California’s mountain towns and ski resorts are digging out after a blockbuster blizzard buried them and major roads under several feet of snow. The storm slammed California’s mountains for multiple days before wrapping up Monday. The most extreme conditions targeted the highest elevations of the Sierra Nevada, where over 10 feet of snow and hurricane-force wind gusts of 170 mph-plus were reported. Additional snow will fall across high elevations of Northern California and the Pacific Northwest into Wednesday, as a new storm pushes into the region but amounts are expected to be well short of the weekend’s monster storm. But, the weather system led to a positive development — the state’s snowpack, a critical source of water for California in the warmer months. Statewide snow water equivalent — a measure of how much water is contained within snow — has risen above average for the first time this winter, overcoming a significant deficit from earlier in the season, according to data from the California Department of Water Resources.

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.
