An exclusive economic zone (EEZ) is a sea zone prescribed by the United Nations Convention on the Law of the Sea over which a state has special rights regarding the exploration and use of marine resources, including energy production from water and wind. It stretches from the baseline out to 200 nautical miles (nmi) from its coast. In colloquial usage, the term may include the continental shelf. The term does not include either the territorial sea or the continental shelf beyond the 200 nmi limit. The difference between the territorial sea and the exclusive economic zone is that the first confers full sovereignty over the waters, whereas the second is merely a "sovereign right" which refers to the coastal state's rights below the surface of the sea. The surface waters, as can be seen in the map, are international waters.

Within the MSP Challenge Game the EEZ indicates the Planning Region of a team. Planning outside of your team's EEZ requires the team who's border is crossed to approve the plan before implementation.
This layer is a combination of 2 sources:
Flanders Marine Institute (2012): Intersect of IHO Sea Areas and Exclusive Economic Zones.
HELCOM (2019): Exclusive Economic Zone.
Flanders Marine Institute (2012): Combination of the information on regional seas and national maritime boundaries.
HELCOM (2019): "The dataset contains the digitized Exclusive Economic Zone (EEZ) boundaries in the Baltic Sea based on the documents submitted by the Baltic Sea countries to the United Nations. These submissions, which are available online (http://www.un.org/depts/los/LEGISLATIONANDTREATIES/europe.htm), include nautical charts, maritime boundary delimitation agreements, and treaties between different countries (containing the agreed coordinates of the boundaries). In case of non-existing submission, the older EEZ version was used resulting from various HELCOM activities. The dataset has been amended with bilateral agreements, when available."

The layer from Flanders Marine Institute (2012) was clipped to the extend of the Baltic Sea and Kattegat, (as defined by IHO, retrieved on 2017-05-22; geometry error and duplicates were fixed; and its geometry was simplified to implement the layer in the MSP Challenge. The layer was updated on 2020-11-30 using the new version of the Exclusive Economic Zone of HELCOM (2019). The base layer is the one from Flanders Marine Institute (2012), the polygons were edited to match the boundaries of HELCOM (2019).
