The Global Status Report for Buildings and Construction (Buildings-GSR), a report 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. It also provides stakeholders with evidence to persuade policymakers and the overall buildings and construction community to take action. As outlined in the 2023 edition, the buildings and construction sector contributes significantly to global climate change, accounting for about 21 per cent of global greenhouse gas emissions. In 2022, buildings were responsible for 34 per cent global energy demand and 37 per cent of energy and process-related carbon dioxide (CO2) emissions. The 2022 update of the Global Buildings Climate Tracker (GBCT) paints a concerning picture: the gap between the current state and the desired decarbonisation path is significant. To align with the 2030 milestone, an annual increase of ten decarbonisation points is now required, a substantial jump from the six points anticipated per year starting in 2015. This year, the deep dive chapters are the following: Adaptation and resilient construction methods; Innovations in business cases as well as Nature-based solutions and biophilic design.
The UK’s latest review on greenhouse gas removals sets a defined trajectory toward net-zero carbon buildings by 2050, placing greater emphasis on a diversified approach that values both engineered technologies and nature-based solutions. This policy direction highlights the necessity of integrating whole life carbon assessments into every stage of sustainable building design. By examining embodied carbon in materials alongside operational emissions, the review promotes a shift toward net zero whole life carbon thinking. This reinforces the wider industry momentum towards decarbonising the built environment through robust measurement, transparent data and accountable policy guidance.
Within the construction and waste management sectors, new partnerships are driving environmental sustainability in construction practice. The collaboration between the Chartered Institution of Wastes Management and the Circular Economy Institute exemplifies how circular economy in construction principles are redefining project life cycles. These programmes champion eco-design for buildings, ensuring materials are specified for reuse and recycling at end-of-life. Such circular construction strategies are vital in reducing the carbon footprint of construction and strengthening the resilience of resource efficiency in construction workflows.
Digital transformation is accelerating the pace of greener practice. Site management platforms and data intelligence tools are enhancing building lifecycle performance by identifying inefficiencies that lead to material waste and unnecessary emissions. These advances align with broader sustainable design methodologies that combine lifecycle assessment and life cycle cost evaluation, ensuring that capital investment and long-term sustainability targets align. The integration of data-led systems supports sustainable building practices, low carbon design optimisation and transparent environmental product declarations (EPDs), helping firms meet stricter carbon reporting standards.
Industry leaders are calling for greater adoption of renewable building materials and low embodied carbon materials to close the gap between ambition and implementation. Research into low carbon construction materials is expanding, supporting eco-friendly construction models that meet BREEAM and BREEAM v7 benchmarks. Sustainable material specification now plays a decisive role in driving low-impact construction projects that advance green infrastructure and sustainable urban development. The growth of the circular economy provides opportunities for end-of-life reuse in construction, minimising waste and extending material lifespans through design foresight.
Momentum in sustainable construction remains strong, yet fragile. Ongoing challenges in policy clarity, financial investment and standardisation risk slowing progress. The industry’s success depends on embedding whole life carbon methodologies across the project chain—from initial concept to demolition and reconstruction. Achieving carbon neutral construction requires cohesive collaboration between architects, engineers, waste specialists and digital modellers grounded in life cycle thinking in construction. As global attention turns toward COP30, the built environment’s contribution to climate resilience will be measured not by rhetoric but by tangible reductions in the environmental impact of construction and sustained innovation across green building products, technologies and governance.
