This new web format for Country Notes on Fossil Fuel Support provides interactive on-line access to the latest data from the OECD Inventory of Support Measures for Fossil Fuels by country – identifying and estimating the value of support arising from policies that encourage the production or consumption of fossil fuels. The web version allows users to download, share and play with the data. Interactive graphics enable data visualisation, in national currency, by beneficiary and by energy product. These Country Notes provide, for each of the 50 economies covered in the Inventory, a snapshot of energy market structure, the current state of energy prices and taxes, and recent developments and trends in fossil fuel support. Data and country notes for the EU Eastern Partnership (EaP) countries have been collected and prepared as part of the GREEN Action Task Force.
