8.2 Transport Mitigation Technologies
Significant achievements have been made in developing transport systems that
reduce GHG emissions though the development of other concerns such as performance
gains, safety, and energy intensity improvementshas been paramount in their
development (IPCC, 1996). A large number of potential GHG emission-reduction
options are technically feasible but only some are economically feasible. Some
are cost-effective but vary among users, resource availability, know-how, institutional
capacity and local market conditions (IPCC, 1996). Energy savings, performance
improvements and reduction in private costs also affect their cost effectiveness.
These options with potential to mitigate GHG emissions can be generally put
into four categories: vehicle technology improvements, including for aircraft
and marine vessels; fuel technology improvements, including alternative fuels;
non-motorised systems; and infrastructure and system changes. Introducing these
options may require justification of other objectives other than GHG mitigation
such as competitiveness, security concerns, and improvement of quality of life
or local environment improvement.
