it would be wrong to justify such investment as a solution to climate change.

in the environmental context as it constitutes the only transport segment where
aircraft, trains, coaches and cars naturally compete for market shares.
link that connects two major cities located 500 km apart. It assumes that emissions
from new vehicles and aircraft in 2025 can be used as a proxy for the emissions
during a 50 year investment depreciation period. The emissions from the marginal
production of electricity, used by rail and electric vehicles, are estimated to
amount on average to 530 gram per kWh for the entire period. Fuels used by road
vehicles are assumed to be on average 80 percent fossil and 20 per cent renewable

from long-distance coaches, and 30 per cent from pre-existing trains. The remaining
25 per cent is new generated traffic. Under these assumptions would the investment

one-way trips. Assuming 10 million single journeys per year, the total reduction

would amount to $3.6 million, which is very little in the context of high speed
rail. The sensitivity analysis shows that alternative assumptions do not significantly
change the outcome. One may also have to consider the impact on climate change
from building the new line. Construction emissions for a line of this length may
amount to several million tons of CO2
grounds so long as the carbon gains made in traffic balances the emissions caused
during construction. However, marketing high speed rail as a part of the solution
to climate change is clearly wrong. Investment in infrastructure for modal shift
should only be considered when traffic volumes are high enough to carry the cost.
The principal benefits of high speed rail are time savings, additional capacity
and generated traffic, not a reduction of greenhouse gases.
