Emissions & OPS Potential
Emissions & OPS Potential description.
CO₂ by port
Estimated tonnes in the period (HFO scenario), with the OPS-avoidable share
CO₂ per berthing hour
Operational carbon intensity per port (t CO₂ / h)
Top 10 emitting vessels
Cumulative estimated CO₂ across all calls in the period (HFO scenario).
| # | Vessel | IMO | CO₂ (t) | Calls | Ports |

Europe benchmark (EU MRV)
Vessels calling at the Brazilian ports that also report verified CO₂ under the EU MRV scheme, compared against the full European fleet.
CO₂ per transport work by ship type (g CO₂ / t·nm)
Lower is more efficient. Median of each fleet.
Model validation, verified EU data
The same fleet that calls at the Brazilian ports reports verified at-berth CO₂ in EU ports (EU MRV 2024). Applying our estimated auxiliary-engine rates to those verified totals implies how many days per year each vessel would have spent at berth in Europe. Plausible durations indicate the model's rates are consistent with verified data.
Validation by ship type
Medians per ship type: our estimated auxiliary rate in Brazil, the verified annual at-berth CO₂ in EU ports, and the implied berth days per year.
| Ship type | Vessels | Our rate (t CO₂/h) | EU verified at berth (t/yr) | Implied berth days/yr |

EU carbon-cost exposure of the fleet serving Brazil
Vessels calling at the Brazilian ports also fall under the EU Emissions Trading System when they trade with Europe. Their verified ETS-scoped CO₂ (EU MRV 2024) priced at the current allowance value shows how much European carbon cost travels with the fleet that serves Brazilian trade lanes.
ETS exposure by ship type
Verified 2024 ETS-scoped emissions of the Brazil-calling fleet. Surrender obligation: 40% for 2024, 70% for 2025, 100% from 2026.
| Ship type | Vessels | ETS CO₂, total (t) | Median per vessel (t) | Median cost (€/yr) |

Methodology note
Every emission figure on this platform covers only the berthing phase and only auxiliary engines: this is the consumption that onshore power supply (OPS) replaces, and the only phase observed at all three ports, which makes the figures directly comparable and directly actionable for electrification planning. Anchorage and manoeuvring are excluded by design (Itaguaí's PSP source has no arrival time). Method: IMO 4th GHG Study 2020, auxiliary_power × berthing_hours × emission_factor, HFO scenario.
