'On Equal Terms' is a new checklist developed by UNDP, providing officials, policymakers, and other climate practitioners with a comprehensive guide for establishing a youth-inclusive process for Nationally Determined Contributions (NDCs). This checklist is the result of UNDP's extensive engagement with climate stakeholders, youth organizations, movements, and networks across various countries. Informed by a survey involving 335 youth from 78 countries, aged 15 to 35, the checklist incorporates their perspectives and experiences in participating in NDC formulation, implementation, and monitoring. Adaptable to local contexts, it serves as a guidance tool across six critical stages of the NDC process, from the initial political decision to meaningfully engage youth to NDC implementation.
