3. Summary
Arctic sea ice is in rapid decline, and this may open up new opportunities
for economic activity. This paper describes a scenario for future shipping
activity and emissions in the Arctic, specifically related to transpolar
container shipping and petroleum extraction. The future Arctic transit
shipping activity level and the resulting emissions have been modelled by
jointly assessing the volume of global seaborne trade and the attractiveness
of selecting the Arctic transit route rather than traditional sea routes (e.g.
via Suez). Future shipping activity and emissions related to petroleum
extraction have been estimated based on projected production data.
The results show that part-year arctic transit may be economically attractive
for container traffic from North Asia between 2030 and 2050. With a
projected Arctic trade potential of 1.4 million TEU in 2030, this amounts
to a total of about 480 transit voyages across the Arctic in the summer of
2030. For 2050, the Arctic trade potential rises to 2.5 million TEU and the
total number of Arctic transit passages (one-way) in the summer of 2050
is about 850.
Due to shorter travel time and the need for a smaller fleet to carry the
same amount of cargo between Asia and Europe by going across the Arctic
compared with the route via the Suez Canal, CO2 emissions are reduced
by 1.2 Mt annually in 2030 and by 2.9 Mt annually in 2050.

ports. If the Arctic route from a given port is favourable
in economic terms, the model determines the number of
passages and resulting emissions based on the projected
cargo volume to be transported and the selected ship
concept (i.e. cargo capacity and sailing season).
Future shipping activity and emissions related to petroleum
extraction have been estimated based on projected
production data provided by ArcAct project partners.
The emissions from tanker vessels have been modelled by
constructing shipping routes and locating transhipment
ports based on the production data. For supply vessels,
a simplified statistical approach is used to correlate the
amount of fuel consumed with the amount of petroleum
extracted.
This paper is divided into nine sections. Section 2
discusses the challenges associated with operations in the
Arctic under the current ice and metocean conditions,
Section 3 reviews shipping activities in the Arctic,
and Section 4 outlines a future ice scenario. Section 5
presents the model, with assumptions and input data, and
compares the results for the most economically favourable
shipping scenario with other studies. Section 6 indicates
possible future shipping activity associated with oil and
gas activities. Challenges associated with the expected
increase of activity in the Arctic regions are summarised
in Section 7. Conclusions are provided in Section 8 and
recommendations in Section 9.

low air and sea temperatures. These were reviewed in the summer, have spurred speculations that the Arctic Ocean

• Icing from sea spray, precipitation, and fog, which
raise both stability problems and other safety issues.
• Polar lows (small storms that are difficult to
detect and predict).
• Wind chill, i.e. combinations of low temperatures
and strong winds, which is a safety and health issue.

parts of the Arctic with seasonal or all-year ice cover is poor. (Perovich et al. (2009) with March 2010 added)
Sea ice in the Arctic has shown dramatic changes over
the last 30 years, (see Figure 1; updated from Perovich
et. al., 2009). The extent of summer ice (September) has,
on average, declined by roughly 9 % per decade between
1979 and 2009, and the extent of winter ice (March) by 2.5
% per decade. September 2007 had the smallest ice extent
on record. Ice thickness has also decreased considerably
in the last three to four decades. Based on sonar data from
submarines for 1975 – 2000 and satellite data from 2004
– 2008, Perovich et al. (2009) estimated a reduction of
mean winter sea ice thickness from 3.4 m in 1975 to 1.9
m in 2008 (via a maximum of 3.6 m in 1980), caused by
decreasing amounts of old and thick ice.

shipping activity was dominated by community re-supply,
fishing, and tourism. There is also export from a few large
mining operations in Alaska (zinc) and Russia (mainly
nickel but also other minerals), according to Glomsrød
and Aslaksen (2006, 2009) and Ocean Futures (OF, 2010).
Figure 2, from PAME (2000), shows the main traffic routes
used by commercial ships in the Arctic. Note that some
icebreakers and submarines have also visited the North
Pole.
Community re-supply is taking place along the NSR and
NWP. Fishing mainly takes place in the ice-free waters
around Iceland and in the Bering, Barents, and Norwegian
Seas, and tourism is at its greatest intensity along the coasts
of Northern Norway, Southwest Greenland, and Svalbard

Commercial transit traffic, except tourism, has taken place
only along the NSR, which was opened to foreign ships in
1991. The transit traffic peaked in 1993, when, according
to Ragner (2000) and Brigham and Ellis (2004), more
than 200 000 tonnes of cargo were carried by Russian ships
between Asia and Europe. This fell to zero in 1997, and
remained at that level for the rest of the century (Ragner,

The decrease in ice thickness is expected to continue in
summer as well as in winter, due to reduced amounts of
multi-year ice.
In addition to the modelled changes in ice cover and ice
thickness, it is believed that the actual ice properties, along
with iceberg occurrence rates and metocean conditions,
could change in the Arctic as consequences of global
warming.

Emission reductions may also result in reduced costs,
assuming that future external damage costs caused by
ship emissions are internalized (e.g. by introduction of tax
regime or quota market).
In the following section, the developed model (Nilssen
et al., in preparation) is outlined, along with the input
data applied, and the assumptions made to estimate the
future Asia-Europe Arctic transit shipping activity and the
resulting emissions in 2030 and 2050.
The model calculates the costs of a selected Arctic sea
route versus the Suez Canal route, enabling a comparison
of the alternatives. Costs are calculated by utilizing
detailed projected ice data, by modelling speed and fuel
consumption of ships in ice, and by adding additional
costs from building and operating ships suitable for Arctic
operation (e.g. ice class). The comparison is made for
routes originating in different Asian ports. If the Arctic
route from a given port is favourable in economic terms,
the model estimates the number of passages and emissions
based on the projected amount of cargo to be transported Figure 4. Arctic transit routes used in the Arctic transit shipping analysis.

the Manhattan through the NWP in 1969 (e.g. Gedney and
Helfferich, 1983), traffic through NWP is not considered
plausible. This is because the navigation channels suitable
for large ships are likely to continue to have difficult ice
conditions for many years ahead (Transport Canada, 2005;
Wilson et al., 2004), making the route unreliable with
respect to transit time, and therefore less attractive to the
shipping industry than the eastern alternatives.

voyages across the Arctic in the summer of 2030. For 2050,
the total trade potential rises to 5.6 million TEU for the
Tokyo hub, with 2.5 million TEU estimated for the Arctic,
giving about 850 Arctic transit passages (one-way) in the
summer of 2050. The predicted amount of containers
that will be transported through the Arctic corresponds to
about 8 % of the total container trade between Asia and
Europe in 2030, and about 10 % in 2050. The numbers
of passages were then used to calculate fuel consumption
and ship emissions.
Figure 6 shows the estimated annual fuel consumption by
the fleet of container ships along Route 3 in 2030. The
fuel consumption is converted to emissions using emission
factors. For CO2 this gives emissions in the Arctic of 3.7 Mt
in 2030 and 5.6 Mt in 2050.
Due to shorter travel time, fewer ships are needed to carry
the same amount of cargo between Asia and Europe by
going across the Arctic compared with the route via the

from transit traffic in 2050.

20. Recommendations
Improved model and input data will be needed to provide
a more complete picture of possible scenarios for shipping
and oil and gas activities in the Arctic. Examples are
models that consider the whole logistics chain, including
ice management, as well as weather and ice routing, and
better and more detailed regional data on sea ice and
metocean parameters.
It has been argued that increased activity in the Arctic
will result in challenges related to the environment and
safety that will need to be addressed. These challenges
appear solvable, provided that the regulators take action
and implement the necessary safeguards, making Arctic
shipping not only economically sound, but also socially
and environmentally acceptable, and hence a viable
option for the future.
As part of such action, work on Arctic impact and risk
assessments should be strengthened and intensified. The
assessments should not be limited to shipping and oil and
gas developments, but could also include fisheries, tourism,
and extraction of other natural resources. They must
include design and operational requirements with respect
to safety and environment for all future activities in the
Arctic, ways to reduce impacts from the various activities
and improve their sustainability, as well as infrastructure
aspects like satellite communication, search and rescue,
weather forecasts, and spill prevention and contingency
approaches.
There appears to be a need for more binding regulatory
and governance regimes in the Arctic. Some of the
framework already exits. Making the IMO guidelines for
ships operating in polar waters mandatory could be a good
start.
