Carbon offsetting — compensating for CO2 emissions by reducing them in unrelated sectors — will always have a place in decarbonising maritime, some observers say.

Others contend that the practice, which has been long adopted by the airline industry, gives misleading results and will be unnecessary in a sector that will be carbon-free one day.

KPI OceanConnect, a Danish bunker provider founded in 2020 between the merger of KPI Bridge Oil and OceanConnect, is a strong backer of the concept, having set up a carbon-offsetting service in July for its customers.
