The Guide to IMO is a resource for anyone looking to get a crash course in what the International Maritime Organization (IMO) is and how it operates.
A new study shows that blended low sulphur fuels (VLSFO) developed to meet the sulphur cap could contain high levels of aromatic compounds which lead to significant increases in black carbon (BC) emissions.
The use of heavy fuel oil by ships crossing the Arctic creates the risk of a catastrophic spill – which would be practically impossible to clean up. Worse still, when heavy fuel oil (HFO ) is burned in ship’s engines, the black carbon emitted falls onto Arctic snow or ice.
Infographic detailing the environmental and social impacts of a HFO spill; the economic impacts of a ban on HFO in the Arctic.
Our civilization has developed during a period of incredibly stable climate over the past 10000 years. The predicted changes for the next few hundred years are in steep contrast. The Arctic is the most important early warning system for climate change on our planet. Rapid loss of Arctic sea ice is a clear indicator of changing climate.
This infographic details how many ship operating in the Arctic use heavy fuel oil (HFO) – the residual waste of the petroleum refining process. It is extremely viscous and virtually impossible to clean up in the case of a spill. It also looks at Black Carbon, a critical contributor to human-induced climate warming, especially in the Arctic. The combustion of heavy fuel oil produces high levels of Black Carbon.
To address the impact of ship Black Carbon (BC) emissions on the Arctic, the International Maritime Organization (IMO) has been tasked with developing a definition for black carbon, deciding on best methodology for measuring black carbon, and identifying abatement options. A considerable number of black carbon abatement options exist with varying reduction potential of BC emissions. Some are readily available, some in development, some expensive, some cheaper. This infographic goes through some of the most effective abatement options and depicts their advantages and drawbacks based on the most up to date scientific literature.
Submitted by to PPR7/8 by FOEI, WWF, Pacific Environment and CSC. This document discusses the implications for the Arctic of a recent study indicating that blended low sulphur residual fuels that have been developed to meet the IMO 2020 requirement will result in a significant increases in Black Carbon emissions, and calls on the IMO to mandate an urgent switch to distillates for ships operating in the Arctic to avoid a sharp rise in emissions of short-lived climate forcers in this vulnerable area.Download document (pdf): PPR 7/8/3: The need for an urgent switch to distillates for ships operating in the Arctic
PPR 7/8/2: PPR7 Submission: The need for urgent action to stop the use of blended low sulphur residual fuels leading to increases in ship-source Black Carbon globally
New blended low sulphur fuels designed to meet IMO 2020 0.50% global sulphur limit will result in significant increases in ships’ Black Carbon emissions.
PPR 7/14/6: Comments on document PPR 7/14/4, “Draft language for a ban of use and carriage of heavy fuel oil as fuel by ships in Arctic waters”
This document sets out the views of the co-sponsors on document PPR 7/14/4, “Draft language for a ban of use and carriage of heavy fuel oil as fuel by ships in Arctic waters”. The co-sponsors support the process outlined in document PPR 7/14/4 but do not agree that delays or exemptions to a ban are necessary.
