The Kyoto Protocol created two mechanisms through which greenhouse gas emission reductions from specific projects around the world could earn credits: Joint Implementation (JI) and the Clean Development Mechanism (CDM). In order to ascertain the tons of greenhouse gas emissions that a project avoids, reduces or sequesters, it is necessary to have a baseline that estimates what the emissions would have been in the absence of the project. Baseline development for potential projects to reduce emissions from stationary sources has been and continues to be examined by a number of organisations, including the IEA. There is little other published work on the topic of mobile source baselines for CDM and JI projects. This report is a first attempt to explore the issues surrounding estimation of greenhouse gas emission baselines for potential JI and CDM projects in the transport sector. As such, the scope of this report is kept broad, leaving the field open for future research and discussion.
