Subnational Expenditure Tracking




What is subnational climate-expenditure tracking? 

Subnational climate-expenditure tracking is an essential tool for assessing the financial role of subnational governments in the carbon-neutral transition, in light of global, national, and local climate objectives.

The OECD has developed a pioneering, standardised methodology for tracking climate-related public expenditure and investment in OECD and EU countries. The methodology was initially developed in 2018 as part of an OECD pilot project and is based on the National Accounts database, a unique repository of internationally comparable expenditure and investment data. In 2020, the OECD and European Commission teamed up to further refine this methodology, including by linking it to the EU Taxonomy.

The Subnational Government Climate Finance Database was a key output of this project and includes subnational government climate-related expenditure and investment data for 33 OECD and EU countries for the period 2001-2019.

Subnational Government Climate Finance Database 


The new Subnational Government Climate Finance Database was developed in 2022 as part of a joint OECD-European Commission project that aimed to enhance the tracking, measurement, and mobilisation of subnational government climate finance. 

 Data was collected using a standardised methodology, initially developed in 2018 by the OECD and updated as part of the joint OECD-EC project, based on National Accounts data. The database covers subnational government climate-significant expenditure and investment for 33 OECD and EU countries from 2001 to 2019.

Subnational Government Climate Expenditure and Revenue Tracking in OECD and EU Countries

Monitoring progress towards meeting the Paris Agreement requires improving the tracking and measurement of public climate expenditure, investment, and revenues. This OECD working paper was prepared as part of the joint OECD-European Commission project on “Financing Climate Action in Regions and Cities”. It presents a pilot methodology for tracking, measuring, and comparing subnational government climate-significant expenditure and investment in OECD and EU countries based on National Accounts data. It also includes an analysis of the data collected, which is available in the new OECD Subnational Government Climate Finance database, and a stocktake of existing climate finance tracking initiatives. On the revenue side, the paper presents an analysis of climate-related public revenue sources available to subnational governments in OECD and EU countries, the results of which are available in the new online Compendium of Financial Instruments that Support Subnational Climate Action.
