The Global Status Report for Buildings and Construction 2024-2025 - Not just another brick in the wall highlights progress made on related global climate goals and calls for greater ambition on six challenges, including building energy codes, renewable energy, and financing. Global frameworks and initiatives such as Intergovernmental Council for Buildings and Climate, the Buildings Breakthrough and the Declaration de Chaillot are sustaining momentum towards adopting ambitious climate action plans, Nationally Determined Contributions (NDCs), for net-zero buildings ahead of the UN Climate Change Conference (COP30) in Belem, Brazil.
Despite this progress, the sector remains a key driver of the climate crisis, consuming 32 per cent of global energy and contributing to 34 per cent of global CO2 emissions. The sector is dependent on materials like cement and steel that are responsible for 18% of global emissions and are a major source of construction waste.
This report underscores the urgency of harmonizing building codes, scaling low-carbon materials, increasing equitable access to green financing and incentivizing circular construction. Workforce development programmes must also prioritize filling skill gaps while fostering gender diversity in green construction leadership roles. Moreover, stronger global coordination and accountability mechanisms such as the G20’s Voluntary Action Plan to double energy efficiency by 2030 are critical to accelerating progress.
