According to the IPCC Sixth Assessment Report (2022), for planned adaptation interventions to be successful in leading to societally desirable outcomes, they need to be feasible, have the potential to be effective in reducing climate risks and impacts, and be able to do so in a manner that is aligned with the principles of justice. Planned interventions that do not have these attributes are unlikely to be effective in achieving their adaptation aims or lead to outcomes that are societally acceptable; regardless of how well implemented they are. The ICAT Assessment Tool for Adaptation Project Proposals is an excel-based assessment tool developed to support organizations that finance climate change adaptation projects to assess project proposals to identify whether they are “well-placed” to realise societally desirable adaptation outcomes. The tool is accompanied by a document, Fostering Successful Adaptation Projects, to guide users through the mechanics of the tool.
