Subnational Green Budgeting


Better aligning regional and local budgets with green objectives 

The Paris Collaborative on Green Budgeting, established in 2017 with the OECD serving as the Secretariat, aims to design new, innovative tools for national and subnational governments to better align national expenditure and revenue processes with climate and other environmental goals.    

Green budgeting is a priority-based budgeting approach that uses the tools of budgetary policymaking to help governments at all levels achieve environmental and climate objectives. Examples of green budgeting tools include green impact assessments, green budget tagging, applying a green lens to expenditure reviews, and environmental fiscal reform, among others. Several regional and local governments across the OECD are experimenting this approach as a decision-making tool to help align their expenditure and revenue with their green objectives. Our work includes Subnational Green Budgeting Guidelines, a self-assessment tool and case studies.

Subnational Green Budgeting Guidelines

Self-assessment Tool


In order to help regions and cities overcome the challenges of developing and implementing a green budgeting approach, the OECD has developed a set of six key guidelines. Subnational governments of all sizes and types can use these guidelines to launch their own green budgeting practice or strengthen an existing one.



The guidelines are complemented by a self-assessment tool that all regions and cities can use to identify their strengths and potential gaps for starting a green budgeting practice or improving an existing one.

The report also provides strategic recommendations to support Andalusia to improve environmental outcomes and enhance national and global environmental performance.
