The goal of this manual is to support the integration of gender equality in climate change interventions and climate finance to enhance the efficacy of climate change mitigation and adaptation interventions and ensure that gender co-benefits are obtained. It is intended for use by climate change project proponents from governments, international and national direct access entities, and civil society organizations. It reviews the GCF Gender Policy which stipulates that resource allocation for adaptation and mitigation projects and programs contribute to gender equality and women’s empowerment, as well as related programming provisions including readiness support. It covers gender mainstreaming tools and methodological approaches which can be employed in designing a broad range projects, including gender analysis, gender assessment and action plans, gender-responsive results or logical frameworks, project implementation and monitoring and evaluation (M&E). The manual focuses on the minimum set of tools needed to meet the core requirements of the GCF project cycle.
