As nations prepare to unveil ambitious new NDCs in 2025, WRI is developing research and detailed guidance informed by current climate science, the outcomes of the first-ever Global Stocktake and the latest in systems trends. Delve into our collection of resources focused on sectoral opportunities and financing mechanisms for the next round of NDCs.

    State of Climate Action 2025

    The State of Climate Action 2025 provides the most comprehensive roadmap yet for closing the global gap in climate action to help keep the Paris Agreement goal within reach, as well as grades collective efforts to combat the climate crisis across key sectors. It finds that recent progress toward 1.5°C-aligned targets has largely failed to materialize at the required pace and scale and highlights where action must accelerate this decade to reduce greenhouse gas emissions, scale up carbon removal and increase climate finance.

    Stronger NDCs With Cities, States, and Regions: Recommendations for National Governments

    Countries can significantly enhance the ambition of their Nationally Determined Contributions (NDCs) through a more collaborative and integrated approach with subnational governments to fully align with the Paris Agreement goals. This document supports national governments in the facilitation of input from subnational governments in the NDC development process.

    State of Climate Action 2023

    The State of Climate Action 2023 provides the world’s most comprehensive roadmap of how to close the gap in climate action across sectors to limit global warming to 1.5°C. It finds that recent progress toward 1.5°C-aligned targets isn’t happening at the pace and scale necessary and highlights where action must urgently accelerate this decade to reduce greenhouse gas emissions, scale up carbon removal and increase climate finance.

    Elements for the First Global Stocktake Outcome

    This expert note presents suggestions for how the Global Stocktake at COP28 can deliver transformational action to keep the global goal of limiting temperature rise to 1.5 degrees C alive and address the impacts of climate change.

    Expert Note September 8, 2023

Estimating how much it will cost to implement an NDC – and calculating the costs of not doing so — is the first step to making strategic decisions about which financial instruments and policies are needed. The Paying for Paris Resource Hub provides a central knowledge base where governments can begin exploring the diverse range of instruments available to help finance their climate goals.
