On July 15, the committee of the International Maritime Organization (IMO) agreed to require IMO members to adopt the United Nationsʼ Energy Efficiency Design Index for new ships in an attempt to reduce the shipping sectorʼs greenhouse gas emissions. The Marine Environmental Protection Committee will require new ships to adopt a Ship Energy Efficiency Management Plan, which incorporates best practices for fuel-efficient ship operations, including improved voyage planning, optimization of speed and power, and improved fleet management and cargo handling. The Energy Efficiency Design Index requirements will apply to ships only weighing 400 metric tons or more. The world's shipping industry accounts for more than 2.7 percent of total carbon dioxide emissions.
