This study evaluates the progress of fossil-fuel subsidy reform in Ukraine since its launch in 2016 using the OECD “bottom-up”, inventory, approach. It also identifies major subsidy schemes that need significant reform. The report reflects the energy subsidy policies and reforms in Ukraine prior to Russia’s full-scale invasion in February 2022. The analysis covers: budgetary transfers, government revenue foregone (or tax expenditure), induced transfers in the form of cross-subsidies or below market tariffs and transfer of risk to government. The study also covers fossil-fuels subsidies to production and consumption, particularly, for natural gas, coal and electricity generated from fossil fuels while support for energy efficiency and renewables is considered for comparative purposes. This report also briefly discusses the taxation and energy pricing policies in Ukraine that have had direct or indirect impact on the evolution of fossil-fuel subsidies in the country. Detailed estimates of all individual support measures are provided in the Annexes to the report.
