Abstract

fetched live from OpenAlex

Metal-related production activities are essential to the low-carbon energy transition but can generate significant social and environmental impacts that influence project success and public acceptance. The MetalliCan dataset compiles and structures data from 23 open datasets and over 150 reports from more than 40 companies in metal-related sectors, offering a high-resolution, site-specific foundation for sustainability impact analysis in Canada. It was constructed following a systematic and reproducible procedure to integrate heterogeneous data sources at the finest granularity possible and ensure traceability and interoperability. MetalliCan covers 48 commodities and 270 domestic sites including active mines, smelters and refineries, as well as advanced projects. It contains information on environmental dimensions-e.g. greenhouse gases, pollutants, water, land, material use and waste-and social dimensions-e.g. affected population, conflicts, protected lands, future water risk and climate conditions. The code and dataset are openly accessible and can be exploited for industrial ecology research, such as life-cycle assessment, material flow analysis and environmental-extended input-output, as well as criticality, social and prospective studies.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
