The Catalogue of Climate Solutions for Buildings shows that the transformation of the building sector is not a distant ambition but a reality already underway. Featuring over 90 real-world cases from more than 40 countries across six continents, it demonstrates that deployment is possible today - covering every stage of the building life cycle, from design and construction to operation and end-of-life. It showcases a wide spectrum of technologies, from advanced digital tools and renewable systems to locally adapted, low-tech approaches, alongside the policies, financial mechanisms, and collaborative initiatives that make their implementation possible. Developed by the Solar Impulse Foundation, lead organisation of the UNEP-hosted Buildings Breakthrough initiative, this work is a landmark deliverable for this coalition of over 30 governments and 30 NGOs working to make near-zero emission and resilient buildings the new normal by 2030.

Launched by the Intergovernmental Council for Buildings and Climate (ICBC) at COP30 in Belém on November 11th 2025, this ministerial commitment positions housing affordability and climate sustainability as interconnected priorities.
