UN Climate Change News, 11 November 2025 - Climate action by non-Party stakeholders - such as cities, regions, businesses and civil society - is a key driver for the implementation of the first global stocktake (GST) outcome. This is one of the key findings of the 2025 Yearbook of Global Climate Action, published by UN Climate Change today, which also introduces a set of indicators to track future progress.
"This ninth edition demonstrates that the Global Climate Action Agenda has matured from a platform for mobilization into an instrument for implementation," write UN Climate Change Executive Secretary Simon Stiell in the Yearbook's foreword. "It provides evidence that systems transformation is underway, and highlights where momentum must now accelerate."
The 2025 Yearbook comes at a pivotal moment for climate action, 10 years after the adoption of the Paris Agreement, and as we enter a new era which the Executive Secretary has said must focus on bringing the COP process together with the real economy, to accelerate implementation.
This is crucial at all levels, and involving all parts of societies and economies, to "spread the vast benefits of climate action to billions more people," as he told the Bloomberg Philanthropies & COP30 Local Climate Action Summit in Rio de Janeiro just prior COP30, focused on sub-national climate actions.
