Sometime between today and 200 years from now, scientists say “the big one” will hit the United States. There is danger lurking on the sea floor off the Pacific Northwest’s coast: After centuries of two tectonic plates pushing up against each other, the Cascadia subduction zone that runs from Northern California all the way up to British Columbia is due to rupture — possibly in our lifetimes. The resulting earthquake could be a devastating magnitude 9.0, and the subsequent tsunami could be 100 feet high, overwhelming coastal cities and towns. Around 13,800 people could die and more than 100,000 others could be injured, the Federal Emergency Management Agency has estimated. In short, it could be the worst natural disaster the United States has seen in modern times. And many scientists say we are less prepared for it than ever before. The league of experts and scientists who have spent decades keeping watch — the guardians at the gate — is being decimated by the Trump administration’s staffing cuts. It’s not just earthquakes and tsunamis; experts who sound the alarm for volcano eruptions say the cuts will be felt most when there’s a crisis. The scientists who watch the sun for invisible-yet-crippling solar storms are not just losing staff; they face being moved into an entirely different agency.

Momentum in sustainable construction is now driven by tangible progress in materials and methods rather than declarations. The focus on reducing embodied carbon in materials and undertaking robust whole life carbon assessment is reshaping how developers, architects and engineers define sustainable building design. Initiatives such as the Reducing Plastics in Construction Summit reinforce the value of renewable building materials, eco-design for buildings and circular economy in construction frameworks to eliminate petroleum-based polymers and improve resource efficiency in construction.

Biobased composites, recyclable resins and modular approaches are being evaluated through lifecycle assessment tools that can accurately measure the carbon footprint of construction and inform sustainable material specification throughout each project stage. Digitisation is rapidly becoming integral to low carbon design and energy-efficient buildings. Advanced platforms now enable unified modelling of cost, performance and carbon, aligning lifecycle cost optimisation with environmental sustainability in construction.

TM2 Bygg’s software-led method illustrates how low carbon building processes built on data-driven insights help achieve net zero carbon buildings and deliver improved building lifecycle performance. At the policy level, regulators are reinforcing requirements for measurable reductions in embodied carbon and clear evidence of net zero whole life carbon outcomes. These shifts point toward an industry-wide transformation grounded in whole life carbon transparency and the adoption of BREEAM v7 and other sustainable building practices to standardise reporting.

The result is a market that values circular construction strategies, end-of-life reuse in construction and environmental product declarations (EPDs) as verification of a project’s environmental impact of construction. New renewable energy infrastructure, including next‑generation geothermal systems, could redefine the carbon footprint reduction potential of green building materials and low carbon construction materials. As baseload renewables expand, achieving carbon neutral construction and sustainable urban development becomes increasingly viable. The sector is moving beyond pilot projects toward a mature phase of green construction, integrating life cycle thinking in construction and decarbonising the built environment as core business practice.
