This past January, the International Maritime Organization (IMO) made long-anticipated progress on the definition of black carbon from shipping. After four years of agonizing debate, the subcommittee on Pollution Prevention and Response (PPR) recommended that the Maritime Environment Protection Committee (MEPC) accept the definition used in this landmark paper by Tami Bond et al., and move forward with its work plan on black carbon. Next steps include developing a standardized way to measure black carbon and investigating potential control options.
