Exclusive Economic Zone

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.

Generally, a state's exclusive economic zone is an area beyond and adjacent to the territorial sea, extending seaward to a distance of no more than 200 nautical miles (370 km) out from its coastal baseline. The exception to this rule occurs when exclusive economic zones would overlap; that is, state coastal baselines are less than 400 nautical miles (740 km) apart. When an overlap occurs, it is up to the states to delineate the actual maritime boundary. Generally, any point within an overlapping area defaults to the nearest state.

A state's exclusive economic zone starts at the seaward edge of its territorial sea and extends outward to a distance of 200 nautical miles (370.4 km) from the baseline. The exclusive economic zone stretches much further into sea than the territorial waters, which end at 12 nmi (22 km) from the coastal baseline (if following the rules set out in the UN Convention on the Law of the Sea). Thus, the exclusive economic zones includes the contiguous zone. States also have rights to the seabed of what is called the continental shelf up to 350 nautical miles (648 km) from the coastal baseline, beyond the exclusive economic zones, but such areas are not part of their exclusive economic zones. The legal definition of the continental shelf does not directly correspond to the geological meaning of the term, as it also includes the continental rise and slope, and the entire seabed within the exclusive economic zone.
