Subnational Green Budgeting

OECD Subnational Green Budgeting Guidelines & Toolbox

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.

The Centre for Entrepreneurship, SMEs, Regions, and Cities (CFE) leads the OECD’s work on subnational green budgeting and collaborates with internal and external partners to raise awareness on the topic and disseminate the latest research.

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.

Subnational green budgeting is still in its nascency but there is a rapidly growing interest in the topic. Several regional and local governments across the OECD are experimenting with this approach as a decision-making tool to help align their expenditure and revenue with their green objectives.

The OECD’s Subnational Green Budgeting website includes the latest research on subnational green budgeting, including the Subnational Green Budgeting Toolbox, case studies, and links to other key resources on the topic.

OECD Subnational Green Budgeting Guidelines

The new OECD subnational green budgeting guidelines were developed based on existing subnational green budgeting practices and two green budgeting case studies. Any region or municipality can use these guidelines, and the recommendations that accompany them, to develop their own green budgeting practice or strengthen an existing one.
