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 🧵

🧵 (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.

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 👇

French organizations Carbone 4 + ECF launch this essential report on "imported emissions".

It's essential because a significant part of global emissions are embedded in trade and interdepencies, raising questions about responsibilities and partnerships for climate.

There's been a lot of debate about what economic theory says regarding tariffs.

Drawing on my research with quantitative economic models, here's a thread explaining the textbook logic for why "tariffs are bad" for revenue generation.

My Trade Secrets today. When Trump replaces Biden, America’s trading partners fear he will impose high unilateral tariffs, treat WTO rules with contempt and coerce them with threats of trade restrictions.

“No change there then” would be an exaggeration, but not a grotesque one.
