Abstract
Canada's ratification of the Kyoto Protocol has focused attention on the importance of accurately estimating emissions of greenhouse gases (GHG) from all sectors. An inventory of emissions of greenhouse gases from Canadian municipal wastewater treatment plants was prepared using a life-cycle approach. Both on-site emissions at the treatment facility due to the biological processes used and fossil fuels consumed for energy and heat and upstream emissions related to off-site production and transmission of fuels and the off-site production of electricity for the plant were included. For the year 2000, the on-site methane (CH 4 ) emission rate from Canadian municipal wastewater treatment facilities was estimated at 1600 Mg/year. The total on-site emission rate of carbon dioxide (CO 2 ) was estimated at 669 100 Mg/year, but the estimated total CO 2 equivalent emissions rose to 1 048 500 Mg/year once upstream emissions were included. Clear abatement strategies related to more efficient energy use and energy recovery can be identified once accurate GHG emissions inventories are in place.Key words: municipal wastewater treatment, life-cycle approach, greenhouse gas emissions, anaerobic processes.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
