Global Status Report for Buildings and Construction - Beyond foundations: Mainstreaming sustainable solutions to cut emissions from the buildings sector
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.
Sustainable construction is moving beyond materials, certification and compliance towards climate-resilient infrastructure judged by whole life carbon, life cycle cost and real-world performance. The funding debate around sustainable drainage systems shows why environmental sustainability in construction now depends on treating SuDS, wetlands and green infrastructure as core assets, not optional landscaping. Properly designed drainage can reduce flood risk, manage drought pressure, limit polluted runoff and support sustainable urban development, making lifecycle assessment and building lifecycle performance central to investment decisions.
Water security is becoming a defining test for sustainable building design, eco-design for buildings and low carbon design. Built environments designed to remove winter rainfall at speed are increasingly exposed to summer scarcity, heat stress and nutrient pollution. Whole life carbon assessment must sit alongside resilience modelling, maintenance planning and resource efficiency in construction if projects are to deliver net zero whole life carbon outcomes rather than narrow carbon footprint reduction claims.
Coastal defence work at Ventnor underlines the need for site-specific adaptation as unstable cliffs, rising seas and heavier rainfall challenge historic engineering assumptions. The strongest sustainable design approach will combine hard protection with nature-based systems, circular construction strategies and low-impact construction, reducing the carbon footprint of construction while improving long-term resilience. Embodied carbon, embodied carbon in materials and sustainable material specification will be decisive as clients compare low embodied carbon materials, green building materials, renewable building materials and environmental product declarations (EPDs).
Data centres are emerging as a major pressure point for green construction. Reports linking AI infrastructure to nitrogen oxide emissions from temporary gas turbines, combined with concern over cooling demand, show how energy-intensive buildings can undermine net zero carbon ambitions. Future briefs for energy-efficient buildings and low carbon building assets must prioritise grid capacity, low-carbon backup power, heat reuse and water-efficient cooling from the outset.
The direction of travel is clear: sustainable building practices, circular economy in construction and life cycle thinking in construction are becoming commercial necessities. BREEAM, BREEAM v7 and wider green building products standards will remain useful, yet the market is shifting towards measurable outcomes: net zero carbon buildings, carbon neutral construction, end-of-life reuse in construction and decarbonising the built environment across every stage of design, delivery and operation.
