Shipping & Maritime Emissions

Flag state arbitrage: 73% of tonnage registered in Panama, Liberia, Marshall Islands. Heavy fuel oil is the dirtiest fossil fuel in commercial use. IMO 2050 targets are non-binding.

Reading welfare beta
Welfare beta, written as βW and pronounced beta W, means annual system-welfare loss divided by annual industry revenue, written as Π and pronounced capital pi. Revenue is the denominator, never profit; ΔW and Π must use the same domain, same time period, and same activity boundary. See the welfare-beta methodology manual.

Flag State Evasion Floor (Institutional Private-Systemic Tension). Institutional correction is feasible through IMO regulation and port state control.

PLAIN ENGLISH

Maritime shipping transports 80% of world trade while killing 250,000 people annually from air pollution. The scrubber loophole transfers $50-80B per year from atmosphere to ocean. Flags of convenience allow shipowners to register in jurisdictions with minimal environmental standards. The flag is a fiction. The emissions are real.

EXECUTIVE SUMMARY

Global maritime shipping generates $969 billion in annual revenue but imposes $1.30 trillion in welfare costs through seven channels: climate damage, premature mortality, marine ecotoxicity, invasive species, underwater noise, and governance failure. The system beta (βW) is 1.34, meaning each dollar of revenue destroys $1.34 in welfare. The system-adjusted payoff is -$331 billion. The break-even mit

SOURCE QUESTIONS

WHY THIS MATTERS

For the economist
Classified Intractability. The source-reported candidate beta-W of 1.34 is the average system-welfare loss per dollar of industry revenue. Its channel inputs, denominator, and uncertainty packet still require independent admission.
For the regulator
The constraint is institutional, so a well-designed rule can reach a better outcome. Check whether a proven policy model already exists for this domain.
For the executive
This is where a privately efficient decision can degrade the system the business depends on. The governance question is which decision records would make that system cost visible before it is normalized.
For the teacher
An on-site HTML deck and the expanded curriculum cover the argument, the evidence, and the measurement. Use the deck as a self-contained class session, then route deeper through the 45-50h core course or 100+h full curriculum.
For the affected community
In plain terms: who gains from the current arrangement, who pays for it, and what rule change would alter that split. The summary states each without jargon.

Welfare beta is shown on the same scale for each card: annual system-welfare loss divided by annual industry revenue, with both measured on the same domain, same time period, and same activity boundary.
