Spending time outside during a heat wave can be sweaty, uncomfortable, even health-endangering, but scientists have come up with an innovation they say could provide relief: clothes that physically cool down the body. Researchers at the University of Massachusetts Amherst have developed a flexible, chalk-based coating which can be added to fabrics. During tests in scorching summer heat, they found it reduced the temperature underneath clothes by up to 8 degrees Fahrenheit compared to the air, and by up to 15 degrees compared to untreated fabrics. This innovation is one of a number of efforts to turn people's clothes into a tool against extreme heat, which is intensifying as humans continue to burn planet-heating fossil fuels. Heat is the deadliest type of extreme weather, causing heat exhaustion and even heat stroke, a potentially fatal illness where the body loses the ability to cool itself down. 📸 : Cherry Cai/RMIT University

Wildfires destroying homes in the Midlands and Shropshire crews moving between fire and flood show why sustainable construction must now treat climate resilience as a core design requirement. Sustainable building design, low carbon design and eco-design for buildings need to account for overheating, fire risk, drainage capacity, defensible space and durable fabric performance.

Whole life carbon, embodied carbon and life cycle cost are becoming inseparable from safety, insurability and asset value, making whole life carbon assessment and lifecycle assessment essential tools for developers, councils and investors.

Karachi’s mangrove loss reinforces the construction value of green infrastructure and nature-based flood protection. Tidal creeks, mangrove belts and resilient coastal landscapes can reduce erosion, store carbon and protect communities, supporting environmental sustainability in construction without relying solely on hard engineering. For sustainable urban development, green construction and eco-friendly construction must prioritise site planning, biodiversity and building lifecycle performance alongside energy-efficient buildings and net zero carbon buildings.

Plans for a wind-turbine recycling facility in the Scottish Highlands point to a more mature circular economy in construction. Renewable infrastructure must address end-of-life reuse in construction, resource efficiency in construction and the embodied carbon in materials, especially composite blades and complex low carbon construction materials. The shift supports circular construction strategies, low embodied carbon materials and net zero whole life carbon targets, aligning with BREEAM, BREEAM v7 and wider expectations for environmental product declarations (EPDs). The strongest signal for decarbonising the built environment is clear: sustainable building practices must measure the carbon footprint of construction across design, use, maintenance and decommissioning.
