GreenRoc Strategic Materials (AIM:GROC), a company developing critical mineral projects in Greenland, said an independent cradle-to-gate assessment estimates its planned Amitsoq graphite output would generate 1.60 kg of carbon dioxide equivalent per kg of coated spherical purified graphite (CSPG).
That figure sits at the lower end of benchmark estimates for comparable anode active material products cited in GreenRoc's 2024 pre-feasibility study, which drew on data from Benchmark Mineral Intelligence covering four other planned or operating producers.
"The fact that our product is modelled to be at the lower end of the independent estimates set out in our 2024 PFS is a solid foundation for providing Europe with a highly competitive product in terms of carbon emissions," said CEO Stefan Bernstein.
Downstream processing accounts for roughly 87% of the total footprint, with electricity used in micronising, coating and purification the largest single contributors.
Mining and production of graphite concentrate at the Amitsoq site in southern Greenland contributes approximately 9%, while transport adds roughly 4%.
The model, built using ISO 14067:2018-aligned methodology, assumes a Scandinavian electricity supply, reflecting GreenRoc's strategy of locating downstream processing in the region.
The assessment has not undergone external review and is intended as an indicative baseline.
GreenRoc plans to refine the model, testing alternative energy sources and reagent choices, as the project advances toward a definitive feasibility study.
News Intelligence what this means for the company
GreenRoc's independent carbon footprint assessment for its planned Amitsoq graphite anode material came in at 1.60 kg CO₂e per kg of finished product, positioning it at the lower end of industry benchmarks drawn from four other producers cited in the company's 2024 pre-feasibility study. The assessment, built on Scandinavian electricity assumptions and ISO 14067 methodology, identifies downstream processing (micronising, coating, purification) as the dominant emissions driver at 87%, with mining contributing 9% and transport 4%. The company flags the assessment as indicative and unreviewed, and plans to test alternative energy sources and reagents as the project advances toward a definitive feasibility study.
The carbon intensity result supports GreenRoc's competitive positioning in a market increasingly sensitive to anode material emissions, but the assessment remains preliminary and unvalidated. Material progress on the project depends on advancing toward the definitive feasibility study and securing downstream processing capacity in Scandinavia as modeled.
