Ce faux dilemme occulte le vrai débat, autant politique que scientifique : quel niveau de preuve faut-il atteindre avant d’agir pour protéger la population ? C’est cette question, trop souvent escamotée, que nous proposons de remettre au centre. (3/3)

Le rapport de l’Anses a relancé le débat sur l’exposition au cadmium et la hausse des cancers du pancréas. La discussion s’est polarisée : d’un côté, ceux qui lisent les corrélations comme preuve causale ; de l’autre, ceux qui, au nom de la science, leur dénient tout contenu informationnel. (2/3)

🧵 (1/4) There are four fundamental flaws of the House tax bill. #1 It is fiscally irresponsible; all reputable sources agree. Bond markets & downgrades show US financial fragility; this is a bad time to take on trillions in additional debt toward no useful policy rationale.

Thanks Ludovic! Below is a first breakdown of the pesticides embedded in EU consumption/imports. Some of those forbidden substances are produced in Europe, see www.lemonde.fr/planete/arti... Tracking the whole chain is on the todo list!

5/ We evaluate two policy instruments with distinct WTO compatibility considerations: (1) a Leakage Border Adjustment Mechanism designed to neutralize competitive distortions, and (2) a Phytosanitary Border Adjustment Mechanism which prices pesticide externalities in imports.

Mathieu Parenti @mathieupar.bsky.social · 27/03/2025

Here is a first estimate of the toxicity-weighted phytosanitary footprint of EU consumption

110

Mathieu Parenti @mathieupar.bsky.social · 27/03/2025

4/ We introduce the "phytosanitary footprint" metric to quantify the aggregate pesticide load in agricultural production. This methodology enables assessment of transboundary environmental impacts embedded in trade flows, similar to carbon footprint accounting.

110

Mathieu Parenti @mathieupar.bsky.social · 27/03/2025

3/ Quantitative modeling demonstrates that implementing a unilateral 50% pesticide reduction policy (e.g., Farm-to-fork) without complementary measures would significantly impair EU agricultural competitiveness while facilitating production displacement to regions with less stringent standards.

110

Mathieu Parenti @mathieupar.bsky.social · 27/03/2025

2/ Without safeguards, stricter EU regulations not only fail to achieve global environmental goals but actively tilt the playing field against EU farmers.

Mathieu Parenti @mathieupar.bsky.social · 27/03/2025

1/ NEW RESEARCH: Our study reveals 46% of pesticides embedded in EU agricultural consumption originate from imports, despite imports constituting only 17% of consumption. This includes substances prohibited in the EU. This regulatory gap fuels leakage effects and hurts EU competitiveness 🧵

4/ Key to understanding this issue is the "phytosanitary footprint" - similar to a carbon footprint, it measures the total pesticide load used (directly & indirectly) in producing agricultural goods. It reveals environmental impacts that cross borders through trade 👇
