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.

Technologically advanced materials are reshaping sustainable construction as carbon-sequestering innovations progress from concept to deployment. Heidelberg Materials’ integration of CarbonCure concrete technology demonstrates how captured CO₂ can enhance strength while reducing the embodied carbon of materials, directly addressing the carbon footprint of construction. This marks a decisive step toward net zero whole life carbon outcomes and aligns with the broader drive to decarbonise the built environment through low carbon construction materials.
The sector is also seeing renewed focus on renewable building materials such as engineered timber. Products promoted by manufacturers like West Fraser highlight timber’s dual capacity for carbon storage and cost efficiency, reinforcing its role in sustainable building design. Architects and developers are now applying lifecycle assessment and whole life carbon assessment principles to balance structural performance, life cycle cost, and the environmental sustainability in construction practices.
Policy and regulation are reinforcing these shifts. Insights from COP30 and the UK’s fiscal frameworks confirm that sustainable building practices, embodied carbon reduction, and energy-efficient buildings form the basis for measurable sustainability within green construction policy. BREEAM and upcoming BREEAM v7 standards are accelerating adoption of eco-design for buildings, ensuring that net zero carbon buildings move from aspiration to obligation across urban infrastructure.
Emerging sensing and data systems are redefining resource efficiency in construction. High-resolution soil analysis tools such as those within the Earth Rover programme exemplify circular construction strategies, improving site selection and supporting the circular economy in construction by optimising natural carbon sinks and reducing environmental impact of construction.
This collective momentum signals the next phase in low carbon design: an integrated approach where low embodied carbon materials, sustainable material specification, and building lifecycle performance guide strategic investment. Sustainable architecture and eco-friendly construction are no longer niche pursuits but core drivers of carbon neutral construction and long-term environmental sustainability.
