This chapter illustrates some of the outcomes of the pilot project, raises some questions specific to the case study and presents a more general analysis of the potentials and pitfalls of Joint Implementation (JI). Although JI projects could potentially be beneficial to the host countries and locals, they will always create unintended consequences that may have impacts beyond the project site. Thus, national and corporate entities must carefully determine the types of technology to be transferred or projects to be implemented. The chapter also presents some of the practical issues regarding JI, a strategy allowing two or more parties from different countries to jointly reduce greenhouse gas emissions. Adoption of market mechanisms for mitigating climate change is considered to be most economical, but unintended adverse effects as well as such efforts to create successful JI projects may not prove to be so cost-effective.
