The critical system of ocean currents which loops around the Atlantic Ocean is weakening and could be far closer to collapse than previously thought, according to two new studies — an event which would have catastrophic impacts on the planet's weather and climate.
The Atlantic Meridional Overturning Circulation, known as the AMOC, functions like a vast conveyor belt, transporting heat, salt and freshwater through the ocean and influencing climate, weather and sea levels around the planet.
A growing body of research suggests it's weakening as human-driven global warming disrupts its delicate balance of heat and salinity, with one study even predicting it could collapse as soon as next decade. But the AMOC is complex and has only been continuously monitored since 2004. Climate models generally agree it's on course to weaken this century, but there is a huge amount of uncertainty about the extent of its decline.
The two new studies — one which focuses on the AMOC's future, the other on its present — provide new and alarming evidence of its decline.

Sustainable construction across Europe is entering a decisive phase defined by measurable accountability and the transparent management of Whole Life Carbon. Standardised energy performance labelling across the continent is transforming the environmental sustainability in construction from a patchwork of national rules into a data-led market for energy-efficient buildings. This shift allows accurate Whole Life Carbon Assessment and encourages the integration of lifecycle assessment into sustainable building design. Regulatory frameworks are expected to influence procurement and disclosure systems, embedding life cycle cost analysis into mainstream planning to support low carbon construction materials and building lifecycle performance.
The ASBP’s report on plastics in construction exposes the embodied carbon in materials that have long dominated the market. Its findings strengthen the case for low embodied carbon materials, renewable building materials, and circular construction strategies promoting resource efficiency in construction. The growing focus on end-of-life reuse in construction aligns with the principles of the Circular Economy in construction, prompting innovation in eco-design for buildings and sustainable material specification. Industry leaders are responding with new models of sustainable building practices that treat embodied carbon as a core design parameter rather than a compliance exercise.
Corporate sustainability coalitions and investors are refocusing capital towards net zero carbon buildings and green infrastructure, accelerating decarbonising the built environment through carbon neutral construction standards. The direction is reinforced by benchmarks such as BREEAM and emerging updates including BREEAM v7, which integrate life cycle thinking in construction and verify environmental product declarations (EPDs). These frameworks push the sector towards low carbon building solutions, sustainable design, and net zero whole life carbon delivery.
The momentum suggests that the world’s largest source of emissions is finally embracing measurable transformation. The carbon footprint of construction is being recast through data, transparency, and circular economy integration. This movement transforms green construction from rhetoric into a quantifiable, accountable system that delivers sustainable architecture capable of genuine carbon footprint reduction and long-term environmental resilience.
