This paper presents three case studies of Ukrainian Joint Implementation (JI) projects. The analysis is based on interviews with project stakeholders and public presentations of the case projects. The main questions in focus are: what are the typical JI projects in Ukraine?; what similarities and differences are there between the case projects?; how has the financing of the projects been arranged?; have they been implemented, and how long did it take to launch a project?; and have the same problems or barriers been experienced in all cases?
