The world has entered "an era of global water bankruptcy" with irreversible consequences, according to a new United Nations report.
Regions across the world are afflicted by severe water problems: Kabul may be on course to be the first modern city to run out of water. Mexico City is sinking at a rate of around 20 inches a year as the vast aquifer beneath its streets is over-pumped. In the US Southwest, states are locked in a continual battle over how to share the shrinking water of the drought-stricken Colorado River.
"If you keep calling this situation a crisis, you're implying that it's temporary. It's a shock. We can mitigate it," said Kaveh Madani, director of the UN University's Institute for Water, Environment and Health, and the report's author.
With bankruptcy, while it's still vital to fix and mitigate where possible, "you also need to adapt to a new reality… to new conditions that are more restrictive than before," he told CNN.
The statistics in the report are stark: more than 50% of the planet's large lakes have lost water since 1990, 70% of major aquifers are in long-term decline, an area of wetlands almost the size of the European Union has been erased over the past 50 years, and glaciers have shrunk 30% since 1970. Even in places where water systems are less strained, pollution is reducing the amount available for drinking.
"Many regions are living beyond their hydrological means" and it's impossible now to return to conditions that used to exist, Madani said.
It brings human consequences: nearly 4 billion people face water scarcity for at least one month every year.

Flood-performance certificates planned for government and Flood Re testing before a wider 2027 rollout signal a major shift for sustainable construction: climate resilience is becoming a measurable asset risk. Flood exposure, insurance access and property value are moving into the same decision framework as whole life carbon, life cycle cost and building lifecycle performance. A new national flood-advice service and protection pledge for 200,000 properties strengthen the case for sustainable building design that treats adaptation, green infrastructure and low-impact construction as core requirements rather than optional upgrades.
Bupa’s expanded work with the Norman Foster Foundation on urban greening, active travel and public cooling reinforces the link between healthy places and environmental sustainability in construction. The direction supports sustainable urban development, eco-design for buildings and sustainable architecture that reduces overheating, improves walkability and makes neighbourhoods more resilient. For developers pursuing BREEAM, BREEAM v7, net zero carbon buildings and net zero whole life carbon, the message is clear: sustainable design must account for public health, heat risk, flood resilience and operational energy use across the full building lifecycle.
Reports that the UK and EU are moving closer to linking emissions trading systems could reshape procurement for steel, cement and other high-emission products. A deeper carbon market would increase pressure to cut the carbon footprint of construction through low carbon design, low carbon construction materials, green building materials, renewable building materials and stronger sustainable material specification. Credible carbon pricing would make embodied carbon, embodied carbon in materials and environmental product declarations (EPDs) more influential in tendering, lifecycle assessment and whole life carbon assessment.
New research suggesting insulation schemes may be underestimating heat loss exposes a persistent performance gap in energy-efficient buildings. Models are not enough if completed assets fail in use. As electrification and battery storage accelerate, demand reduction becomes central to net zero carbon, carbon footprint reduction and decarbonising the built environment. The sector needs sustainable building practices based on measurement, resource efficiency in construction, circular economy principles, circular economy in construction, end-of-life reuse in construction and circular construction strategies. Low carbon building delivery, eco-friendly construction and carbon neutral construction now depend on verified outcomes, not design intent alone.
