In 2024, Sicily, Italy faced its worst drought in almost 20 years, with nearly empty reservoirs and water rationing affecting up to two million people.  In response, authorities declared a state of emergency, with plans to manage the drought through the reintroduction of desalination plants. Lake Caccamo, located in Sicily, is shown in this Copernicus Sentinel-2 image acquired on 25 July 2024. The lake used to be one of the largest in Sicily, but on 1 August, it reached only 18 million cubic metres in comparison to its capacity of 100 million cubic metres. Globally, droughts have increased by 29% since 2000 due to climate change and unsustainable land management, with water scarcity affecting 30% of Europeans and 20% of land each year. The Conference of the Parties to the UN Convention to Combat Desertification starts on 2 December, and the EU will work to tackle drought, desertification, and land degradation 🇪🇺 🤝 🌎 Open data from the Copernicus Sentinel satellites is essential for monitoring drought and its widespread impacts in affected countries. This information is key to mapping changes in bodies of water and informing management efforts. #ImageOfTheDay #CopernicusEU

Sustainable construction is moving from exemplar projects to market-wide system design, with clean steel emerging as a critical test for whole life carbon policy. A new study suggests the global shift to low-carbon steel could be achieved without raising consumer costs through a revenue-neutral policy model, strengthening the case for low embodied carbon materials in mainstream procurement.

For contractors, developers and public clients, the issue is no longer whether green building materials can perform, but how governments can de-risk low carbon construction materials, reduce the carbon footprint of construction and support net zero whole life carbon targets without shielding high-emission incumbents.

The UK retrofit agenda is becoming central to environmental sustainability in construction. The National Retrofit Hub’s call for a stronger framework comes as electricity and gas prices begin to decouple, improving the life cycle cost case for heat pumps, energy-efficient buildings and electrified homes.

Retrofit policy now needs consistent standards, skilled delivery capacity and consumer protection, backed by whole life carbon assessment, lifecycle assessment and better evidence on building lifecycle performance. Public support for requiring data centres to share waste heat with nearby homes signals a shift in sustainable urban development, treating rejected heat as green infrastructure rather than waste.

Climate adaptation is also reshaping sustainable building practices. GRAHAM’s appointment to deliver the Oxford Flood Alleviation Scheme highlights rising investment in resilience, while reports of roads melting in eastern England expose the environmental impact of construction decisions based on historic weather assumptions.

The built environment is being asked to cut embodied carbon in materials while improving durability against heat, flooding and infrastructure stress. The strongest response will combine sustainable building design, low carbon design, circular economy in construction, sustainable material specification, environmental product declarations (EPDs) and end-of-life reuse in construction. BREEAM, BREEAM v7 and other performance frameworks are likely to play a growing role as clients demand net zero carbon buildings, resource efficiency in construction and credible carbon footprint reduction across the full asset lifecycle.
