They were once a refuge from the chaos above, but now our subways are more hazard than haven: The infrastructure that powered the last century of urban life was not built for the one we're in.
In 2012, Superstorm Sandy inundated the oldest and lowest stations in Manhattan and inspired innovations like an inflatable plug big enough to seal off an entire tunnel and keep floodwater corked and contained. But these systems require setup time, which is possible before a hurricane surge, but worthless during rain bombs that can turn streets into rivers in minutes.
While parts of London's Tube have flooded several times in the past few years, scorching summers create a fresh hell, enhanced by the heat-trapping clay geology. Only 40% of the London Underground system is air conditioned, mostly on lines closer to the surface and those that run above ground. New trains on the Piccadilly line will soon come with relief, but some may never have it.

Policymakers and industry leaders continue to accelerate the shift toward sustainable construction, setting new benchmarks for environmental sustainability in construction and deepening commitments to decarbonising the built environment. The UK’s Department for Environment, Food and Rural Affairs has given the Environment Agency expanded authority to streamline project permitting, aiming to embed life cycle thinking in construction more efficiently into planning and reduce administrative bottlenecks. The reforms are intended to cut red tape for low-risk activities while still supporting resource efficiency in construction, although environmental advocates remain cautious about risks of diminished oversight.
Materials innovation is taking centre stage in the global effort to reduce the carbon footprint of construction. Kingspan’s new green steel partnership across the Asia-Pacific region marks a strategic advance in addressing embodied carbon in materials. By shifting to low-carbon steel options, the company strengthens its alignment with whole life carbon assessment principles and contributes to the creation of low embodied carbon materials. Such initiatives reduce both the embodied and operational carbon of structures, highlighting a practical application of eco-design for buildings and signalling tangible progress toward net zero whole life carbon targets.
Holcim is expanding the boundaries of sustainable building practices by introducing electric mobility across its logistics network and prioritising sustainable material specification. The company’s broader sustainability roadmap integrates circular construction strategies and aims to drive progress towards carbon neutral construction. The transition to electric fleets, coupled with responsible sourcing and life cycle cost evaluations, exemplifies a systemic approach to reducing emissions throughout the building lifecycle performance, rather than focusing on individual project achievements alone.
An increasing emphasis on green skills and education underscores that sustainable urban development depends as much on people as on technology. National Grid’s outreach programmes have introduced nearly 150,000 students to the principles of sustainable building design and low carbon construction materials, helping to build capacity for the next generation of engineers, architects, and environmental specialists. This investment in long-term knowledge ensures that lifecycle assessment and whole life carbon methodologies become integral to professional practice rather than theoretical aspirations.
Stonewater’s completion of its 8,000th energy-efficient home since 2015 demonstrates the scalability of eco-friendly construction and affordability in sustainable housing. The project integrates green building materials, renewable building materials, and design standards consistent with BREEAM and BREEAM v7 assessments. The housing association’s achievement reflects the growing capability to combine low carbon design, sustainable architecture, and circular economy in construction principles within social housing models, advancing the UK’s ambition for net zero carbon buildings.
These developments collectively point to a maturing construction ecosystem grounded in measurable outcomes and transparent reporting through environmental product declarations (EPDs). Whether through green construction innovation, end-of-life reuse in construction, or continuous carbon footprint reduction, the sector is aligning itself toward a future where whole life carbon accountability and sustainable design steer every stage of the built environment’s evolution.
