How “green” is very low sulphur fuel oil (VLSFO)?

in Trends, Maritime Knowledge by

In recent years, international shipping has increasingly been subjected to criticism for its environmental record. It was in this context that the regulation issued by the International Maritime Organisation (IMO) prohibiting vessels from burning fuel with more than 0.5% sulphur content from 1 January 2020 onwards met with a generally favourable reception. As most ocean-going vessels had previously been burning fuel oil with a sulphur content of 3.5%, it was generally assumed that the very low sulphur fuel oil (VLSFO) would have a positive environmental impact, especially when ships are in port. So how about an initial fact check?

Which vessels emit the most GHG?

in Maritime Knowledge by

Three vessel types were responsible for around three-quarters of worldwide CO2 emissions in 2012. There is little reason to doubt that the Big Three are still responsible for a similar share in 2020. FleetMon provides a global overview of CO2 emissions per vessel type.

Greenhouse gas (GHG) emissions from commercial shipping are increasingly grabbing the headlines. Like aviation, shipping had been excluded from climate negotiations because it is an international activity, while both the 1997 Kyoto Protocol and the 2015 Paris Agreement involved national pledges to reduce greenhouse gases. But as ships move around 80% of global trade in volume terms, there is a growing consensus about the need to tackle shipping’s CO2 emissions.
