Scientists have looked back in time to reconstruct the past life of Antarctica’s “Doomsday Glacier” — nicknamed because its collapse could cause catastrophic sea level rise.
Experts knew it had been losing ice at an accelerating rate since the 1970s, but because satellite data only goes back a few decades, they didn’t know exactly when significant melting began. Now there is an answer to this question, according to a study published in the journal Proceedings of the National Academy of Sciences.
By analyzing marine sediment cores extracted from beneath the ocean floor, researchers found the glacier began to significantly retreat in the 1940s, likely kicked off by a very strong El Niño event. Since then, the glacier has been unable to recover.

The Royal Institution of Chartered Surveyors has launched a global consultation on sustainable construction standards to address inconsistent adoption of frameworks across markets. This move directly impacts how whole life carbon and embodied carbon in materials are measured and reported. Establishing a consistent whole life carbon assessment is crucial to driving environmental sustainability in construction and setting reliable benchmarks for low carbon building and infrastructure.
A companion RICS report highlights the growing role of digital technology in sustainable building design. Artificial intelligence is shown to improve material optimisation, cut embodied carbon in materials, and reduce the overall carbon footprint of construction. Despite the promise, firms face challenges in digital capability and integration. Improving skills in lifecycle assessment and life cycle thinking in construction will be vital for accurate building lifecycle performance and for delivering successful net zero whole life carbon strategies.
In North America, industry consolidation is signalling a strengthening of sustainable building practices. The acquisition of Gaskins + LeCraw by Pape-Dawson consolidates engineering, environmental surveying, and permitting expertise. This broader skillset supports the delivery of eco-design for buildings, sustainable urban development, and circular economy in construction models. The merger points to stronger capacity to specify low embodied carbon materials and align projects with BREEAM and other sustainable design standards.
Investment in renewable energy directly tied to construction is also expanding. TDK Ventures is backing geothermal innovator Rodatherm, which targets lower carbon footprints in heat supply for energy-efficient buildings. The development of new renewable building materials together with such low carbon construction technologies is key to sustainable building practices. This also ties into wider circular construction strategies and resource efficiency in construction efforts, both central to decarbonising the built environment.
A new agreement between the UK and US to accelerate nuclear power deployment influences long-term sustainable infrastructure planning. Nuclear’s role in the low carbon energy mix intersects with construction sustainability, as large-scale building projects must consider whole life carbon accounting, life cycle cost reporting, and net zero carbon targets. This development places pressure on contractors and designers to adopt green construction strategies and minimise the environmental impact of construction while meeting regulatory requirements.
Advances in ESG data and sustainability reporting tools are also reshaping construction finance. The partnership between Novata and S&P Global Sustainable1 focuses on greater transparency and accountability, reducing risks of greenwashing. Better data on environmental product declarations (EPDs), sustainable material specification, and building lifecycle performance will strengthen confidence in climate-aligned investment. Such precision drives progress towards circular economy goals and builds trust in carbon neutral construction.
