Control mechanisms for Nordic ship emissions

image of Control mechanisms for Nordic ship emissions

Shipping today operates under a complex set of international and domestic regulations. However, the environmental regulations have lagged behind those of other industries. This situation is now changing quite dramatically. The increased focus on environmental issues, combined with the growing realisation of the actual pollution burden imposed by shipping, has led to an upsurge in both international and national regulations. Some are ready and will enter into force in the near future, while others are still being developed. On behalf of the Nordic Council of Ministers DNV has carried out a study on possible control mechanisms for Nordic ship emission. The aim is to assess the baseline shipping emissions and reduction potential and the possible controlling mechanisms (both incentives and regulations) available for reducing the emissions to air from shipping within the Nordic region.



Nordic ship traffic and emissions

Automatic Identification System (AIS) is an international aid to prevent ship collisions and identify and monitor ships. AIS is made mandatory to vessels over 300 GT on international voyages and 500 BT in domestic trade, and all tankers and passenger ships irrespective of size. Exempt from the requirement to be equipped with AIS are special categories such as warship, naval auxiliary and government-owned or governmentoperated vessels and small craft and leisure boats. Still, a large proportion of the vessels not required to carry a transponder still have them for safety reasons. Hence, we consider the selection of vessels in our dataset to give a good representation of the actual fleet.
