A new study finds IMO’s low-sulphur fuel mandate actually boosts dangerous black carbon emissions in the Arctic
Heavy fuel oil commonly used in shipping is bad for the Arctic. But a switch to low-sulphur fuel appears to be making the problem of black carbon even worse.
The International Maritime Organization has mandated the use of very low sulphur fuel oil (VLSFO) in marine shipping starting January 1, 2020. This regulation is part of IMO’s 2020 program aimed at reducing sulphur emissions from marine transport by 80 percent. In contrast to heavy fuel oil (HFO), which contains up to 3.5 percent sulphur, VLSFO may only contain 0.5 percent.
