Bulk carrier ships, 2019
3,675 bulk carrier ships reported to THETIS-MRV for 2019, emitting 17.3 Mt of CO₂. Efficiency is measured as g CO₂/t·nm.
The segment at a glance
Operators
The 2019 public files do not name the companies managing each ship, so operator rankings start in 2024.
Efficiency by ship size
Bigger ships move a tonne of cargo for less fuel, so ships are compared within size bands. Each row is drawn against the segment median.
- Q1: ~16 kt15 g CO₂/t·nm
- Q2: ~25 kt10 g CO₂/t·nm
- Q3: ~35 kt8.52 g CO₂/t·nm
- Q4: ~44 kt6.78 g CO₂/t·nm
- Q5: ~75 kt5.01 g CO₂/t·nm
Q1 to Q5 split the fleet into fifths by average cargo carried, derived from the published ratios.

How fuel is measured
Each ship's monitoring plan names one or more of the four MRV methods.

Notes
- Medians and rankings use 3,360 full-year reports with fuel; part-year and zero-fuel reports count towards totals only.
- THETIS reports time at sea on EU-scope voyages only, not time in port. CO₂ at berth is the closest measure of port activity it publishes.
- Speed and distance are derived from the published ratios; THETIS has no distance column.
