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.

PPR 8/5/3: Comments on document PPR 8/5/1 (IBIEC and IBIA)

PPR 8/5/3: Comments on document PPR 8/5/1 (IBIEC and IBIA)

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)

PPR 8/5/2: Comments on document PPR 8/5/1

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

Final results of a Black Carbon measurement campaign with emphasis on the impact of the fuel oil quality on Black Carbon emissions

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).

Comments on document MEPC 75/10/Add.1, paragraph 3.5 on draft amendments to MARPOL Annex I to incorporate a prohibition on the use and carriage for use as fuel of heavy fuel oil by ships in Arctic waters

MEPC 75/10/7: Comments on document MEPC 75/10/Add.1, paragraph 3.5 on draft amendments to MARPOL Annex I to incorporate a prohibition on the use and carriage for use as fuel of heavy fuel oil by ships in Arctic waters

In response to document MEPC 75/10/Add.1, the co-sponsors raise concerns about the impact and effectiveness of the draft prohibition on the use and carriage for use as fuel of heavy fuel oil (HFO) by ships in Arctic waters. Recently published work indicates that only 30% of HFO carriage and 16% of HFO use would be banned when the regulation comes into effect, and that it is likely that the amount of HFO carried and used in the Arctic will increase following the ban taking effect.

Comments on document MEPC 75/10/Add.1, paragraph 3.4, on reducing the impact on the Arctic of Black Carbon emissions from international shipping

MEPC 75/10/6: Pollution Prevention and Response: Comments on document MEPC 75/10/Add.1, paragraph 3.4, on reducing the impact on the Arctic of Black Carbon emissions from international shipping

In response to documents MEPC 75/10/Add.1 and MEPC 75/7/15 and in light of the crisis unfolding in the Arctic, along with the fact that Black Carbon emissions from shipping continue to grow both globally and in the Arctic, the co-sponsors propose the development and adoption of an MEPC Black Carbon resolution. The resolution would set out recommended interim measures pending completion of IMO work to identify and implement one or more Black Carbon abatement measures. The annex includes elements that should be considered for inclusion in such a resolution.

Reduction of GHG Emissions from Ships: Fourth IMO GHG Study 2020 – Final report

MEPC 75/7/15: Reduction of GHG Emissions from Ships: Fourth IMO GHG Study 2020 – Final report

Highlights The greenhouse gas (GHG) emissions – including carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), expressed in CO2e – of total shipping (international, domestic and fishing) have increased from 977 million tonnes in 2012 to 1,076 million tonnes in 2018 (9.6% increase). In 2012, 962 million tonnes were CO2 emissions, while in 2018 this amount grew 9.3% to 1,056 million tonnes of CO2 emissions. The share of shipping emissions in global anthropogenic emissions has increased from 2.76% in 2012 to 2.89% in 2018. Under a new voyage-based allocation of international shipping, CO2emissions have also increased over this same period from 701 million tonnes in 2012 to 740 million… Read More »MEPC 75/7/15: Reduction of GHG Emissions from Ships: Fourth IMO GHG Study 2020 – Final report
