The Oeko Institute along with T&E has published a report on the integration of maritime transport in the EU emissions trading system (ETS). It looks through the various policy options on the table (the geographical scope, regulated entity, allocation method, use of revenues) as well as examining the compatibility of a shipping ETS with measures currently being discussed at the IMO. The main finding is that the inclusion of shipping in the ETS would not pose any technical barrier of a global emissions reduction measure. Instead, the shipping ETS may accelerate IMO discussions.
