This report provides an overview of green budgeting practices across OECD countries based on the 2022 OECD Green Budgeting Survey, as well as the index methodology for the Survey. It takes stock of OECD countries’ progress in bringing climate and environmental considerations into budgeting frameworks and processes. Green budgeting involves a systematic approach across all stages of the budget process, including financial reporting and budget oversight. The growth in green budgeting in OECD countries, as shown in the report, demonstrates the key role of budget offices in ensuring that policy priorities relating to climate change and the environment are taken into account when allocating resources through the budget process.
