Each year, as snow and ice melts from the peaks of the Alps, young bearded vultures take their first flights. Fending for themselves for the first time, they are looking for food. Bearded vultures are the only animal with a diet of almost all bone.
But a century ago, these vultures would not have been seen along the European mountain range. The local population was driven extinct, as bounties were placed on their heads, since people believed they snatched and killed lambs and even small children. The last wild bearded vulture in the Alps was shot and killed in the Aosta Valley in Italy in 1913.
Thanks to a reintroduction project, led by the Vulture Conservation Foundation (VCF), populations are now rebounding. In 1986, VCF started releasing vultures raised in captivity into the wild, and since then it has released 264 birds in the Alps. The alpine population is now self-sustaining, with 522 wild fledglings born since 1997. The birds were declared a protected species by the EU in 2009, and in France, hunting one carries a maximum penalty of €150,000 ($206,000) and three years in prison.
Today, VCF estimates there are up to 460 bearded vultures in the Alps, with 61 wild birds born in 2024. Where once farmers hunted the "gypaète barbu" or "lammergeier" as they are known in French and German, now hikers turn their eyes skyward, hoping to catch a glimpse of these birds that came back from the brink.

The UK’s sustainable construction agenda is shifting from headline innovation to delivery at scale, with retrofit, electrified heat and climate resilience now central to decarbonising the built environment. The National Retrofit Hub’s call for a stronger retrofit system highlights a persistent gap between ambition and implementation: reliable skills, coherent standards, trusted advice and financeable programmes are still needed to cut the carbon footprint of construction across existing building stock.
Retrofit strategies must be judged through whole life carbon assessment, embodied carbon, life cycle cost and lifecycle assessment, rather than short-term capital spend alone. Sustainable building design now depends on building lifecycle performance, low carbon design and sustainable material specification, including environmental product declarations (EPDs), low embodied carbon materials and greater resource efficiency in construction.
Nesta’s analysis that electricity bills are rising more slowly than gas strengthens the case for heat pumps, electrified building services and energy-efficient buildings. If the price gap continues, low carbon building upgrades will become easier to justify through household running costs as well as carbon footprint reduction. Net zero carbon buildings and net zero whole life carbon outcomes will rely on this practical alignment between policy, affordability and performance.
Climate adaptation is becoming part of environmental sustainability in construction. Planting, shading, passive cooling, ventilation and green infrastructure are now essential components of sustainable design and eco-design for buildings, not optional enhancements. The sector’s response to hotter summers must avoid locking in high-energy cooling demand and instead prioritise resilient, low-impact construction.
For commercial property owners, the next phase of ESOS must turn audits into investable decarbonisation plans. BREEAM, BREEAM v7, circular economy principles and circular construction strategies can help move projects from compliance to measurable performance. Sustainable building practices, end-of-life reuse in construction and circular economy in construction will define whether green construction becomes a scalable operating model or remains a collection of isolated initiatives.
