The Working Group III (WGIII) contribution to the Intergovernmental Panel on Climate Change (IPCC) 6^th Assessment Report (AR6) provides an updated global assessment of climate change mitigation progress and pledges, and examines the sources of global emissions. It explains developments in emission reduction and mitigation efforts, assessing the impact of national climate pledges in relation to long-term emissions goals.

Fully aligned with the scope of the IPCC Working Group III, PARIS REINFORCE has developed an integrated assessment modelling framework for effectively supporting the design and evaluation of climate mitigation policies, globally and in Europe, with respect to the objectives of the Paris Agreement. This framework is oriented towards enhancing the legitimacy of the scientific processes in support of climate policymaking, by co-creating the modelling exercises and improving the transparency of models, methods, and tools. It also develops novel methods and tailored processes for better-informed models and improved robustness of results against different types of climate and model-related uncertainties.

Based on this integrative scientific paradigm, PARIS REINFORCE has produced over 60 scientific publications (available here), reporting and disseminating project outputs, as well as directly underpinning the majority of WG III chapters, with a focus on mitigation pathways, energy systems, innovation and its transfer, and broader sustainable development. Notably, the project has carried out several model inter-comparison exercises, directly feeding in the WG III scenarios database (see Annex III - Scenarios and Modelling Methods), with emphasis on trajectories accurately reflecting current policies and Nationally Determined Contributions (NDCs).
