🄵 Sweltering nights are over 20x more frequent in Paris today than they were the last time Paris hosted the Olympics, 100 years ago. What are the risks of extreme and humid heat? šŸ’§ When relative humidity is over 60%, sweat evaporates more slowly, which makes it harder for the body to cool down quickly enough to prevent overheating. ā˜€ļø Exposure to extreme heat can lead to heat-related illness —causing heat cramps, heat exhaustion, and in some cases fatal heat stroke. If we want to keep the tradition of summer and winter Olympics games alive for future generations we need to hold polluters accountable for their emissions now.

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.
