It's more than 100 feet long, at least 300 years old and visible from space. The world's largest coral has just been discovered in the southwest Pacific Ocean, scientists announced. It's three times larger than the previous record-breaker in American Samoa, according to Pristine Seas, and longer than a blue whale, the planet's biggest animal. "Just when we think there is nothing left to discover on planet Earth, we find a massive coral made of nearly 1 billion little polyps, pulsing with life," said Enric Sala, National Geographic explorer in residence and founder of Pristine Seas. Corals are vital for the marine creatures that rely on them for food and shelter, but also for humans. They are an indirect food source for an estimated 1 billion people, by helping support fisheries, and provide a buffer against storms and sea level rise. For the scientists, it's a career highlight. "Making a discovery of this significance is the ultimate dream," said Paul Rose, a National Geographic Pristine Seas expedition leader. 🎥 : National Geographic Pristine Seas

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.
