Has IMO addressed climate change?

IMO is heavily engaged in the fight to protect and preserve our environment - both marine and atmospheric - and is energetically pursuing the limitation and reduction of greenhouse gas emissions from shipping operations. IMO has adopted measures to reduce air pollution form ships as well as energy efficiency measures including the Energy Efficiency Design Index, which is mandatory for new ships, and the requirement for a Ship Energy Efficiency Management Plan, for all ships.
