A landmark investigation into the spread of synthetic particles has identified a serious threat to the flora across the world.
Published in the journal Proceedings of the National Academy of Sciences USA, researchers believe they now have proof that microplastics - fragments of less than 5mm in
The UK government’s £90m backing for heat networks in London, Bradford and Solihull, alongside upgrades to 76 existing networks, marks a significant shift for sustainable construction. The proposed River Thames “mega heat project” could help unlock up to £5bn of investment by capturing low-carbon heat at urban scale, strengthening the infrastructure needed for net zero carbon buildings and wider decarbonising the built environment.
For developers, contractors and local authorities, the move raises the importance of whole life carbon, whole life carbon assessment and life cycle cost in project planning. Low carbon design can no longer be judged only by fabric, systems and embodied carbon in materials within the plot boundary. Building lifecycle performance will increasingly depend on access to shared green infrastructure capable of reducing operational emissions across dense urban areas.
Heat networks support sustainable urban development where density, public procurement and long-term ownership align. They also reinforce life cycle thinking in construction, linking sustainable building design, energy-efficient buildings and carbon footprint reduction with district-scale investment. Credible delivery will depend on consumer protection, planning coordination, connection certainty and robust demand aggregation.
The policy direction strengthens the case for net zero whole life carbon strategies, BREEAM and BREEAM v7-aligned decision-making, sustainable material specification, environmental product declarations (EPDs), low embodied carbon materials and circular construction strategies. Green heat is moving from a niche feature to civic infrastructure, making environmental sustainability in construction a shared responsibility between asset owners, designers, contractors and public authorities.
