- The Northern Sea Route (NSR) along the arctic coast of Russia. This is the maritime route that is likely to be free of ice first and thus represents the highest commercial potential. It would reduce a maritime journey between East Asia and Western Europe from 21,000 km using the Suez Canal to 12,800 km, cutting transit time by 10-15 days. During the Soviet Era, the NSR was used to resupply military and resource extraction along the Soviet Arctic, but this traffic dropped in the early 1990s with the collapse of the Soviet Union. It is only in the late 2000s that interest and traffic picked up. In 2009, two German ships, Beluga Fraternity and Beluga Foresight, completed with a Russian icebreaker escort the first commercial journey across the Northern Sea Route (or Northeast Passage) linking Busan to Rotterdam with several stopovers. However, these trials did not show much commercial potential and most did not resume afterwards.
- The Northwest Passage (NWP) crossing Canada's Arctic Ocean could become usable on a regular basis by 2020, lessening maritime shipping distances substantially. The maritime journey between East Asia and Western Europe would take about 13,600 km using the Northwest Passage, while taking 24,000 km using the Panama Canal. In 2007 the Northwest Passage was open during the summer months for the first time in recorded history, but it remains to be seen how stable this opening is.
- The Transpolar Sea Route (TSR) would use the central part of the Arctic to link the most directly the Strait of Bering and the Atlantic Ocean of Murmansk. This route is at this point hypothetical as it involves ice-free conditions that are not yet observed.
- The Arctic Bridge linking the Russian port of Murmansk or the Norwegian port of Narvik to the Canadian port of Churchill could be used, mostly for the grain trade. Although this is not a trans-Arctic route per se, it is designed to connect two hinterlands (Northwest Europe and the North American Midwest) through the Arctic.
- First, it is uncertain to what extent the receding perennial ice cover is a confirmed trend or simply part of a long term climatic cycle. Even if the Artic routes became regularly open during the summer, the Arctic would still remain closed to commercial navigation during the winter months (unless there are dramatic shifts in weather patterns). As of 2010, the ice free conditions of most Arctic shipping routes were only for about 30 days. Since maritime shipping companies are looking for regular and consistent services, this seasonality has limited commercial appeal.
- Second, there is very limited economic activity around the Arctic Circle, implying that shipping services crossing the Arctic have almost no opportunity to drop and pick-up cargo as they pass through. Thus, unlike other long distance commercial shipping routes there is limited revenue generation potential for shipping lines along the Arctic route, which forbids the emergence of transshipment hubs. Shipping in the arctic is suitable for point to point services linking directly a source port and a destination port. This value proposition could improve if resources (oil and mining) around the Arctic are extracted in greater quantities, which would favor bulk shipping. This would mostly take place along the Siberian coast.
- The Arctic remains a frontier in terms of weather forecast, charting and building a navigation system, implying uncertainties and unreliability for navigation. Substantial efforts have to be made to insure that navigation can take in place in a safe manner along well defined and patrolled navigation routes. The bathymetry in the Arctic is usually shallow, which is limiting the size of the ships that could operated in these waters. Ships also need to be certified to operate in arctic conditions, which increases costs and undermines the economic benefits of the route.
- The setting of rail corridors between China and Europe across Central Asia (the Eurasian landbridge) is offering an option that is more stable and time performing than the Arctic routes.
