Rio+20 & IMO

The United Nations Conference on Sustainable Development (UNCSD) took place at Rio from 20-22nd June 2012.  Two themes focused at Rio+20 were a green economy in the context of sustainable development poverty eradication; and the institutional framework for sustainable development. Sustainable development means to meet the needs of the present without compromising the ability of the future generations to meet their own needs.

Maersk Line’s Tripple-E class vessels was recognized as an innovative solution to drive sustainable development by Sustainia100, 100 solutions identified includes solar power in Sudan, sustainable fashion in Switzerland; water-cooling in Canada, solar-cooling in Singapore, buses in Brazil, smart buildings in Sydney.

Quote from Sustania

Commercial shipping is a large contributor of air pollution accounting for 3-4% of man-made CO2 emissions worldwide. Larger ships, optimised for lower speeds and able to carry more cargo, can slash fuel.


!In 2011, Maersk Line secured an order to build 20 container ships bigger than anything currently at sea. The company’s solution, the Triple-E (the “E” is for economy of scale, energy efficiency, and environmentally improved), established a new class of container ship. The capacity of each ship is to be 16% greater than the largest ship built thus far.

The ships are to be outfitted with currently available energy- saving and pollution-control technologies. For instance, the ships’ hulls are optimised for lower speeds. An energy-efficient engine will be supplemented by a waste-heat recovery system that contributes to the ship’s propulsion. The Triple E class will also be equipped with an energy efficient ballast water treatment system, and made ready for eventual installation of a SOx scrubber. A “Cradle to Cradle Passport” ensures that when a Triple E ship reaches retirement its components can be safely disassembled and recycled.
