There were 90 declarations of "major disasters" in 2024. It was one of the worst years for disasters declarations in the last three decades (1995-2024), according to a new analysis from the International Institute for Environment and Development, or IIED, shared exclusively with CNN. Ninety major disaster declarations in a year is nearly double the annual average of 55 declarations, according to the London-based think tank. It translates to a major disaster declaration every four days. Researchers also found that 41% of the US population lived in a county where a major disaster or emergency was declared — about 137 million people. "Our analysis of FEMA data shows the agency has been responding to a growing number of climate-driven disasters over the past few decades. This is in line with what scientists warned us would happen," said Sejal Patel, senior climate finance researcher at IIED, in a statement to CNN. It comes as the Trump administration plans for deep staff cuts at FEMA. "As global temperatures continue to rise, all levels of government will have no choice but to help people adapt to the realities of climate change," Patel said, adding political leaders should be focusing on how to adapt and build resilience against climate change threats, including solutions like stronger building codes, early warning systems, reenvisioning the homeowners insurance industry and infrastructure like flood barriers.

Climate damage and material waste are reshaping sustainable construction more forcefully than certification culture. The loss of 38 homes to wildfire in the Midlands has exposed the need for sustainable building design that treats fire resilience, flood resistance and passive survivability as core requirements. Shropshire fire crews’ warnings over escalating wildfire and flooding extremes underline a decisive shift for green construction: buildings must be designed for volatility, not historic weather patterns.

The UN’s warning that climate impacts could displace millions across South Asia raises direct implications for environmental sustainability in construction.

Large-scale migration would intensify pressure on housing delivery, infrastructure finance, sustainable urban development and supply chains for low carbon construction materials. Adaptation is now a construction pipeline issue, requiring life cycle thinking in construction, robust building lifecycle performance and a clearer link between resilience, life cycle cost and whole life carbon.

Materials innovation is moving towards the circular economy in construction. Plans for a wind turbine recycling facility at the Port of Inverness show renewable infrastructure confronting end-of-life reuse in construction. The sector’s claims on circular economy performance will increasingly depend on measurable circular construction strategies, resource efficiency in construction and sustainable material specification, not marketing language. Embodied carbon, embodied carbon in materials and the carbon footprint of construction must be assessed alongside operational energy if net zero carbon buildings and net zero whole life carbon targets are to be credible.

Research converting waste plastics, packaging and old CDs into polymer networks that harvest moisture from air points to future green building products and construction-adjacent materials for water-stressed regions. The science remains early stage, yet it supports the wider move towards low embodied carbon materials, renewable building materials where appropriate, and practical eco-design for buildings.

Laboratory findings showing duct tape outperforming sandbags as a flood defence reinforce a key lesson for sustainable architecture: resilience can come from inexpensive, rapidly deployable measures as well as major green infrastructure. The direction is clear. Sustainable construction is expanding beyond carbon accounting into whole life carbon assessment, lifecycle assessment, low carbon design, circular economy principles and climate practicality. The strongest projects will combine energy-efficient buildings, lower embodied carbon, carbon footprint reduction and durable adaptation to a harsher world.
