Water is inherently short in supply in this arid nation. The difference is this crisis is hitting the capital, said Kaveh Madani, director of the United Nations University Institute for Water, Environment and Health. Tehran, home to around 10 million people, could run out of water altogether if consumption levels are not reduced, experts fear. The roots of the crisis lie in a tangle of factors including what engineers describe as decades of poor water management and an increasing imbalance between supply and demand. It's all compounded by climate change. Iran is experiencing one of its worst droughts on record, and its fifth consecutive year of drought. The country is also baking under brutal heat. Temperatures spiked above 122 degrees Fahrenheit in parts of the country this month, according to climatologist and weather historian Maximiliano Herrera. "Iran seems almost perennially in a record-heat status," he told CNN. Tap the link in bio for more. 📸 : Atta Kenare/AFP/Getty Images

The UK’s construction sector is entering a decisive phase in addressing environmental sustainability in construction as the Climate Change Committee warns that national infrastructure remains calibrated for outdated climate conditions. The call for large-scale retrofitting of homes and workplaces underscores the urgency of whole life carbon assessment and life cycle cost integration in both policy and practice. The proposed Energy Independence Bill aims to link renewable building materials and domestic energy generation with economic resilience, aligning sustainable building design more closely with national energy strategy.

Fiscal measures directed at construction and infrastructure are positioned to accelerate investment in low carbon construction materials and eco-friendly construction, supporting the shift toward net zero carbon buildings and whole life carbon management across the sector.

Artificial intelligence is emerging as a powerful driver of resource efficiency in construction, enabling comprehensive lifecycle assessment and real-time management of supply chains to lower the carbon footprint of construction. Its deployment has the potential to transform forecasting of embodied carbon in materials and enhance building lifecycle performance in line with circular economy principles. The growing use of data-led modelling marks a critical shift in sustainable design from conceptual ambition to measurable decarbonising the built environment outcomes.

Landscape-scale regeneration projects, such as woodland restoration in northern England, now integrate biodiversity and soil resilience into eco-design for buildings and land-use frameworks. This evolution in sustainable construction reflects the embedding of circular economy principles and end-of-life reuse in construction within long-term planning, distinguishing compliance-based action from aspirational rhetoric.

The convergence of digital innovation, legislative momentum, and robust sustainable building practices indicates that green construction is transitioning from choice to obligation, defining a new era in carbon neutral construction and net zero whole life carbon performance.
