The Climate Policy and Finance Integrity Project of Transparency International (TI) was a 2.5 million Euro initiative supported by the German Federal Ministry for Nature, Conservancy and Nuclear Safety. It aimed to promote greater transparency, accountability and integrity in decision-making processes and operations of climate financing institutions and mechanisms at global and national levels. Universalia conducted the final evaluation of the project, which was designed for the purposes of learning, to inform future TI work in climate and environment integrity. For the TI Secretariat (TI-S), the National Chapters (NC), the donors and the broad TI movement, this evaluation provided insights on the design of the project, its results, expected as well as unexpected, and their sustainability and scalability. The evaluation team adapted the TI Impact Monitoring approach and undertook data collection through semi-structured interviews with a total of 29 individuals in-person and virtually. Interviewees included the TI-S programme team, NC representatives, staff of multilateral climate finance institutions and select country partners. Additionally, the evaluation team undertook a field mission to the Maldives to participate in a validation meeting with the NCs and to conduct additional interviews and focus group discussions with in-country partners. The evaluation team also undertook an extensive review of project and programme documentation. Deliverables included an inception report, an interim report and a final evaluation report.
