World economic growth depends on an active and economically viable international shipping industry.  The International Maritime Organization brings together manufactures, ship owners, flag state, port states and charterers to hammer-out responsible sustainability programs for countries and industry.  The International Maritime Organization (IMO) is the UN voice on maritime issues and shipping.  This web-site provides access to all IMO documents.

Established in 1990, Transport & Environment is the leading NGO voice on smarter and greener transport policies at the EU level in Brussels.
Shipping Emissions Abatement and Trading (SEAat) is a cross-industry, unique, proactive and self-funding group, whose mission is to encourage and facilitate efficient reduction of harmful emissions to air from shipping. SEAaT is an industry group formed in 2002 to raise awareness and acceptance of solutions for emissions reductions that are sustainable, cost effective and achievable.
The Clean Shipping Coalition (CSC) is the only global international environmental organization that focuses exclusively on shipping issues. It promotes policies aimed at the protection and restoration of the marine and atmospheric environment that are consistent with the safe operation of ships, sustainable development, social and economic justice, and human health. The CSC is a non-profit making non-governmental organization that works to improve the environmental performance of international shipping by bringing extensive experience and expertise to bear on relevant international regulatory processes, and in particular the International Maritime Organization (IMO). 
The European Sea Ports Organization was founded in 1993. It represents the port authorities, port associations and port administrations of the seaports of the Member States of the European Union and Norway. ESPO has also observer members in several neighboring countries to the EU.  Ports are essential for European economic growth --  90 % of Europe’s cargo trade in goods passes through the more than 1200 seaports existing in the 22 maritime Member States of the EU and more than 400 million passengers pass through Europe’s ports every year using ferry and cruise services.
