We hold ourselves to the Best Available Technology standard, monitor in real time, and put the evidence on the table.
The collection system is engineered to constitute BAT for minimizing seabed disturbance, plume, noise and light — a hard design requirement and a condition of permit approval.
Onboard and in-water sensors track turbidity, currents, noise and habitat continuously. Collection adjusts or stops when monitored parameters cross agreed thresholds.
Monitoring data feeds the Environmental Impact Statement and the regulator's record. We treat transparency as a licence to operate, not a risk.
Independent life-cycle studies comparing nodule-derived metals with land-based mining of the same metals point in one direction. The figures below reflect published third-party assessments for the nodule resource class — shown for context, to be validated against our own programme data.
| Per unit of metal produced | Nodules vs. land mining |
|---|---|
| CO₂-equivalent emissions | up to ~70–75% lower |
| Stored carbon at risk | ~94% lower |
| Solid processing waste | near-zero — no tailings dams |
| Land use / deforestation | no forest cleared, no overburden |
| Megafauna at risk | ~90%+ lower (low abyssal biomass) |
| Child / forced labour exposure | eliminated — no artisanal supply |
Sources: ISO-compliant life-cycle assessments of nodule-derived metals and the Paulikas et al. (2020) "Where should metals for the green transition come from?" study, among public industry materials. Comparative figures vary by metal, method and assumptions.
The honest comparison. The alternative to responsible seabed collection is not "leave it in the ground" — it is expanded land mining of the very same metals, with costs that are already documented: tropical deforestation for nickel laterite, and artisanal cobalt mining linked to hazardous conditions and child labour. Any decision has to weigh the cost of inaction as well as the cost of action.
Deep-sea collection is scrutinised — rightly. Here is how we think about the most common concerns.
