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.
Construction’s shift to sustainability continues to draw attention as financing models increasingly support change across the supply chain. Lincoln CDM Services has adopted invoice finance to strengthen collaboration between contractors and suppliers, ensuring delivery of sustainable building practices. Stable funding is proving as critical as low carbon construction materials or energy-efficient buildings, safeguarding long-term adoption of sustainable building design.
Concerns over waste management are intensifying, with industry experts warning that construction and demolition waste could stall progress toward net zero Whole Life Carbon. The lack of clear policy and delayed investment is restricting recycling and reuse, undermining circular economy in construction efforts. Greater focus on end-of-life reuse in construction and resource efficiency in construction is now seen as essential to protect achievement of carbon footprint reduction goals.
Repurposing of outdated fossil fuel infrastructure in the US and Europe highlights potential pathways for the sector. Projects converting coal plants into data centre energy hubs illustrate how circular construction strategies can bring new value to redundant assets. This approach reduces embodied carbon in materials, cuts the carbon footprint of construction, and reinforces sustainable construction as a driver of wider decarbonising the built environment efforts.
Urban development continues to be shaped by transport planning, with the Energy Saving Trust publishing guidance for local authorities to advance low carbon design strategies. Sustainable urban development requires integration of mobility solutions with eco-design for buildings and green infrastructure. These measures influence building lifecycle performance and provide opportunities for net zero carbon buildings through coordinated planning.
Architectural projects are also driving awareness of environmental sustainability in construction. The planned Sustainability Hall in Taipei from architect Tadao Ando demonstrates how sustainable architecture can combine sustainable material specification with cultural value. It reinforces the role of sustainable building design in shaping public understanding of Whole Life Carbon Assessment and sustainable design.
Across these developments, industry leaders emphasise the need for lifecycle assessment and life cycle thinking in construction to ensure transparent benchmarks. From embodied carbon measurement to life cycle cost analysis, the sector is defining pathways toward carbon neutral construction. The alignment of finance, design innovation, and circular economy strategies is demonstrating that green construction and eco-friendly construction are becoming both achievable and commercially sustainable.
