The climate activist group Extinction Rebellion claimed responsibility for scaling Venice's Rialto Bridge and dumping the chemical dye fluorescein into the canal, turning it fluorescent green under a sign that read: "While the government speaks, we hang by a thread."
"We know that our future is in danger, and that nothing is being done to protect it," the group wrote in a Facebook post accompanied by images, explaining that the protest was specifically against the COP28 climate summit, currently held in Dubai. "It was chaired by the CEO of an oil company and took place under the siege of the 2,400 fossil fuel lobbyists invited to participate," the group said.
Venice mayor Luigi Brugnaro tweeted that public services, including transportation, were halted due to the protest.
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.
