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.

A tightening regulatory and technical landscape is redefining sustainable construction across the UK and beyond. The Building Safety Act is reshaping project governance by requiring transparent reporting and accountability that link safety with environmental sustainability in construction. Compliance processes are driving a shift toward whole life carbon assessment, embedding sustainable building design principles at the earliest design stage and quantifying both operational and embodied carbon.
Digital systems such as the government’s waste‑tracking initiative are enabling circular economy in construction practices, mandating traceable material flows and revealing the carbon footprint of construction through verified lifecycle assessment. These data‑driven mechanisms enhance resource efficiency in construction and reinforce the wider transition to low embodied carbon materials and eco‑friendly construction.
Investment is converging on decarbonisation at scale. A new £120 million waste‑to‑hydrogen facility is designed to transform residual waste into clean fuel, supporting low carbon design and resilient net zero carbon buildings. Growth in grid‑balancing storage improves the stability of renewable‑powered operations, a prerequisite for energy‑efficient buildings and low carbon building performance across portfolios.
Governance frameworks are also advancing. The creation of a dedicated leadership structure for the Greenhouse Gas Protocol elevates global consistency in measuring whole life carbon and encourages transparent benchmarking using environmental product declarations (EPDs). This maturity strengthens sustainable building practices, fosters green construction aligned with BREEAM v7 standards, and supports decarbonising the built environment through life cycle cost and performance management.
The cumulative effect signals a transition to net zero whole life carbon imperatives governed by robust data, certified materials, and measurable outcomes. The progress may appear administrative, yet it represents the essential infrastructure of sustainable material specification, circular construction strategies, and long‑term green infrastructure supporting a truly carbon neutral construction sector.
