Most architects look to control nature; Kongjian Yu wants it to take over. Intense storms are on the rise and cities across the world are finding it difficult to cope with deluges of floodwater. But instead of using high-tech, concrete-based engineering solutions to defend against the vagaries of the climate crisis, the Chinese landscape architect and urban planner lets nature do the work. For over a decade, Yu and his firm Turenscape have designed nature-based "sponge cities" intended to soak up and retain stormwater before releasing it back into the environment. Varied in form and scale, the projects create new parks, restore wetlands and install rain gardens and permeable pavements, among much else.

The UK construction sector is entering a decisive phase of sustainable construction focused on measurable carbon reduction rather than symbolic gestures. The launch of the UK’s first commercial‑scale carbon capture and storage facilities in the East Coast Cluster, operated by pX Group, marks significant progress in decarbonising the built environment. These links between energy‑intensive industries and new CO₂ transport and storage systems are reshaping the embodied carbon profile of essential materials such as cement and steel, critical to sustainable building design and eco‑friendly construction. The integration of low embodied carbon materials forms a foundation for the adoption of whole life carbon assessment methods and lifecycle assessment strategies now demanded across the supply chain.

Concrete innovation is accelerating as “green concrete” becomes a viable element of low carbon design. Manufacturers are scaling from trials to full delivery. JCB’s move to provide a 100% biodiesel option for tracked excavators demonstrates practical progress toward net zero carbon buildings and carbon neutral construction. Effective reductions depend on verified renewable building materials and traceable biofuels, requiring stricter sustainable material specification and transparent environmental product declarations (EPDs). Verified sourcing and supply are vital to minimising the carbon footprint of construction and improving resource efficiency in construction.

Across projects, whole life carbon thinking is now inseparable from life cycle cost analysis. Intensifying climate conditions—from escalating floods to drought stress—demand resilient, energy‑efficient buildings and green infrastructure designed using eco‑design for buildings principles. Resilience and sustainability are no longer optional performance indicators but integral to building lifecycle performance and sustainable building practices. The industry response is to secure supply from emerging low carbon construction materials clusters, adopt verified fuels and plant emissions data, and embed circular construction strategies.

The momentum reflects a commitment to environmental sustainability in construction, combining circular economy in construction models with frameworks such as BREEAM V7 to achieve net zero whole life carbon outcomes. Through transparent lifecycle assessment and life cycle thinking in construction, every project can demonstrate measurable progress in carbon footprint reduction and deliver the economic and environmental returns driving the transition to sustainable urban development.
