Local Solutions for Green Buildings and Constructions

This first report from the Global Alliance for Buildings and Construction (GlobalABC) Subnationals Action Group focuses on the importance of localizing climate action. It highlights how subnational governments, in collaboration with national authorities, the private sector, and civil society, can drive meaningful change by integrating sustainability, resilience, and circularity into building policies and practices.

With more than half of the global population living in urban areas—and this figure expected to rise—the report examines how cities and local governments are well-positioned to implement climate-responsive solutions. It explores opportunities for multilevel governance, sectoral linkages, and inclusive planning, offering examples and recommendations to support a just and equitable transition.

The report also underscores the need for investment and innovation to scale up efforts, reduce emissions across the building life cycle, and ensure access to safe, affordable, and sustainable housing. It calls for a holistic, people-centered approach to decarbonization and resilience in the built environment—grounded in informed choices, coordinated action, and strong partnerships.
