Working papers in Transport Economics
Vad skulle likabehandling av alla transportslag innebära för kustsjöfarten, miljön och behovet av infrastrukturinvesteringar?
Abstract: The cost of short-sea shipping on the seas surrounding
Sweden will increase considerably after 2015 as a result of the
introduction of stringent emission limits on NOx and sulphur. This may give
trucks and trains an upper hand in market segments where customers can
choose between sea transport and land-based modes. This report shows that
the balance would shift in favor of shipping if government gives all modes
an equal liability for external costs. With the internalization based on
the short-term social marginal costs of infrastructure use, accident risk,
and emissions of NOx, sulphur and CO2, rail will be losing market shares.
In this scenario the current fairway dues would have to be lowered by at
least 90 per cent in order to reflect the short-term marginal cost (rather
than variable + fixed costs), while at the same time railway infrastructure
charges would quadruple. A surprising result of the calculations is that
long-distance freight transport by truck on the main road arteries that
compete with short-sea shipping will by 2015 have internalized its
short-term social marginal costs based on the current (2011) taxation of
vehicles, roads and fuels. This is a result of an increasingly cleaner
vehicle fleet and the use of the best roads whose social marginal costs for
accidents and road tear are well below average. Equal treatment of all
modes with regard to social cost liability will make it possible for
short-sea shipping to relieve the national railway system of some of its
growing capacity problems that would otherwise have to be resolved by
substantial investment in additional rail infrastructure.
