In April 2017, the U.S. military dropped the most powerful conventional bomb ever used in combat here: the GBU-43/B Massive Ordnance Air Blast, known unofficially as the “mother of all bombs,” or MOAB. “All the people living in Asad Khel village became ill after that bomb was dropped,” says Wali, a 27-year-old farmer, pulling up the leg of his shalwar kameez to show the red bumps stretched across his calves. “I have it all over my body.” He says he got the skin disease from contamination left by the MOAB. “We would get 150 kilograms of wheat from my land before, but now we cannot get half of that,” he says. “We came back because our homes and livelihoods are here, but this land is not safe. The plants are sick, and so are we.” The bomb residue plaguing the village is but one example of the war’s toxic environmental legacy. For two decades, Afghans raised children, went to work and gave birth next to America’s vast military bases and burn pits, and the long-term effects of this exposure remain unclear. Dealing with the consequences of the contamination will take generations.

The strongest signal for sustainable construction is a shift from broad claims of sustainability towards measurable whole life carbon, circular economy delivery and climate resilience. In the UK schools estate, offsite construction is being positioned as a practical route to low carbon design, with standardised components, controlled factory production and buildings designed for disassembly reducing embodied carbon and supporting end-of-life reuse in construction. For public-sector clients under pressure to deliver quickly, whole life carbon assessment, lifecycle assessment and life cycle cost analysis are becoming central to procurement, sustainable building design and building lifecycle performance.

Circular economy in construction is gaining momentum through plans for a wind-turbine recycling facility in the Scottish Highlands. The project reflects a maturing renewable energy supply chain and a growing requirement to address the embodied carbon in materials after first use. Decommissioned blades and composite components could become feedstock for green building products, low carbon construction materials and future green infrastructure, cutting landfill dependence and improving resource efficiency in construction.

Materials research is also moving beyond waste management towards performance-led sustainable material specification. Work converting waste plastics, including packaging and consumer goods, into polymer networks capable of harvesting water from dry air suggests new possibilities for eco-design for buildings in hotter, water-stressed regions. If developed at scale, such innovation could contribute to low-impact construction, carbon footprint reduction and the wider use of green building materials with stronger environmental product declarations (EPDs).

The main constraint is delivery capacity. Labour shortages threaten construction programmes at the same time that net zero carbon buildings, net zero whole life carbon targets and BREEAM v7 requirements demand more precise design, assembly, refurbishment and materials recovery. Environmental sustainability in construction now depends on skills, data and accountability as much as ambition. Decarbonising the built environment will require clients, regulators and contractors to treat sustainable design, circular construction strategies and low embodied carbon materials as core requirements, not optional enhancements.
