Abstract

fetched live from OpenAlex

Alberta emits more greenhouse gases (GHGs) than any other province in Canada, despite having only the 4 th largest population.Alberta's transportation sector produces 16% of these emissions, but has received little recent policy attention.I performed an index decomposition analysis of GHGs from Alberta's road transportation sector from 1990-2010, in order to design policies that maximally reduce transportation emissions.After comparing Alberta's results with those for B.C. and Quebec, I determined that policies should focus on three areas: reducing freight transportation volume, improving fuel efficiency of freight vehicles, and increasing use of low-emission fuels.I then suggested several policies to meet these objectives, and evaluated them for effectiveness, government affordability, and political acceptability.Finally, I recommended the simultaneous implementation of a new fuel tax and the mandatory use of speed limiters for heavy trucks as an effective set of short-term policies to reduce emissions.

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.
