The volcanic system on Iceland’s Reykjanes Peninsula has woken up. Vikings roamed the last time these volcanoes raged. Now, eight centuries later, this slice of land close to the capital city Reykjavik is one of the more densely populated parts of the country. The recent eruptions here are not from “tourist volcanoes,” relatively accessible and typically non-disruptive. They are violent, dangerous and could last centuries. They could also hold the key to a new future. Scientists and engineers are hoping to harness magma’s immense power to produce a new kind of extreme geothermal energy, many times more powerful than conventional. It’s a tantalizing prospect as the world struggles to end its relationship with planet-heating fossil fuels. If the effort succeeds, the implications could reverberate around the world.

Wildfires destroying homes in the Midlands and Shropshire crews moving between fire and flood show why sustainable construction must now treat climate resilience as a core design requirement. Sustainable building design, low carbon design and eco-design for buildings need to account for overheating, fire risk, drainage capacity, defensible space and durable fabric performance.

Whole life carbon, embodied carbon and life cycle cost are becoming inseparable from safety, insurability and asset value, making whole life carbon assessment and lifecycle assessment essential tools for developers, councils and investors.

Karachi’s mangrove loss reinforces the construction value of green infrastructure and nature-based flood protection. Tidal creeks, mangrove belts and resilient coastal landscapes can reduce erosion, store carbon and protect communities, supporting environmental sustainability in construction without relying solely on hard engineering. For sustainable urban development, green construction and eco-friendly construction must prioritise site planning, biodiversity and building lifecycle performance alongside energy-efficient buildings and net zero carbon buildings.

Plans for a wind-turbine recycling facility in the Scottish Highlands point to a more mature circular economy in construction. Renewable infrastructure must address end-of-life reuse in construction, resource efficiency in construction and the embodied carbon in materials, especially composite blades and complex low carbon construction materials. The shift supports circular construction strategies, low embodied carbon materials and net zero whole life carbon targets, aligning with BREEAM, BREEAM v7 and wider expectations for environmental product declarations (EPDs). The strongest signal for decarbonising the built environment is clear: sustainable building practices must measure the carbon footprint of construction across design, use, maintenance and decommissioning.
