EmissionSEA – Extrapolation of emissions from ships

Global climate goals, stricter emission regulations, and noticeable cost pressure are leading to ever greater incentives to reduce ship emissions and increase the energy efficiency of shipping. In particular, the EU reporting regulation on CO2 emissions from, to, and within the European Union, which has been in force since 01.01.2018, has led to an increase in the energy efficiency of shipping. The specification of CO2 emissions is mandatory. However, there are currently no sufficiently suitable methods to validate reported emissions, since the ships are operating worldwide and the routes are recalculated due to adverse weather conditions, projections such as those for road traffic cannot be implemented.

The aim is to develop a methodology for the quantitative determination of CO2 emissions from shipping. With the help of data from the Automatic Identification System (AIS), movement information is set in relation to ship size, speed, and meteorological and oceanographic environmental conditions. More than 500,000,000 daily AIS data records from hundreds of own and thousands of cooperative AIS base stations as well as detailed ship data including information on the main propulsion plant are available to JCS and form the data basis for the project. Data on fuel consumption and emissions are not publicly available and represent the gap to be closed.
