URGENT action is needed to remove PFAS chemicals from the environment, experts have said, after a UK government agency found there was not yet enough evidence to directly link industrial PFAS exposure to health impacts.
Climate policy, materials science and building performance are converging around a tougher definition of sustainable construction: assets must cut embodied carbon, reduce operational demand, protect occupant health and remain resilient under climate stress. The £23.7m North East innovation programme for clean chemicals and low carbon construction materials signals a shift from isolated green construction pilots to regional supply chains capable of delivering binders, coatings, insulation and components at scale. For developers and contractors, sustainable material specification, environmental product declarations (EPDs) and whole life carbon assessment are becoming central to procurement, not optional evidence for certification.
The focus is moving beyond carbon targets alone. Evidence from more than 4,500 damp and mould-affected buildings shows that energy-efficient buildings can fail when retrofit treats airtightness as a single measure rather than part of sustainable building design. Poor ventilation, weak moisture control and inadequate maintenance undermine building lifecycle performance, creating health risks, compliance exposure and higher life cycle cost. Low carbon design must therefore align with indoor environmental quality, lifecycle assessment and life cycle thinking in construction.
Water scarcity is now a core test of environmental sustainability in construction. Persistently low reservoir levels in England reinforce the case for rainwater harvesting, greywater reuse, permeable surfaces, drought-tolerant landscaping and tighter site water management. These sustainable building practices support green infrastructure, resource efficiency in construction and climate-ready development, especially as flood risk and water stress reshape planning expectations.
Completion of HS2’s Westbury Viaduct across the Great Ouse floodplain highlights the scrutiny facing major infrastructure: the carbon footprint of construction, ecological protection, value for money and long-term resilience must be assessed together. The sector’s direction is clear. Net zero carbon buildings, net zero whole life carbon strategies, circular economy in construction, end-of-life reuse in construction and low embodied carbon materials are defining credible progress. Standards such as BREEAM and BREEAM v7 will increasingly be judged by whether they drive measurable carbon footprint reduction, circular construction strategies and durable low carbon building outcomes, rather than polished claims of eco-friendly construction.
