In 2024, the Global Alliance for Buildings and Construction (GlobalABC) continued to strengthen its position as the leading global platform for a zero-emission, efficient, and resilient built environment. Membership rose to 339, including 42 countries—with a 19% growth from low- and middle-income countries—while the Alliance expanded its impact through high-level convenings, strategic partnerships, and the launch of the Intergovernmental Council for Buildings and Climate (ICBC). From publishing flagship reports and roadmaps to coordinating COP29’s Buildings Pavilion and mobilizing private sector action, GlobalABC is driving systemic change across the buildings sector worldwide.
