WSC, together with co-sponsors, has submitted a number of papers giving input to the development of a Carbon Intensity indicator (CII), a new measure based on an operational approach that supports the IMO's objective of reducing the carbon intensity of international shipping by 40% by 2030, compared to 2008 levels.

Shipping bodies BIMCO, CLIA, International Chamber of Shipping, World Shipping Council, along with other industry groups, have submitted a proposal to the International Maritime Organization (IMO), calling for the UN’s regulatory body to bring forward discussions around MBMs by several years.
