for a systematic approach to lifecycle planning and gives recommendations for further development opportunities related to the topic.

At the end of their service lives, building materials are either recovered (e.g., reused, recycled, incinerated) or disposed of in landfills. In life cycle assessment (LCA) terms, the environmental impacts due to material recovery or disposal are accounted for within the end-of-life (EOL) stage.

Through interviews, a survey, and a workshop, this research explores the functions that existing whole building LCA (WBLCA) tools offer to create models that can best represent EOL processes. This research further explores tool functionalities and data needs and provides recommendations and future research directions to improve EOL modeling in WBLCA tools.

The Global Status Report for Buildings and Construction (Buildings-GSR), a report published by the UN Environment Programme (UNEP) and the Global Alliance for Buildings and Construction (GlobalABC), provides an annual snapshot of the progress of the buildings and construction sector on a global scale. The Buildings-GSR reviews the status of policies, finance, technologies, and solutions to monitor whether the sector is aligned with the Paris Agreement goals. It also provides stakeholders with evidence to persuade policymakers and the overall buildings and construction community to take action.

As outlined in the latest edition, the buildings and construction sector contributes significantly to global climate change, accounting for about 21 per cent of global greenhouse gas emissions. In 2022, buildings were responsible for 34 per cent global energy demand and 37 per cent of energy and process-related carbon dioxide (CO2) emissions.

Policy progress is evident with more comprehensive climate action plans covering buildings and construction in Nationally Determined Contributions (NDCs). However, few align with net-zero operational emissions, and while over 81 countries have building energy codes, many are outdated.Investment in building decarbonisation exceeded US$285 billion in 2022 but is expected to decline in 2023, largely due to a less favourable investment environment due to rising costs. The necessary increase in investments falls short of the net-zero targets for new and existing buildings by 2030 and 2050, respectively.

The 2022 update of the Global Buildings Climate Tracker (GBCT) paints a concerning picture: the gap between the current state and the desired decarbonisation path is significant. To align with the 2030 milestone, an annual increase of ten decarbonisation points is now required, a substantial jump from the six points anticipated per year starting in 2015.

The GBCT shows a negative rebound since 2020 in the decarbonization of the buildings sector, with increased energy intensity and higher emissions. The gap between the actual climate performance of the sector and the necessary decarbonization pathway is widening. The lack of structural or systemic decarbonisation improvement in the building sector leaves its emissions reductions vulnerable to external factors.

To reach the goals of net-zero carbon emission buildings for new buildings by 2030 and existing buildings by 2050, stronger policies are needed to enhance energy efficiency and address carbon emissions from building materials and construction. National efforts are crucial, with countries forming coalitions to share best practices and promote low-carbon construction.

This year, the deep dive chapters are the following: Adaptation and resilient construction methods; Innovations in business cases (renovation and green building construction industry); and Nature-based solutions and biophilic design.

A welcome development in 2023 was the Buildings Breakthrough launched at COP28, to coordinate between countries to make clean technologies and sustainable solutions in the buildings and construction sector the most affordable, accessible, and attractive option in all regions by 2030.

Looking forward to 2024, the focus must be on tangible emission reductions, enhancing building performance, increasing renewable energy use and addressing housing and energy access disparities. Despite the complexities, strategic partnerships can facilitate the shift to an efficient, resilient and whole life net-zero carbon global building stock.

Climate Target Setting for Real Estate Sector Financing’ is the first in a series of publications developed by members of the Net-Zero Banking Alliance (NZBA) with the goal of assisting banks by outlining the choices they make when setting climate-related targets for financing in particular sectors of the real economy. This includes key considerations in relation to the scope, portfolio metrics, data, and scenarios, emerging practices, common challenges and policy, data, and other gaps.

For many banks, the commitment they choose to make when joining NZBA requires them to set sectoral decarbonisation targets for their residential and commercial real estate financing. This publication is aimed at these banks in particular. It does not prescribe any particular methodology for banks to use or impose any requirements on NZBA member banks over and above the ones they chose to commit to when becoming a signatory.
