GlobalABC Annual Report 2025: 10 years of Global Action for Zero-Emission and Resilient Buildings

In 2025, GlobalABC focused on strengthening the policy, institutional and technical foundations needed to accelerate the transition to a zero-emission, resilient and affordable built environment. Through its global membership of more than 400 members, including 71 countries, the Intergovernmental Council for Buildings and Climate (ICBC), and its Hubs and Action Groups, the Alliance supported governments and stakeholders to advance climate ambition, strengthen enabling environments, and integrate buildings and construction more effectively into national and international climate processes.

A key priority during the year was supporting countries to incorporate buildings and construction into climate planning and policy frameworks. Technical assistance, guidance and stakeholder engagement contributed to progress on NDC development, climate action roadmaps, implementation planning and sector-specific policy development in countries including Bangladesh, Ghana, Kenya and Senegal. GlobalABC also advanced practical tools, recommendations and frameworks on priority topics such as sustainable materials, climate finance, adaptation, procurement, and near-zero emission and resilient buildings.

A major milestone was the operationalisation of the ICBC as the principal political platform for international cooperation on buildings and construction. Through ministerial and technical engagement, governments advanced common priorities, endorsed and acknowledged GlobalABC tools and recommendations, and strengthened international coordination on sector transformation. Complementing this work, GlobalABC's Hubs and Action Groups developed guidance, recommendations and implementation tools while fostering collaboration between governments, industry, financial institutions, academia and civil society.

The Annual Report presents GlobalABC's activities and achievements in 2025 against its strategic objectives and programme priorities. It covers progress in political engagement and international cooperation, national climate planning and policy development, technical guidance and knowledge products, stakeholder collaboration, and implementation support across the buildings and construction sector, reflecting the Alliance's progress over the reporting period and its continued commitment to transforming the sector.

The Near-Zero Emission and Resilient Buildings - Shared Definitions, Indicators, Frameworks, and Policy Guidance for Implementation report was developed under the Buildings Breakthrough Priority International Action on “Standards and Certification”.

This landmark report represents a significant step forward in supporting the global transition towards Near-Zero Emission and Resilient Buildings (NZERBs). It provides a common, practical framework to guide governments, cities, and industry in aligning climate mitigation and resilience objectives across the building sector. Building on the 2025 Interim Report, this final report moves from principles to implementation. It introduces:

• A consolidated definition of NZERBs;
• Core building blocks covering operational and embodied emissions, energy efficiency, low-carbon energy, refrigerants, sufficiency, and resilience;
• A harmonised set of indicators and metrics aligned with existing standards and certification systems;
• Comprehensive policy guidance to support national and local implementation.

The framework emphasises a harmonised yet flexible approach, enabling countries to define targets in line with 1.5°C-compatible pathways, local conditions, and capacities, while improving comparability across jurisdictions. It also promotes a shift toward measured, real-world performance and integrates climate resilience as a central pillar alongside decarbonisation.

The report was developed under the Buildings Breakthrough* –launched at COP28, and coordinated by the UNEP-hosted Global Alliance for Buildings and Construction (GlobalABC)– with technical leadership from the World Green Building Council (WorldGBC). It reflects extensive international consultation and collaboration across governments, industry, and civil society. The Buildings Breakthrough aims to make NZERBs the global norm by 2030, and this report provides a critical tool to help translate that ambition into action.

_{*NB: Following recent governance adjustments within GlobalABC, coordination of the Buildings Breakthrough is now integrated into existing GlobalABC structures. Intergovernmental dialogue is convened through the Intergovernmental Council for Buildings and Construction (ICBC), while progress across priority areas is advanced through GlobalABC working groups and reflected in the NZERB Plan to Accelerate Solutions (PAS). The Buildings Breakthrough was co-led by France and Morocco, endorsed by 29 countries, supported by the European Commission, and engaged over 30 initiatives.}
 

India is witnessing an unprecedented expansion of its built environment, with an estimated 5.7 billion m² of new building stock expected by 2030, and nearly 40% of its population projected to live in cities by 2030. Buildings constructed today will remain in use for decades, making it critical to address emissions across the entire life cycle. The United Nations Environment Programme (UNEP) is supporting India's transition to a circular, low-carbon, and resource-efficient built environment. 

Through enabling frameworks for sustainable materials, the project promotes responsible material use, stimulates local sustainable markets, and helps India raise its climate ambition within the buildings and construction sector, with financial support from the Federal Ministry for Economic Cooperation and Development (Germany) and the SED Fund.

Bangladesh is undergoing rapid urban transformation, driven by sustained economic growth and population expansion. With nearly one-third of its population already living in urban areas, the country's built environment is expanding at an unprecedented rate. By 2030, over 50% of Bangladesh's population is projected to live in cities, significantly increasing the demand for housing, infrastructure, and construction materials. 

To advance this transition, UNEP, in collaboration with UNOPS, UN-Habitat, the Ministry of Housing and Public Works, HBRI, and RAJUK, is promoting the use of sustainable materials and circular economy practices, with financial support from the Federal Ministry for Economic Cooperation and Development (Germany). Through enabling policies and local innovation, the initiative aims to support Bangladesh in building resilient, low-carbon cities aligned with its climate commitments and Vision 2041.

Kenya Buildings & Construction Roadmap provides a shared vision for decarbonising the buildings sector through innovative stakeholder-led bottom up practices, collaboration, partnerships, and accountability. It demonstrates what can be achieved when public and private sectors work together towards a common goal – to create an industry that builds responsibly and sustainably.

The Global Buildings Performance Network are honoured to work alongside Kenya State Department for Public Works, Architectural Association of Kenya, research institutions, and industry partners to accelerate this transformation. By aligning our actions with Kenya’s national goals and focusing on implementable actions and measurable outcomes, we can deliver real change, today and for generations to come.

Report Summary: A lot has changed in real estate sustainability in the past year. A new US administration turned away from climate action as state and local governments leaned in. Europe proposed delaying and scaling back regulations in its Omnibus proposal, while countries like Japan and Singapore introduced disclosure requirements in Asia-Pacific. Data center expansion, electrification, and aging infrastructure are affecting electricity rates while insurers are raising premiums and tightening underwriting standards in response to increasing physical climate risk.

In times of change, communities like ULI Greenprint come to the forefront to help real estate members navigate complexity together. Greenprint brings together sustainability practitioners from 130 real estate companies to "reduce carbon and build value," by sharing best practices, learning together, and building tools to decarbonize their portfolios. Greenprint members understand that decarbonization is not just good for the environment– it's good for business. In the past year alone, Greenprint members have:

• Stayed on top of the latest trends by joining more than 100 Greenprint members-only discussions and webinars on topics ranging from net zero building certifications to innovative social programs.
• Funded ULI research for the industry like the Developer's Guide to Embodied Carbon, Myth-Busting Heat Pumps in Commercial Real Estate, and five primers on net zero tenant engagement.
• Partnered across the value chain on initiatives like ULI developer and utility convenings, the ECHO Project, and the low-carbon steel initiative in China.

The results? Over the past 15 years, Greenprint members have steadily reduced their collective emissions. This year, I am pleased to report that members have achieved a 6 percent reduction in like-for-like and year-over-year carbon emissions. Notably, European assets reported a 13 percent reduction in like-for-like and year-over-year carbon emissions.

In the year ahead, Greenprint will leverage the newly created ULI Impact Lab, which unites ULI's work across sustainability, housing, capital markets, and advisory services, to help members take strategic action on their decarbonization goals. ULI applauds its Greenprint members for continuing to lead the way on decarbonization, and we look forward to another successful year together.

Globally, buildings account for 37 percent of energy and process-related carbon dioxide (CO2) emissions. With increasing urbanization and population growth, demand for energy will continue to increase faster than the supply of renewable energy. This means that increasing the efficiency of current energy use is critical to climate change mitigation efforts while also meeting the development requirement of growing economies. Regulations that can increase the energy efficiency of buildings and reduce the carbon footprint of buildings are thus vital to reducing greenhouse gas (GHG) emissions and to achieving the Paris Agreement’s goal of keeping the increase in average global temperature below 2°C. This checklist aims to facilitate a robust approach to reviewing green building provisions in building regulations by providing a discussion of fundamental green building components of building regulations, and a systematic approach to review green building provisions in regulations.
