The Clean Cargo Working Group (CCWG) is focused on improving environmental performance in marine container transport using standardized tools for measurement, evaluation, and reporting. The CCWG was established in 2003 by BSR (Business for Social Responsibility) and founding industry members. CCWG is composed of a member-elected steering committee and several working teams. BSR serves as the neutral secretariat, data manager, and expert facilitator. Data from more than 20 of the world’s leading ocean carriers are reported to CCWG, representing more approximately 85 percent of global ocean trade (based on TEU capacity represented by CCWG carrier members in February 2014, as measured by Alphaliner).
