U.S., Canada commit to methane reductions from oil and gas production
Bibliographic record
Abstract
U.S. President Barack Obama and Canadian Prime Minister Justin Trudeau earlier this month jointly committed their nations to reduce methane emissions from existing oil and natural gas sources by 40 to 45% from 2012 levels by 2025. Their agreement notes that the oil and gas sector is the world’s largest source of industrial emissions of methane, a potent greenhouse gas. The Environmental Defense Fund, an activist group, says the oil and gas industry is responsible for 90% of U.S. methane emissions. Obama says EPA will begin developing regulations and start a formal process to require companies to provide data on methane emissions. Canada will propose rules by early 2017. In the past, EPA proposed to limit methane emissions from various sources, including oil and gas production facilities, but ran into industry opposition. The American Petroleum Institute says regulations would curb the current U.S. oil and gas bonanza, adding that the

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
