This document comments on the outcome of PPR 8 on Black Carbon (BC) and on two options to reduce ship BC emissions other than an immediate switch to distillates in the Arctic – through universal marine engine standards and limiting the aromatic content in marine fuels – and identifies some possible challenges that will need to be addressed
This document provides comments on documents MEPC 76/9/1 (ICES) and MEPC 76/9/2 (Austria et al.) and, based on the information contained in these and other documents, proposes an amendment to the title and scope of the proposed output on the evaluation and harmonization of rules and guidance on the discharge of discharge waters from EGCS into the marine environment.
This document provides comments on the outcome of PPR 8 and proposes an MEPC resolution – a form of non-mandatory instrument addressing Black Carbon emissions from shipping in or near the Arctic.
The co-sponsors raise concerns about the effectiveness of the draft prohibition on the use and carriage for use as fuel of heavy fuel oil (HFO) by ships in Arctic waters proposed in document MEPC 76/3/1.
International NGOs have sent an urgent letter to International Maritime Organization (IMO) Secretary-General, Mr Kitak Lim, calling on him to take action to address international shipping’s climate impact, ahead of Friday’s crucial decision on IMO measures on black carbon emissions in the Arctic.
PPR 8/5/4: Comments on document PPR 8/5 (Submitted by FOEI, Greenpeace International, WWF, Pacific Environment and CSC)
The Reduction on the Arctic of Emissions of Black Carbon from International Shipping: This document comments on document PPR 8/5. It recommends a way forward with respect to a policy option that does not require a measurement method and urges Member States to commence action to reduce the impact on the Arctic of emissions of Black Carbon from international shipping.
This document comments on document PPR 8/5/1 and offers some additional information that the co-sponsors believe is relevant to put the results presented in document PPR 8/5/1 in perspective (The Reduction on the Arctic of Emissions of Black Carbon from International Shipping)
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).
