In broad daylight, law enforcement officers raid a warehouse on the outskirts of the city of Sukhumi in Abkhazia, a Russia-backed breakaway Georgian region. No one's there; no drugs or weapons either. Only a large cooling cabinet containing dozens of electronic devices. This is a cryptocurrency mine. A video of the raid was posted in December by the Abkhaz press service, one of many it has posted to YouTube since 2021. Crypto mining is banned in Abkhazia, yet for years this energy-intensive industry has flourished, attracted by the region's cheap hydropower. For Abkhazia, it comes at a cost. The region typically faces seasonal power shortages as water levels drop in the winter, but they have become more disruptive because of crypto mining, which is sucking up electricity 24 hours a day. What's happening in Abkhazia is extreme but it's indicative of a global trend. The crypto industry, while always volatile, is booming and is hungry for power. "Electricity is the largest cost input to crypto," said Theresa Sabonis-Helf, an energy security professor at Georgetown University. To get their hands on it, many miners — both illegal, like those in Abkhazia, as well as legally-operating companies — are looking to places where they can tap into cheap electricity, often those with plentiful renewables. Experts warn it can come at a cost for local people, exacerbating shortages and diverting clean energy. Tap the link in @cnn bio for more. 📸 : ImageBroker/Shutterstock

Momentum in sustainable construction is now driven by tangible progress in materials and methods rather than declarations. The focus on reducing embodied carbon in materials and undertaking robust whole life carbon assessment is reshaping how developers, architects and engineers define sustainable building design. Initiatives such as the Reducing Plastics in Construction Summit reinforce the value of renewable building materials, eco-design for buildings and circular economy in construction frameworks to eliminate petroleum-based polymers and improve resource efficiency in construction.

Biobased composites, recyclable resins and modular approaches are being evaluated through lifecycle assessment tools that can accurately measure the carbon footprint of construction and inform sustainable material specification throughout each project stage. Digitisation is rapidly becoming integral to low carbon design and energy-efficient buildings. Advanced platforms now enable unified modelling of cost, performance and carbon, aligning lifecycle cost optimisation with environmental sustainability in construction.

TM2 Bygg’s software-led method illustrates how low carbon building processes built on data-driven insights help achieve net zero carbon buildings and deliver improved building lifecycle performance. At the policy level, regulators are reinforcing requirements for measurable reductions in embodied carbon and clear evidence of net zero whole life carbon outcomes. These shifts point toward an industry-wide transformation grounded in whole life carbon transparency and the adoption of BREEAM v7 and other sustainable building practices to standardise reporting.

The result is a market that values circular construction strategies, end-of-life reuse in construction and environmental product declarations (EPDs) as verification of a project’s environmental impact of construction. New renewable energy infrastructure, including next‑generation geothermal systems, could redefine the carbon footprint reduction potential of green building materials and low carbon construction materials. As baseload renewables expand, achieving carbon neutral construction and sustainable urban development becomes increasingly viable. The sector is moving beyond pilot projects toward a mature phase of green construction, integrating life cycle thinking in construction and decarbonising the built environment as core business practice.
