Abstract

In Korea, air pollutants such as NOx, SOx, and PM-10 emitted from ships such as cargo ships are calculated and managed by the “Clean Air Policy Support System(CAPSS)”, and various policies are established and managed to reduce emissions from ships.

In particular, five large ports(Busan, Incheon, Ulsan, Yeosu & Gwangyang, Pyeongtaek & Dangjin) have been legally regulated by establishing an “Emission Control Area(ECA)” to regulate the sulfur content in fuel.

Four of these ports(Busan, Incheon, Ulsan, and Yeosu & Gwangyang) have established “Vessel Speed Reduction zones(VSR)” that limit the speed of ships within certain waters, but they are encouraged to participate on a voluntary basis rather than as a mandatory regulation.

Policies to reduce emissions from ships, such as cargo ships, need to be not only formulated and implemented, but also evaluated. This is so that emission reductions can be quantified and verified.

However, the air pollutant emissions of cargo ships managed at the national level do not reflect various operating characteristics, which limits the ability to quantitatively verify the effectiveness of the policy.

Since domestic cargo ships operate within territorial seas, additional consideration must be given to the nature of cargo ships' operations in controlled areas(ECA & VSR).
As for foreign ships, they need to be managed from the point of entry into the country, so it is necessary to set a certain spatial range for them.

In this study, we identify various advanced cases from overseas and mention the need and discussion points to establish "Inventory Zone" for calculating air pollutant emissions from ships in Korea.
