Remember that heatwave three summers ago in Portland that melted metal and broke asphalt? Multonah County is suing fossil fuel companies for causing a public health crisis. The county’s lawsuit says that they will ultimately incur costs in excess of $1.5 billion to deal with the effects of the 2021 heat dome caused by climate change — driven by the emissions from large fossil fuel companies. “When it comes to the extreme heat events that affected Portland, the scientists concluded, in looking at that event and then looking at historical records of heat waves in the Pacific Northwest, it would not have happened, but for human-caused climate change.” — Pat Parenteau, Professor of Law Emeritus at Vermont Law and Graduate School Source: “‘Not Caused by an Act of God’: In a Rare Court Action, an Oregon County Seeks to Hold Fossil Fuel Companies Accountable for Extreme Temperatures” by Victoria St. Martin for Inside Climate News “What Is a Heat Dome?” by William Gallus &The Conversation US via Scientific American Design by @moniquezarbaf for @futureearth

AI-driven innovation is reshaping sustainable construction, as demonstrated by Greyparrot’s Analyser being named on TIME’s Best Inventions of 2025 list. The technology’s precision in identifying recyclable materials reinforces circular economy in construction principles and strengthens whole life carbon assessment practices by improving data capture on waste flows. This form of circular construction strategy supports resource efficiency in construction and encourages greater adoption of eco-design for buildings, reducing the embodied carbon in materials and promoting a measurable approach to the carbon footprint of construction. By integrating artificial intelligence into sorting systems, the industry is taking a critical step toward decarbonising the built environment through technology-led environmental sustainability in construction.

Recognising that machinery alone cannot achieve sustainability goals, the UK construction sector is prioritising human capital to meet the demands of net zero whole life carbon objectives. A coordinated drive to develop new green skills underscores the importance of life cycle thinking in construction and low carbon design expertise. Building professionals are being urged to strengthen their competence in sustainable building practices and whole life carbon management, ensuring future workforce capability in sustainable building design and renewable building materials. These efforts are vital for maintaining BREEAM and BREEAM v7 certification standards which continue to define quality benchmarks for low carbon building performance.

The European Union’s compromise on its Corporate Sustainability Reporting Directive (CSRD) and Corporate Sustainability Due Diligence Directive (CSDDD) is poised to reshape how construction firms disclose their environmental impacts. By applying due diligence primarily to large corporations, the policy risks excluding smaller firms from conducting full whole life carbon and lifecycle assessment reporting. Such omissions could distort visibility into total embodied carbon across supply chains, reducing transparency in life cycle cost evaluation. Broader inclusion would help achieve carbon footprint reduction across all tiers of the built environment and encourage greater adoption of sustainable material specification consistent with the circular economy.

Global scrutiny of sustainable architecture and construction is intensifying in the run-up to COP30, drawing political figures and sustainability advocates alike. Prince William’s planned attendance symbolises renewed commitment to net zero carbon buildings and carbon neutral construction policy, setting a high bar for environmental sustainability in construction targets. These global gatherings amplify pressure to deliver energy-efficient buildings and low carbon construction materials backed by environmental product declarations (EPDs). Governments and construction enterprises alike are expected to demonstrate measurable reductions in the carbon footprint of construction aligned with whole life carbon and embodied carbon standards.

Regulators in Wales have reinforced the importance of compliance as a foundation for sustainable construction. A significant fine imposed on a waste operator underscores how enforcement directly supports cleaner practices and enhances building lifecycle performance. Tackling illegal dumping not only prevents environmental degradation but also sustains the circular economy by protecting legitimate recycling pathways crucial for low-impact construction. Integrity in waste management underpins the success of sustainable design and ensures that resource efficiency in construction continues to strengthen green infrastructure. The ongoing shift toward environmentally responsible building demonstrates how strong governance, technical innovation, and skilled workforces can combine to reduce embodied carbon and ensure sustainability remains at the core of the construction industry.
