Shipping consultancy Drewry is trying to shine a light on new bunker adjustment factor (BAF) fees with a new index.

It wants to bring greater transparency to fuel costs as the IMO 2020 low-sulphur deadline approaches on 1 January.

The bunker index tracker is a response to confusion expressed in recent months by both shippers and forwarders over surcharges introduced by container lines as they switch to the more expensive eco-fuel, Drewry said.
