The Country Approach to Safeguards Tool (CAST) has been developed as a practical evolution of the UN-REDD Framework for Supporting the Development of Country Approaches to Safeguards. CAST provides countries with an Excel-based, interactive tool to plan and review the development of their approaches to REDD+ safeguards. CAST is designed to be voluntarily applied by REDD+ countries in order to support their planning efforts for activities related to safeguards and SIS, carried out in response to the relevant UNFCCC decisions. CAST includes a comprehensive library of tools and resources relevant to country approaches to safeguards, including both those of UN-REDD as well as those developed by other key programmes and initiatives. CAST may be broadly applied to the full scope of activities related to REDD+ safeguards and SIS in a country, rather than limited to UN-REDD supported activities. Given this, CAST may be used by any REDD+ country, rather than being limited for use by UN-REDD countries.
