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 this 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.
Sustainable construction is entering a results-driven phase defined by measurable performance rather than ambition. The UK’s £50 million investment in critical minerals strengthens the foundation for low carbon design and net zero carbon buildings, recognising that whole life carbon and embodied carbon in materials must be tracked from extraction to end-of-life reuse in construction. This alignment of industrial policy with environmental sustainability in construction reflects an emerging framework for whole life carbon assessment and lifecycle assessment within both infrastructure and residential building sectors.
Smart energy autonomy is accelerating the transition to energy-efficient buildings. Compact domestic battery systems and renewable energy integration demonstrate the expanding circular economy in construction, where resource efficiency and sustainable building practices are reshaping how homes are valued and retrofitted. Scotland’s rapid adoption of heat pumps and solar systems suggests growing confidence in sustainable building design, yet public perception of low carbon construction materials and life cycle cost remains a barrier to wider uptake.
AI-assisted planning systems within local authorities mark a critical step in digital transformation. By tackling administrative delays, these tools support sustainable urban development grounded in eco-design for buildings and verifiable environmental product declarations (EPDs). Parallel investment in green skills, including a £1 million apprenticeship initiative from Royal Mail, signals overdue recognition of the labour force’s role in achieving net zero whole life carbon performance.
The sector’s focus is shifting toward circular construction strategies, sustainable material specification, and quantifiable reductions in the carbon footprint of construction. Green construction now depends less on aspirational branding and more on comprehensive life cycle thinking in construction, where building lifecycle performance becomes the measure of success. With BREEAM and the upcoming BREEAM v7 reinforcing these standards, sustainable design is no longer optional but central to carbon neutral construction and genuine decarbonising of the built environment.
