A major new resource providing the most comprehensive record of how net zero commitments have evolved over time has been published by the Net Zero Tracker, to which the Blavatnik School contributes. 

The dataset covers net zero commitments made by countries, states and regions, cities, and companies, and tracks these commitments over time back to the 2015 Paris Agreement, the international treaty on climate change. 

It represents a significant new resource for researchers, policymakers, investors and practitioners seeking to understand how climate commitments have diffused, and how their credibility, transparency and integrity have changed over time. 

It covers more than 4,000 entities and tracks around 90 indicators relating to targets, emissions coverage, governance, removals and carbon credits across the period 2015–2026. 

Building on the work behind Thomas Hale, Jessica Green and Aldrick Arceo's ‘Net Zero Wave’ paper (2024), the new dataset makes longitudinal analysis available at much greater scale. 

More broadly, the dataset provides the ability to test one of the central questions in climate governance: how targets can reinforce each other and interact with policy, markets, technology deployment and public support in the ways needed to drive global decarbonisation.
