What Are Nationally Determined Contributions (NDCs) and Why Do They Matter?

This guide explains Nationally Determined Contributions (NDCs) as the primary vehicle for countries to implement the Paris Agreement's goals. It highlights a critical gap between current commitments (leading to 2.6-3.1°C warming) and the 1.5°C target, urging more ambitious 2025 submissions. The document details the need for $4.5 trillion in funding for developing nations and outlines the NCQG's goal to mobilize $300 billion annually by 2035.

• Nationally Determined Contributions (NDCs) are national plans used to reduce greenhouse gas emissions and build resilience to climate impacts, serving as the primary mechanism for countries to meet the Paris Agreement's goals of limiting global warming to "well below" 2 degrees C, and preferably 1.5 degrees C.
• Under the Paris Agreement, countries must submit updated NDCs every five years, with each new submission reflecting their "highest possible ambition." The 2025 cycle is the first since 2020, with targets expected to extend through 2035.
• There is a significant gap between current climate commitments and the goals of the Paris Agreement. NDCs from 2020-2021 put the world on a trajectory for 2.6-2.8 degrees C of warming by 2100, while current policies could lead to a rise as high as 3.1 degrees C by the end of the century.
• Ambitious 2025 NDCs should include five core elements: emissions-reduction targets for 2030 and 2035 (including methane), sector-specific targets for energy and food systems, robust adaptation measures for escalating risks, implementation policies to catalyze investment, and "just transition" principles to ensure fair distribution of benefits.
• Developing countries face a substantial funding gap to implement their NDCs. Of an estimated $4.5 trillion needed cumulatively, $1.5 trillion is tied to "conditional" pledges that require international financial support.
• At COP29, world leaders established the New Collective Quantified Goal (NCQG), agreeing to mobilize $300 billion annually for developing countries' climate action by 2035, with a broader target of $1.3 trillion from all public and private sources in that same year.
• While countries are legally obligated under the Paris Agreement to maintain an NDC and pursue domestic mitigation, they are not legally bound to actually achieve the targets set within those NDCs. However, some nations, including Chile and the United Kingdom, have made their commitments legally binding through national laws.
