Global Status Report for Buildings and Construction - Beyond foundations: Mainstreaming sustainable solutions to cut emissions from the buildings sector

United Nations 5 months ago

The Global Status Report for Buildings and Construction (Buildings-GSR), published by the UN Environment Programme (UNEP) and the Global Alliance for Buildings and Construction (GlobalABC), provides an annual snapshot of the progress of the buildings and construction sector on a global scale. The Buildings-GSR reviews the status of policies, finance, technologies and solutions to monitor whether the sector is aligned with the Paris Agreement goals. 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.

Financial institutions are accelerating sustainable construction by aligning lending with measurable environmental performance. Santander UK’s decision to adapt mortgage models for Octopus Energy’s Zero Bills homes integrates credit policy with energy-efficient buildings, translating net zero carbon ambitions into mainstream financial metrics. This shift signals the emergence of whole life carbon assessment as a determinant in property valuation and positions embodied carbon and life cycle cost analysis as standard tools of risk management across the sector.

Digital transformation is amplifying the movement. The Monklands digital hospital project in Scotland demonstrates how offsite manufacturing, lifecycle assessment and connected data platforms enhance building lifecycle performance, minimise waste, and verify embodied carbon in materials. Durham’s adoption of digital planning and assessment tools reflects a broader drive toward resource efficiency in construction and environmental sustainability in construction. Together these initiatives redefine sustainable building design by embedding whole life carbon accountability into design and delivery workflows.

Policy remains an enabling force but the centre of momentum is shifting from government mandates to operational proof. A renewed national emphasis on green affordability and the integration of social equity with decarbonising the built environment are reinforcing the transition toward net zero whole life carbon outcomes. These developments illustrate a maturing circular economy in construction where sustainable building practices, low carbon design and eco-design for buildings converge to deliver verifiable carbon footprint reduction. The industry’s direction is now measurable—kilograms of CO₂, minutes saved, resources reused—evidence that green construction is evolving from aspiration to tangible low carbon building performance.
