This policy compendium was prepared by the Energy Technology Policy (ETP) Division of the Directorate of Sustainability, Technology and Outlooks (STO) of the International Energy Agency (IEA). The study was designed and directed by Simon Bennett under the guidance of Timur Gül, IEA Chief Energy Technology Officer. Araceli Fernandez Pales, Head of the Technology Innovation Unit, provided strategic guidance. Akari Nagai provided research and analytical inputs. It benefits from the work of the IEA collaborators on policy data at Mission Innovation and the OECD (OECD-IEA-ITF STI policies for net zero database).

We are grateful to all delegates of the G20 Research and Innovation Working Group who conceived the project and provided guidance and support throughout, including by reviewing early drafts and contributing additional policies to be highlighted.

Michael Keenan, Jessican Amblier and Carolina Resendehaddad of the Organisation for Economic Cooperation and Devekllopment (OECD) contributed the box on the Agenda for Transformative STI Policies. Thanks also to Curtis Brainard, Poeli Bojorquez, Astrid Dumond, Jethro Mullen and Wonjik Yang of the IEA Communications and Digital Office. Liv Gaunt and Lizzie Sayer edited the manuscript and Jon Custer designed the web interface.
