Aviation and Climate Protection Flugverkehr und Klimaschutz – Ein Überblick über die Erfassung und Regulierung der Klimawirkun gen des Flugverkehrs
Bibliographic record
Abstract
International air traffic is not yet embedded in international frameworks to reduce anthropogenic greenhouse gas emissions, apart from the EU emission trading system. This paper reviews the state of knowledge on the climate effects due to aviation. Recent findings reveal a much smaller radiative forcing of line-shaped contrails than previously estimated. The greatest uncertainties regarding aviation's climate effects revolve around changes in cirrus cloud properties. The paper addresses issues on how to include aviation in international frameworks on climate protection. Today's proposed methods to cover non-CO 2 effects from air traffic (Radiative Forcing Index and Emission Weighting Factor) are shown to include significant shortcomings that prohibit their application in policy relevant measures. More elaborate techniques are under development. Then, different approaches are presented to exemplify how emissions from international aviation can be allocated to national territories. For Switzerland an estimate based on the residence approach is explained in more detail. Finally, the paper elucidates the measures taken by the European Union to include the aviation sector into its emission trading scheme.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
