Halfway up the coast of Western Australia, American tourists Emily Wapman and Evan Risucci are riding a gentle current off Turquoise Bay, one of the country’s most remote and beautiful beaches. It’s called drift snorkeling, and the water’s guiding them over Ningaloo, one of the world’s longest near-shore reefs, revealing coral that’s as white as the sand on the sea floor — drained of color by the stress of a severe and prolonged marine heatwave. The Californians met in December on a dating app and are now touring Australia in an aging four-wheel drive they bought online and equipped for adventure. Risucci, a filmmaker, admits he knows little about coral but is learning a lot from his travel companion. “I thought that the white coral was the live coral,” he said, squinting in the harsh Australian sun. “It’d be good for tourists to know what’s actually happening,” he said. “Someone from the United States might come here and think, ‘wow, this is so pretty,’ and be completely oblivious to the fact that it’s all dead.” It’s not all dead, molecular ecologist Kate Quigley told CNN from a boat bobbing above Tantabiddi Sanctuary Zone, a popular destination for local tour boats within Ningaloo Marine Park off the West Australian coast. Ningaloo Reef is sick, like many coral reefs around the world. Read more at the link in @cnnclimate’s bio. #calltoearth 📸: Nush Freedman for CNN

The UK’s acceleration toward *sustainable construction* underscores a decisive shift from ambition to delivery. National Grid ESO’s reforms to the grid connection process remove zombie projects and prioritise actionable, low carbon design ready to unlock billions in clean energy infrastructure. This structural change supports *green infrastructure* essential to *decarbonising the built environment*, linking energy planning with *sustainable building practices* that address both whole life carbon and embodied carbon impacts through rigorous whole life carbon assessment.

Offshore wind’s expansion, now generating nearly one-fifth of Britain’s electricity, highlights how *environmental sustainability in construction* relies on scalable, *eco-friendly construction* solutions. The developing offshore supply chain demands *sustainable building design* that integrates *circular economy in construction* strategies and *resource efficiency in construction*, enabling the transition towards *net zero carbon buildings* and *net zero whole life carbon* performance.

While material innovation remains subdued, the rise of energy-efficiency retrofits reflects a shift towards life cycle cost optimisation and *building lifecycle performance* over short-term gain. Firms such as Mapei point to recovery driven by energy-efficient buildings and *low embodied carbon materials*, reinforcing the value of *eco-design for buildings* and *sustainable material specification* guided by *environmental product declarations (EPDs)*. These principles strengthen the circular economy ethos and advance *carbon footprint reduction* across every project stage, from design to *end-of-life reuse in construction*.

Africa’s emerging solar market signals global diversification of *green construction*, with the continent expected to become a testbed for *low carbon building* strategies suited to extreme climates. The transition invites adoption of *circular construction strategies*, *renewable building materials*, and *sustainable urban development* underpinned by *life cycle thinking in construction*.

The alignment of policy reform, financial investment, and technical capability confirms that *sustainable design* has become core to delivering *carbon neutral construction* and reducing the *carbon footprint of construction* worldwide. The era of incremental action is ending—the new metric of success is measurable whole life carbon performance and resilient, *green building materials* innovation delivering true *sustainability* in the built environment.
