Star Bulk Carriers’ carbon intensity has increased as charterers asked its bulkers to speed up.
The US-listed Greek bulker owner said the fleet’s annual efficiency ratio (AER) rose to 3.43 last year from 3.25 in 2020.
AER is defined as the ratio of the annual CO2 emissions of a ship divided by the product of the distance sailed and the deadweight, expressed in grams of CO2/dwt-mile.
