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.}
