ABSTRACT
The basis of this project has been to carry out detailed assessments of real-life pilot joint-implementation (JI) projects. The aims of these assessments have been rather wide ranging – a consequence of the varying objectives which motivate JI. In this chapter, the authors set out what they believe to be the best available methodology to account for the emission reductions achieved by JI projects and the associated economic costs. In fact, they define four critical accounting variables which are suitable for this task. Project-level assessments of the case study projects have been carried out using a spreadsheet model of each JI project. In order to calculate the emissions reduction associated with a JI project, one must first find the total emissions of both the baseline and the JI options. The incremental costs – necessary for the economic assessment – will, of course, be calculated using a counterfactual baseline.
