This paper describes research on the impacts of alternative policies aimed at reducing the greenhouse gas emissions produced by freight transport in urban areas. A combined travel demand, traffic network and pollutant emissions modelling system was established, to test the impacts of the following generic policy initiatives: ‘best practice’ truck fleet fuel efficiency, general reductions in peak period traffic congestion, improved traffic management, provision of real-time traffic information, infrastructure improvements, changes to industrial land use distribution, and improved vehicle load factors. The Sydney region was use as a case study. Whilst almost all of the policy options showed the potential for some improvement in emissions outcomes, the best option overall was that directed at vehicle load factors. The policy direction aimed at changing the distribution of industrial land use provided mixed results, which suggested that complementary measures to influence modal choice for certain urban freight tasks were also required to achieve positive outcomes for this policy initiative.
