PPR 8/5/2: Comments on document PPR 8/5/1 (ISO)

In terms of overall Black Carbon emissions, it is not seen that setting an H/C limit would address the issues since VLSFOs are generally not prone to aromaticity and furthermore the hydrocarbon structure of a fuel is only one element in the factors which govern BC emissions – The Reduction on the Arctic of Emissions of Black Carbon from International Shipping

PPR 8/5/1: Final results of a Black Carbon measurement campaign with emphasis on the impact of the fuel oil quality on Black Carbon emissions

In this document, the final results of a Black Carbon measurement campaign on a single cylinder 4-stroke medium speed research engine are presented. The aim of the study was to analyse the impact of fuel oil quality on Black Carbon emissions. Furthermore, the composition of the particulate matter in the exhaust gas and a detailed fuel oil analysis of the VLSFOs are presented. The formation of Black Carbon is dominated by the aromatic content and H/C ratio of a fuel and could not be compensated by engine settings (injection timing or pressure). The aromatic fraction of investigated VLSFO fuels were dominated by harmful polycyclic aromatic hydrocarbons (PAH).

IMO and Arctic States Slammed for Endorsing Continued Arctic Pollution

The Clean Arctic Alliance today slammed the decision by the International Maritime Organization (IMO) to approve a ban ridden with loopholes on the use and carriage of heavy fuel oil in the Arctic (HFO), saying that it would leave the Arctic, its Indigenous communities and its wildlife facing the risk of a HFO spill for another decade.

NGOs Urge IMO To Rethink Weak HFO Ban, Demand Stronger Arctic Protection

As the first virtual meeting of the International Maritime Organization’s Marine Environment Protection Committee (IMO, MEPC 75) opens today, the Clean Arctic Alliance implored member states to amend and improve its draft ban on the use and carriage of heavy fuel oil (HFO) in the Arctic or risk implementing a “paper ban” – a weak regulation that will leave the Arctic exposed to greater danger from oil spills and black carbon pollution from HFO in the future, as shipping in the region increases.
