Governments are at an inflection point in addressing climate change. While climate action has gained momentum over the past decade, current efforts are not sufficient to keep the Paris Agreement’s goals within reach. This OECD-UNDP report shows accelerated climate action is not only economically feasible but also drives sustainable development and protects long-term prosperity. With the 2025 update of Nationally Determined Contributions (NDCs), this evidence-based report offers insights into how aligning climate action with broader national priorities can deliver widespread benefits – from poverty reduction and better health to increased energy access and green investment opportunities. Aimed at policymakers from environment, finance, economic and development ministries, as well as investors and businesses, the report demonstrates how “Enhanced NDCs” can attract finance, unlock innovation and ensure a just transition that supports vulnerable communities.
