What are we waiting for? The time to act on plastic pollution is now
Bibliographic record
Abstract
The reduction of plastic production was a contentious issue during the fourth session of the Intergovernmental Negotiating Committee on plastic pollution (INC-4) held in Ottawa, Canada, from April 23 to 29, 2024. The proposal to reduce primary plastic polymer production by 40% during 2025–40 was backed by several countries in the Western Pacific region, including Australia, Fiji, and the Philippines. In preparation for the final session (INC-5) scheduled for November 25–December 1, 2024 in Busan, South Korea, intersessional work will focus on implementation and funding of a global treaty on plastic pollution.

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.
