One of Heather Welch's jobs — before she was fired via an email giving her just 90 minutes to pack up and leave — was to prevent collisions between the ships and whales navigating the water along the US West Coast. Welch, who was an ecologist at the National Oceanic and Atmospheric Administration for nearly a decade, specialized in mapping the movement of marine animals. This information helped ships map their routes, and fisheries improve their catch, while avoiding accidentally scooping up and killing sea lions or turtles. Welch is just one of more than 1,000 people who in the past few weeks have been laid off from NOAA, the nation's top weather and climate agency. It was already understaffed before President Donald Trump's cuts, and there are more to come. NOAA's remit is wide, but one of its most critical roles is to observe the oceans. Multiple scientists told CNN the layoffs are taking expert eyes off the oceans at the worst possible time: as the oceans undergo extreme change — some of which remains largely unexplained — with deep impacts for humans, wildlife and economies.

Great Britain’s renewable energy system advanced as its wind generation reached a record 23,825 MW, strengthening the pathway towards net zero carbon buildings and a resilient green infrastructure. Government measures to fortify subsea cables confirm a commitment to decarbonising the built environment and ensuring the security of renewable supply linked to sustainable construction. The appointment of a new leader at Great British Energy highlights strategic capacity expansion for low carbon design and a more sustainable energy mix supporting whole life carbon reduction across the building sector.

Material supply chains showed renewed complexity as Europe delayed enforcement of deforestation rules, affecting traceable sourcing of mass-timber and the embodied carbon in materials that underpin sustainable building practices. The deferral reinforces the need for lifecycle assessment and end-of-life reuse in construction, ensuring renewable building materials meet the standards of environmental product declarations (EPDs). Clients now prioritise deforestation-free, rights-respecting, low embodied carbon materials supported by circular economy in construction frameworks and robust whole life carbon assessments.

Rising energy prices across North America increase attention on energy-efficient buildings, deep retrofit strategies and life cycle cost optimisation. Developers are integrating eco-design for buildings that enhance operational performance while lowering the carbon footprint of construction. Water resilience is shaping sustainable building design in the UK, with drought prediction and reuse systems becoming part of life cycle thinking in construction and sustainable urban development.

The transition demands resource efficiency in construction and carbon neutral construction models that directly address the environmental impact of construction. Developers and contractors must commit to building lifecycle performance monitoring, circular construction strategies and sustainable material specification aligned with BREEAM v7 and similar frameworks. Environmental sustainability in construction now depends on design teams treating embodied carbon and whole life carbon as defining metrics for low-impact construction and durable, eco-friendly assets.
