Global Status Report for Buildings and Construction

United Nations 2 years ago

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.

Water scarcity has become a core concern for sustainable construction and sustainable building design, with the United Nations warning of potential global water bankruptcy and heightened risk to desalination plants in the Gulf. The construction sector is shifting towards diversified water systems that embed efficiency, reuse, and resilience. These changes align with whole life carbon and lifecycle assessment principles, ensuring environmental sustainability in construction through resource efficiency in construction and life cycle cost analysis. In the UK, stronger regulation following pollution incidents is driving utilities to invest in cleaner networks and green infrastructure, creating new pipelines of low carbon construction materials and sustainable building practices.

Digital manufacturing is transforming eco-friendly construction through AI-driven tools that automate complex formwork and optimise material use. By integrating eco-design for buildings and low carbon design methodologies, contractors reduce embodied carbon in materials and the overall carbon footprint of construction. This digital precision supports net zero whole life carbon strategies and demonstrates how circular construction strategies underpin a circular economy in construction.

Energy security and climate risk are reinforcing the need for carbon neutral construction and renewable building materials. Projects optimised for energy-efficient buildings and net zero carbon buildings are proving more resilient, cost-stable, and aligned with whole life carbon assessment frameworks. The industry trajectory favours sustainable material specification, end-of-life reuse in construction, and decarbonising the built environment through lifecycle performance and life cycle thinking in construction. Firms advancing sustainable design founded on building lifecycle performance and resource efficiency will lower embodied carbon while improving long-term asset resilience, delivering measurable reductions in the environmental impact of construction.
