Summary

The seminar presents a study published in Nature Ecology & Evolution that models future nickel supply scenarios to 2050, assessing trade-offs between meeting demand for decarbonisation and protecting priority conservation areas. The research compiles data on 487 known nickel deposits and uses a mine-by-mine supply model (PEMS) to simulate production. Results indicate that around half of future nickel production could come from deposits within the top 10% of priority areas for terrestrial biodiversity and carbon storage, with more than half originating from coastal mines upstream of key marine biodiversity hotspots. The study highlights the dominance of laterite deposits in tropical regions, particularly in Indonesia, the Philippines, and New Caledonia, and the associated environmental risks. It also explores the potential role of deep-sea nodules and the implications of conservation policies such as terrestrial no-go areas and a deep-sea mining moratorium. The findings underscore the need to integrate conservation priorities into responsible sourcing and mine development decisions.

Critical Evaluation

Value of the Information & Strength of the Argument

The seminar provides high-value information by presenting a comprehensive, data-driven analysis of future nickel supply and its environmental trade-offs. The argumentation is solid, grounded in a peer-reviewed study with transparent methodology. The speakers clearly explain the model’s assumptions, data sources, and sensitivity analyses, strengthening the credibility of their conclusions. They effectively argue that current trends in nickel mining, particularly the shift to tropical laterites, pose significant risks to biodiversity and carbon storage, and they quantify these risks. The discussion of conservation policies and deep-sea mining adds depth, showing a balanced consideration of potential solutions.

Contribution & Novelties

The study provides a novel, global, mine-by-mine supply scenario model for nickel that quantifies the trade-offs between meeting future demand and protecting priority conservation areas. It highlights the significant overlap between future nickel production and high-priority biodiversity and carbon areas, and the often-overlooked coastal impacts. The research also explores the implications of conservation policies and deep-sea mining, offering new insights for responsible sourcing and mine development.
