Abstract :
A cradle-to-gate greenhouse gas assessment of nickel for every major mine, smelter, and refinery worldwide reveals a high degree of variability in emissions per unit of contained metal. The difference between lowest and highest carbon-intensive producers is 70-100 fold, for each stage of production. The results suggest that using global average LCI data for nickel can seriously misrepresent the actual impacts of production.
