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.

Low‑carbon construction materials that once featured only in research pilots are now being deployed across major European projects, signalling a tangible shift towards sustainable building design and environmental sustainability in construction. The European Patent Office refurbishment in Vienna integrates Holcim’s ECOPact concrete and ECOCycle® technologies to minimise embodied carbon while demonstrating architectural excellence. The project exemplifies the practical application of whole life carbon assessment and lifecycle assessment, setting a benchmark for net zero carbon buildings and low carbon design across Europe.
In the UK, construction supply chains are increasingly defined by circular economy principles and resource efficiency in construction. Record renewable energy generation is enabling low carbon building sites powered by cleaner electricity, and the emergence of electric maintenance fleets underscores the shift to carbon neutral construction. The economic rationale for decarbonising the built environment is reinforced by a recent study linking reduced emissions to a measurable “clean air dividend” that enhances life cycle cost outcomes for both public health and infrastructure investment.
Financial institutions are embedding climate risk into portfolio management, with pension funds pressing developers to disclose embodied carbon in materials and adopt environmental product declarations (EPDs). This growing demand for transparency is driving sustainable building practices aligned with BREEAM and emerging criteria under BREEAM V7. The Duchy of Cornwall’s move to verify regenerative farming practices points to tighter integration between land management and construction supply chains, connecting healthy soils with lower embodied carbon concrete and renewable building materials that support a circular economy in construction.
The trend is decisive: sustainability has evolved from a narrative into an operational standard defining net zero whole life carbon strategies, green construction performance, and end‑of‑life reuse in construction. Replicating proven models such as Vienna’s will determine how rapidly the built environment achieves coherent, large‑scale transformation toward eco‑friendly construction and measurable carbon footprint reduction.
