Shipping Climate Costs
What does climate inaction cost the shipping sector — and who pays? The Shipping Climate Costs tool quantifies the annualized economic damage from international shipping's greenhouse gas emissions, attributed to 163 countries as a percentage of GDP. Built on empirical damage estimates from Burke et al. (2026, Nature) and the IMO's own emissions data, it lets users compare the cost of doing nothing against the cost of the Net-Zero Framework — revealing which countries benefit, which bear net costs, and where the break-even lies. Three interactive modes, a user-adjustable social cost of carbon, and a full methodology annex with every assumption documented.
MEPC Policy Explorer
How do the NZF's design choices determine who bears the cost? The MEPC Policy Explorer lets users model how specific decisions still under negotiation — Fund revenue split, disbursement eligibility, delivery efficiency — shape economic outcomes for individual countries. Six interactive policy sliders produce real-time GDP, consumer price, and trade cost impacts, built on the IMO's Comprehensive Impact Assessment (Scenario 24). A companion Pathways module places the NZF in context alongside five alternative proposals currently on the table at the IMO, from adoption as drafted to complete abandonment. Full methodology documentation included.
