“With the IMO’s Arctic ban on the use and carriage of heavy fuel oil on the horizon, and measures to reduce black carbon emissions from shipping currently under discussion at the IMO, Carnival’s decision to not use heavy fuel oil lays down a challenge to all Arctic shipping operators. Banning the world’s dirtiest fuel from Arctic shipping is the simplest and easiest way to reduce the risks of long-lasting, damaging oil spills, and will result in a significant reduction in emissions of black carbon, which exacerbates sea ice melt when it settles on snow and ice. Now it’s up to Arctic operators to meet Carnival’s challenge, by making the switch to cleaner fuels.” -Dr. Sian Prior, Lead Advisor to the Clean Arctic Alliance
