At the start of 2025, devastating wildfires tore through the Los Angeles region of California, causing hundreds of thousands of people to evacuate, creating an estimated $250 billion in damages, and directly claiming the lives of 31 people and contributing to the deaths of an estimated 440 people. Climate change made the hot, dry weather that intensified these fires 35% more likely—underscoring the need to act on the climate crisis before it puts more communities in harm’s way.
Tune back each day through the rest of the year to learn more about some of the most severe extreme weather events that shaped 2025. Heading into 2026, we deserve protections from climate change-fueled extreme weather events like the Eaton and Palisades fires. #2025inExtremeWeather
Severe Himalayan flooding exposed systemic infrastructure risk, cutting Nepal’s hydropower output by more than a tenth and confirming that resilience is fundamental to sustainable construction and environmental sustainability in construction.
Catchment-scale planning, diversified energy portfolios and redundancy in critical systems must sit alongside siting, access and social equity to keep projects viable. Policy momentum is shifting toward integrating adaptation into core planning, with procurement and finance required to price climate risk across whole asset lives through whole life carbon assessment, lifecycle assessment and life cycle cost analysis.
Targets for whole life carbon and embodied carbon should be locked into briefs and contracts, with BREEAM and BREEAM v7 used to embed building lifecycle performance, life cycle thinking in construction and sustainable building design.
Reconstruction that embraces green infrastructure, nature-based buffers and community-led recovery can avoid the “build–break–rebuild” loop. Circular economy in construction, circular construction strategies and end-of-life reuse in construction should guide material choices, supported by environmental product declarations (EPDs), sustainable material specification and low embodied carbon materials to cut the carbon footprint of construction. Eco-design for buildings, low carbon design and resource efficiency in construction are now baseline for energy-efficient buildings, green construction and eco-friendly construction.
US safety clearance for a mile‑deep nuclear reactor design signals decentralised, climate-resilient, low‑carbon power for energy‑intensive cement and steel, hardening supply for data‑rich construction workflows. Reliable clean baseload can accelerate decarbonising the built environment, enable net zero carbon buildings and net zero whole life carbon pathways, support carbon neutral construction and deliver measurable carbon footprint reduction with renewable building materials and green building materials in low carbon building programmes.
