The vast data centers that power artificial intelligence guzzle huge amounts of energy but they also have another alarming impact, according to new research. They are creating "heat islands," warming the land around them by up to 16 degrees Fahrenheit, and making life hotter for more than 340 million people. There are still big gaps in our understanding of the impacts of data centers, even as they boom in number, said Andrea Marinoni, associate professor with the Earth Observation group at the University of Cambridge, and an author of the study, which has not yet been peer-reviewed. Marinoni and his colleagues decided to dig into one under-researched impact: the heat they release through their energy-intensive processes, including computation and powering cooling systems. To do this, they looked at temperature data over the last 20 years from remote sensors and mapped it against the locations of AI "hyperscalers" — vast data centers that house thousands of servers and can stretch over a million square feet, which have mostly been built within the last decade. They focused on more than 6,000 data centers located away from highly dense urban areas, as surface temperatures around these were less likely to have been affected by other factors, such as manufacturing or the heating of homes. The researchers also filtered out seasonal impacts, global warming trends and other influences. They found surface temperatures increased by an average of 3.6 degrees Fahrenheit after a data center started operations. In extreme cases, nearby temperatures increase by up to 16.4 degrees Fahrenheit. Read more at the link in our bio. 📷: Andrew Caballero-Reynolds/AFP/Getty Images

Global momentum in sustainable construction is reshaping both policy and practice. Offshore wind capacity is set to quadruple by 2035, anchoring the shift toward net zero carbon economies and supporting a built environment driven by decarbonising the construction sector. The UK’s pipeline of more than 700 grid-connected projects signals progress towards net zero whole life carbon performance, where every aspect of infrastructure delivery is assessed through whole life carbon assessment and life cycle cost analysis.

Despite advances in renewable power, non-domestic buildings continue to underperform on emissions reduction, emphasising the urgent need for retrofit strategies based on embodied carbon measurement and lifecycle assessment. The Building Controls Industry Association identifies this as a critical barrier to achieving energy-efficient buildings and net zero carbon buildings aligned with sustainable building design and environmental sustainability in construction.

Early contractor involvement is emerging as a proven method to improve resource efficiency in construction and reduce overruns, aligning procurement with circular construction strategies and sustainable building practices. Confidence in global carbon accounting remains unsettled following resignations within the Greenhouse Gas Protocol, casting doubts on the accuracy of embodied carbon in materials data used for environmental product declarations (EPDs) and whole life carbon assessments that inform BREEAM and BREEAM V7 frameworks.

Material flows define the next frontier of sustainable design and low carbon construction materials. Europe’s unchecked aluminium scrap exports jeopardise circular economy in construction goals, undermining the reuse of low embodied carbon materials and low-impact construction systems that enable end-of-life reuse in construction. In the UK, Enva’s £7.5 million investment in electrical recycling illustrates how eco-friendly construction and circular economy practices can strengthen domestic supply chains for renewable building materials.

The shift toward sustainable architecture and green infrastructure extends to digital transformation. London’s strategy to attract energy-efficient, low carbon data centres reflects a broader commitment to carbon neutral construction and sustainable urban development. With eco-design for buildings now embedded in planning, sustainable material specification and life cycle cost thinking in construction are becoming defining features of the modern built environment. The sector is moving from aspirational sustainability to measurable decarbonisation—embedding whole life carbon and circular economy principles as core drivers of the future of construction.
