Bulacan Province, Philippines The Philippine capital, Manila, and Manila Bay, are part of one of the most vulnerable metropolitan areas in the world due to climate change-driven sea rise. Less than 15 km (10 miles) north of Manila, coastal communities are sinking faster than the climate crisis is raising sea levels. "What is being projected 50 years from now or 100 years from now for many parts of the globe", Fernando P. Sirinagan, director of the University of the Philippines Marine Science Institute told Reuters, " is actually happening right now at even faster rates", in low-lying areas in Bulacan Province. Due to climate change, the UN estimates the global average sea level rise of 3 mm (0.11 inches) every year compounds the effect of land subsiding, in a region that is hit by, on average, 20 typhoons annually. That makes flooding at high tide a daily occurrence while rendering it extremely vulnerable to storm surges. . #climatecrisis #globalwarming #climatechange #searise #manilabay #philippines #water #coastalsearise #jameswhitlowdelano

Sustainable construction is moving from exemplar projects to market-wide system design, with clean steel emerging as a critical test for whole life carbon policy. A new study suggests the global shift to low-carbon steel could be achieved without raising consumer costs through a revenue-neutral policy model, strengthening the case for low embodied carbon materials in mainstream procurement.

For contractors, developers and public clients, the issue is no longer whether green building materials can perform, but how governments can de-risk low carbon construction materials, reduce the carbon footprint of construction and support net zero whole life carbon targets without shielding high-emission incumbents.

The UK retrofit agenda is becoming central to environmental sustainability in construction. The National Retrofit Hub’s call for a stronger framework comes as electricity and gas prices begin to decouple, improving the life cycle cost case for heat pumps, energy-efficient buildings and electrified homes.

Retrofit policy now needs consistent standards, skilled delivery capacity and consumer protection, backed by whole life carbon assessment, lifecycle assessment and better evidence on building lifecycle performance. Public support for requiring data centres to share waste heat with nearby homes signals a shift in sustainable urban development, treating rejected heat as green infrastructure rather than waste.

Climate adaptation is also reshaping sustainable building practices. GRAHAM’s appointment to deliver the Oxford Flood Alleviation Scheme highlights rising investment in resilience, while reports of roads melting in eastern England expose the environmental impact of construction decisions based on historic weather assumptions.

The built environment is being asked to cut embodied carbon in materials while improving durability against heat, flooding and infrastructure stress. The strongest response will combine sustainable building design, low carbon design, circular economy in construction, sustainable material specification, environmental product declarations (EPDs) and end-of-life reuse in construction. BREEAM, BREEAM v7 and other performance frameworks are likely to play a growing role as clients demand net zero carbon buildings, resource efficiency in construction and credible carbon footprint reduction across the full asset lifecycle.
