The Environmental Law Institute surveyed existing AIJ projects under the United States Initiative on Joint Implementation (USIJI) and AIJ projects initiated from other countries. The survey looked for evidence of transparent mechanisms and public involvement in decision-making. In addition, ELI examined development projects analogous to the AIJ framework, such as multilateral development bank investments and environmental fund investments, that included participatory elements. Although the primary geographical focus of the study was Latin America, ELI surveyed projects in Asia and Europe as well. Concurrent with this general overview, ELI's cooperation with the non-governmental Corporación Latinoamericana para el Desarrollo (CLD) on the process of developing a national JI program in Ecuador informed and supported this report.
