The 2015 Climate Change Agreement of Paris did not include the shipping industry. However, due to political pressure, IMO took already in September 2015 initial steps to develop a legal framework for improving CO²-emissions of existing vessels.

The scenario is that ships should report a set of parameters (fuel consumption and distance), which will pave the way to calculating the actual emissions caused by the merchant fleet. It will reinforce the determination by the shipping industry to make the necessary efforts in order to help keep global warming under the 2°C-limit.

In EU, a European Directive (approved on 29/04/2015 and to enter into force on 1/1/2018) on monitoring, reporting and verifying CO2-emissions from maritime transport (i.e. all vessels calling at an EU port) provides the legal background for such reporting scheme. Most of the work will be based on the so-called Energy Efficiency Operational Indicator (EEOI), a rather complex issue , as it is based on vessels’ technical efficiency (design, engines, hull shape etc.), transport operations (loading ratio) and speed.

Further negotiations are needed to harmonize the EU-implementation with the IMO system.
