The cost and effectiveness of policies to reduce vehicle emissions

Transport sector policies already contribute to moderating greenhouse gas emissions from road vehicles. They are increasingly designed to contribute to overall societal targets to mitigate climate change. While abatement costs in transport are relatively high, there are plausible arguments in favor of further abatement in this sector. The empirical basis to decide upon combinations of fuel economy standards and fuel taxes, however, remains weak. This publication investigates the effectiveness and costs of various mitigation options in road transport, and discusses the distribution of abatement efforts across sectors of the economy.--Publisher's description.
