Climate change, enhanced greenhouse gas emissions and passenger transport - What can we do to make a difference?

The transportation sector, led by the automobile, has been cited constantly as a major contributor through human intervention to climate change. Short of banning car use, file challenge remains one of understanding better what mix of actions might contribute in non-marginal ways to reducing the growth of greenhouse gas emissions and the absolute amount of CO, produced by automobiles. This Paper evaluates instruments aimed at a number of policy objectives linked to efficiency, sustainability and equity, focusing Oil Social Surplus gains in addition to cost effectiveness; but in particular the ability to reduce CO2. TRESIS, an integrated transport, land use and environmental strategy impact simulation program, is used to assess file influence CO2 of a number of 'at source' and 'mitigation' instruments such as improvements in fuel efficiency, a carbon tax, variable user charges, and improvements in public transit. TRESIS is applied to the Sydney metropolitan area with instruments enacted in 2010 up to 2015. (c) 2007 Elsevier Ltd. All rights reserved.
