How has the Paris Agreement shaped mitigation policy? Assessing progress at ten years

Online | Nov 17, 2025 | 2:00 PM – 3:30 PM

As the Paris Agreement marks its 10th anniversary, this session organized by OECD (opening remarks by Walid Oueslati, Head of Climate, Biodiversity and Water Division, and moderation by Elisa Lanzi, Senior Economist, Climate Mitigation, OECD) explores its impact on climate change mitigation action and policies.   

Drawing on insights from a novel global OECD survey of policymakers and non-governmental experts, this session will highlight how the Agreement has shaped national mitigation policies, the barriers that continue to hinder implementation and the policy priorities moving forward. 

Henri Waisman, Director of the Deep Decarbonization Pathways programme, IDDRI, will present the 2025 DDP report: A Decade of National Climate Action: Stocktake And The Road Ahead.

The OECD will present key findings from the survey, presented in the recently published report “The Paris Agreement at Ten Years: Expert Views on Progress and Challenges for Climate Change Mitigation”. A panel of experts and stakeholders will then reflect on progress made, remaining gaps and next steps to highlight how climate action can evolve to meet the urgency of the climate crisis.
