In climate negotiations, developed countries have pledged to help developing countries in their climate change mitigation and adaptation efforts. Actual climate assistance received is deemed incomplete by recipient countries. The literature indicates that donor countries overestimate the climate change content of their climate aid projects. In this paper, we propose a comprehensive review of bilateral climate aid before focusing on its over-reporting by donor countries. We offer a large set of descriptive statistics based on a previous empirical analysis by Bayramoglu et al. [2022], with the OECD-CRS Database which covers 28 donors, 154 recipients and 63,195 projects from 2002 to 2018.
