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.
Britain’s sustainable construction agenda is being reshaped by two tests: whether major infrastructure can prove credible whole life carbon performance, and whether public investment can protect communities from escalating climate risk. The Climate Change Committee’s warning that Heathrow’s third runway has “no credible pathway” within current climate policy unless aviation pays for genuinely cleaner flying signals a tougher consent environment for carbon-intensive projects.
For contractors, planners and financiers, whole life carbon assessment, embodied carbon evidence and robust lifecycle assessment are becoming central to project viability, not optional sustainability credentials. The decision strengthens scrutiny of the carbon footprint of construction across long-lived infrastructure, particularly where business cases rely on future decarbonisation rather than verified low carbon design today. It also raises the importance of life cycle cost, net zero carbon alignment and net zero whole life carbon claims in planning, procurement and investment decisions. Projects unable to demonstrate carbon footprint reduction, credible mitigation and environmental sustainability in construction will face greater policy, reputational and financial risk.
The Environment Agency’s appointment of GRAHAM to deliver the Oxford Flood Alleviation Scheme points to a more defensible direction for public infrastructure spending. Designed to protect properties along the Thames corridor and avoid more than £1.8bn in flood damage, the scheme frames green infrastructure as asset protection, climate resilience and sustainable urban development. It shows how sustainable building practices and low-impact construction can support public value when they reduce physical climate exposure and long-term economic losses.
The emerging priority is no longer green construction branding alone. Sustainable building design, sustainable design and eco-design for buildings must now be judged against whole life carbon, embodied carbon in materials, building lifecycle performance and resource efficiency in construction. The same pressure is driving demand for low carbon construction materials, low embodied carbon materials, renewable building materials, green building materials and transparent environmental product declarations (EPDs).
BREEAM, BREEAM v7 and similar frameworks are likely to gain significance as clients seek measurable evidence for net zero carbon buildings, energy-efficient buildings and low carbon building outcomes. Circular economy principles, circular economy in construction, circular construction strategies and end-of-life reuse in construction will become more important as the sector addresses the environmental impact of construction and accelerates decarbonising the built environment.
Sustainable construction is becoming a discipline of hard choices: what should be built, what must be defended, how climate resilience is funded, and whether optimistic emissions assumptions can survive regulatory scrutiny. Green concrete and carbon neutral construction may become increasingly credible through better sustainable material specification and green building products. Green airports remain a harder proposition under a planning system moving towards life cycle thinking in construction and evidence-led environmental accountability.
