Bridge a ship's annual EU MRV emissions data to its EU ETS Maritime allowance surrender obligation. Inputs: per-voyage-category CO2 (intra-EU, outbound, inbound, at-berth) plus year and EUA price. Outputs: ETS-scope CO2 after the 50% factor and phase-in, allowance obligation in tonnes, EUR cost.
Formula, assumptions, and limits
| Symbol | Meaning | Unit |
|---|---|---|
| Total ETS-scope CO2-equivalent before phase-in | t CO2e/yr | |
| CO2 from intra-EU voyages (EEA port to EEA port) | t CO2/yr | |
| CO2 from outbound voyages (EEA port to non-EEA port) | t CO2/yr | |
| CO2 from inbound voyages (non-EEA port to EEA port) | t CO2/yr | |
| CO2 from emissions at berth in EEA ports | t CO2/yr | |
| CH4 and N2O converted to CO2-equivalent (only from 2026) | t CO2e/yr |
