Abstract

fetched live from OpenAlex

A carbon footprint analysis following the ISO 14067 standard reveals that Canadian field crops have generally much lower footprints than those of international competitors due to differences in soil carbon flux and nitrous oxide emissions. Transportation-to-market of Canadian crops is proportionately important, but related emissions are often more than offset by low production-related emissions. In extreme cases, Canadian crops could be shipped to western European markets an additional 17 times before their carbon footprint would break even with crops grown in Europe. Greenhouse gas emissions of major commodity field crops are of increasing interest to diverse stakeholders. A carbon footprint analysis following the ISO 14067 standard reveals key drivers of, and differences in, emissions for selected field crop production and transport to market between Canada and other countries.

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.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
