3rd workshop on marine black carbon emissions: Measuring and controlling BC from marine engines

GHG emissions

This invitation-only workshop was held in Vancouver, BC, Canada on September 7th and 8th, 2016. The International Council on Clean Transportation hosted the workshop in collaboration with Environment and Climate Change Canada. It was the third and final workshop designed to inform a two-year project on marine black carbon (BC) emissions funded by the Climate and Clean Air Coalition (CCAC), an international cooperative partnership of 50 country partners and more than 60 intergovernmental and non-governmental organizations to promote strategies to reduce emissions of short-lived climate pollutants, including BC.

The first workshop, held at the Environment Canada River Road Air Quality Laboratory in Ottawa, Canada, in September 2014, brought together 35 in-person participants and multiple remote attendees, representing 21 organizations and 10 countries. One key outcome of the first workshop was a consensus definition of marine BC for research purposes. Another outcome of the first workshop was identifying next steps for appropriate BC measurement and sampling protocols.

The second workshop convened 30 in-person attendees and one remote participant representing more than 20 organizations. The group consisted of international experts on (1) BC measurement and reporting protocols; (2) BC detection instruments; and (3) BC emissions factors. The ultimate goal of the workshop was to achieve consensus on a recommended black carbon measurement approach including appropriate testing protocols, instrumentation, and reporting requirements. These recommendations were applied in a marine BC testing campaign funded by the ICCT under grants from the CCAC and the U.S. Department of Transportation’s Maritime Administration (MARAD).

This third and final workshop convened 27 in-person participants and one remote presenter representing 19 organizations. The goals of this workshop were to: (1) solidify recommendations for marine BC measurement approaches; and (2) identify effective technological and operational strategies to control BC from marine engines. To achieve these goals, the workshop convened international experts on BC to discuss the results of current marine BC testing efforts as well as operational and technological marine BC control strategies. Workshop participants: (1) worked toward consensus on appropriate marine BC measurement approaches; (2) identified priority marine BC control strategies based on scientific evidence; and (3) discussed policy alternatives that could be implemented by individual countries, the IMO, or other forums, in order to reduce marine BC emissions. Workshop outcomes may inform CCAC member state submissions to the IMO on BC appropriate measurement methods and promising control strategies.
