Energy efficiency and the the reduction of GHG emissions from ships


The MARPOL Convention addresses air pollution and emissions from ships deals under Annex VI, first adopted in 1997.  

A revised  Annex VI was adopted in 2005 and it entered into force in  2010, phasing in a progressive reduction in sulphur oxide (SOx) from ships and further reductions in nitrogen oxide (NOx) emissions from marine engines. Amendments adopted in 2011 set mandatory measures to reduce emissions of greenhouse gases (GHGs) from international shipping, with the Energy Efficiency Design Index (EEDI) made mandatory for new ships, and the Ship Energy Efficiency Management Plan (SEEMP) made a requirement for all ships. These amendments enter into force on 1 January 2013​


The amendments to MARPOL Annex VI Regulations for the prevention of air pollution from ships, which entered into force on 1 January 2013, add a new chapter 4 to Annex VI on Regulations on energy efficiency for ships to make mandatory the Energy Efficiency Design Index (EEDI), for new ships, and the Ship Energy Efficiency Management Plan (SEEMP) for all ships.
