Comprising over 20 practical tools, the ICAT Toolbox addresses critical areas such as policy impact assessment, NDC tracking, data management, climate finance transparency, and just transitions. These tools are tailored to meet the needs of developing countries, providing step-by-step guidance and methodologies to build robust transparency frameworks. For instance, the Transformational Change Toolkit helps evaluate the potential for systemic shifts towards low-carbon development, while the Climate Finance Transparency Guide assists in tracking and reporting climate finance flows.
By offering these resources, the ICAT Toolbox enables countries to strengthen their climate policies, enhance accountability, and foster international trust, ultimately contributing to more effective and equitable climate action.

All ICAT Tools and Guides
Organized into eight core areas, the ICAT Toolbox offers a comprehensive, end-to-end approach to support countries in achieving their climate goals effectively and transparently.
ICAT's policy impact assessment tools and guides offer a robust, open-source framework designed for countries and stakeholders to evaluate the real-world effects of climate policies. By furnishing policymakers with clear, data-driven insights into both the benefits and costs of climate interventions, the toolkit empowers countries to maximize positive impacts while addressing potential trade-offs —including sustainable development and transformational change.
