The launch of the Global Circularity Protocol at COP30 has defined a pivotal shift in sustainable construction. Developed by the World Business Council for Sustainable Development and the One Planet Network, the framework introduces a measurable standard for circular economy in construction, giving companies a consistent method for assessing material reuse and lifecycle performance. This approach strengthens whole life carbon assessment by linking embodied carbon calculations with resource efficiency in construction and end-of-life reuse, instilling clear accountability for embodied carbon in materials across supply chains.

The UK’s planning approval for Cory’s Riverside waste-to-energy facility with integrated carbon capture and storage highlights the transition towards low carbon construction materials and carbon neutral infrastructure. By combining energy recovery and carbon capture, the project contributes directly to reducing the carbon footprint of construction and aligns with net zero carbon and whole life carbon targets. It reflects the broader aim of achieving net zero whole life carbon through low carbon design tied to measurable life cycle cost and lifecycle assessment outcomes.

Digital systems are also reshaping environmental sustainability in construction. The Green Digital Action Hub, initiated at COP30, focuses on lowering the energy demand of smart city technologies and data-driven sustainable building design. As artificial intelligence and the Internet of Things are embedded into green construction and sustainable architecture, future BREEAM and BREEAM v7 benchmarks may place greater emphasis on eco-design for buildings, sustainable material specification, and carbon footprint reduction through efficient computational modelling.

Growing unease over carbon markets underscores the importance of transparent lifecycle assessment within sustainable building practices. The shift from offset-based carbon accounting to verifiable decarbonising the built environment signals the maturity of sustainable design, where carbon neutrality depends on traceability and disclosure through environmental product declarations (EPDs).

These developments indicate a fundamental progression from aspirational rhetoric to enforceable standards. Sustainable building design and low carbon building strategies are coalescing with circular construction strategies to redefine environmental impact of construction. The industry’s readiness to adopt robust frameworks for eco-friendly construction, green building materials, and renewable building materials will determine the credibility of future sustainable urban development worldwide.
