Black carbon is the second largest contributor to shipping’s climate impacts, representing 7–21% of CO 2-equivalent emissions from the global shipping sector on a 100-year and 20-year timeframe, respectively. Presum-ably, the point of a GHG strategy is to reduce climate pollution in all forms, whether or not it’s a gas or a particle.

First, during the negotiations, several oil-producing countries argued that black carbon is not a “gas” and therefore it should not be included in a GHG strategy. If black carbon is such a big problem, why isn’t it included in IMO’s GHG strategy? There were two arguments for omitting it.
