Open government is a powerful catalyst for driving democracy, public trust, and inclusive growth. In recognition of the growing demand by OECD Members to acknowledge and promote this role, the OECD Council adopted the Recommendation on Open Government in 2017. To date, it remains the first and only internationally recognised legal instrument on open government and has guided many countries in the design and implementation of their open government agendas. In 2020/2021, the OECD carried out a survey on the implementation of the Recommendation among all countries that adhered to it and other partner countries, with further data collected through a Perception Survey with delegates to the OECD Working Party on Open Government. Drawing on the insights gathered from these two surveys, and at the request of the OECD Council, this report takes stock of the implementation of the Recommendation, its dissemination, and its ongoing significance.
