Carbon Direct has partnered with Arca to co-develop and market Arca’s Industrial Mineralization (IMin) carbon dioxide removal credits, based on accelerated mineralisation of alkaline mine and steelmaking waste. The technology, validated in an 18‑month pilot with BHP at an active Australian mine, has already secured a 10‑year offtake from Microsoft for nearly 300,000 tonnes of CO₂ and an early prepurchase from Frontier. With 16.5 billion tonnes of suitable legacy waste and 3 billion tonnes produced annually, Arca targets durable (>10,000‑year) CO₂ storage with potential tailings stabilisation co‑benefits.

Construction clients and contractors are starting to embed biodiversity metrics alongside whole‑life carbon assessment, using quantified habitat units and standardised biodiversity net gain (BNG) calculators to track performance through design, procurement and delivery. Supply chains are being asked to evidence habitat creation, connectivity and species outcomes in product data sheets and contracts, linking materials choices and temporary works to measurable on‑site ecological change rather than qualitative statements. For geotechnical and civil teams, this signals future schemes where cut‑and‑fill, drainage, earthworks phasing and landscape design must all be optimised against both carbon and biodiversity targets.

Natural England has approved the Stodmarsh stream enhancement scheme under the Habitats Regulations, unlocking nutrient neutrality credits to support several thousand new homes around Ashford, Kent. The scheme centres on watercourse and wetland improvements in the Stodmarsh catchment to offset additional nitrogen and phosphorus loads from new foul drainage. Planners, drainage designers and geotechnical teams will need to integrate on-site attenuation, SuDS and connection strategies that align with the credit conditions tied to the Stodmarsh enhancement works.
