This paper provides a comprehensive global, regional, and country-level update of: (i) efficient fossil fuel prices to reflect their full private and social costs; and (ii) subsidies implied by mispricing fuels. The methodology improves over previous IMF analyses through more sophisticated estimation of costs and impacts of reform. Globally, fossil fuel subsidies were $5.9 trillion in 2020 or about 6.8 percent of GDP, and are expected to rise to 7.4 percent of GDP in 2025. Just 8 percent of the 2020 subsidy reflects undercharging for supply costs (explicit subsidies) and 92 percent for undercharging for environmental costs and foregone consumption taxes (implicit subsidies). Efficient fuel pricing in 2025 would reduce global carbon dioxide emissions 36 percent below baseline levels, which is in line with keeping global warming to 1.5 degrees, while raising revenues worth 3.8 percent of global GDP and preventing 0.9 million local air pollution deaths. Accompanying spreadsheets provide detailed results for 191 countries.

This paper updates estimates of fossil fuel subsidies, defined as fuel consumption times the gap between existing and efficient prices (i.e., prices warranted by supply costs, environmental costs, and revenue considerations), for 191 countries. Globally, subsidies remained large at $4.7 trillion (6.3 percent of global GDP) in 2015 and are projected at $5.2 trillion (6.5 percent of GDP) in 2017. The largest subsidizers in 2015 were China ($1.4 trillion), United States ($649 billion), Russia ($551 billion), European Union ($289 billion), and India ($209 billion). About three quarters of global subsidies are due to domestic factors—energy pricing reform thus remains largely in countries’ own national interest—while coal and petroleum together account for 85 percent of global subsidies. Efficient fossil fuel pricing in 2015 would have lowered global carbon emissions by 28 percent and fossil fuel air pollution deaths by 46 percent, and increased government revenue by 3.8 percent of GDP.

Energy subsidies are aimed at protecting consumers, however, subsidies aggravate fiscal imbalances, crowd out priority public spending, and depress private investment, including in the energy sector. This book provides the most comprehensive estimates of energy subsidies currently available for 176 countries and an analysis of “how to do” energy subsidy reform, drawing on insights from 22 country case studies undertaken by the IMF staff and analyses carried out by other institutions.

This paper provides a comprehensive global, regional, and country-level update of: (i) efficient fossil fuel prices to reflect supply and environmental costs; and (ii) subsidies implied by charging below efficient fuel prices. Globally, fossil fuel subsidies were $7 trillion in 2022 or 7.1 percent of GDP. Explicit subsidies (undercharging for supply costs) have more than doubled since 2020 but are still only 18 percent of the total subsidy, while nearly 60 percent is due to undercharging for global warming and local air pollution. Differences between efficient prices and retail fuel prices are large and pervasive, for example, 80 percent of global coal consumption was priced at below half of its efficient level in 2022. Full fossil fuel price reform would reduce global carbon dioxide emissions to an estimated 43 percent below baseline levels in 2030 (in line with keeping global warming to 1.5-2oC), while raising revenues worth 3.6 percent of global GDP and preventing 1.6 million local air pollution deaths per year. Accompanying spreadsheets provide detailed results for 170 countries.

This report presents research on fossil fuel subsidy reform across 20 countries and reveals an average reduction in national GHG emissions of 11% by 2020 from potential reform, and savings of USD 93 per tonne of CO2. With modest recycling of resources to renewables and energy efficiency, reductions can be improved. Countries are including reforms in contributions towards a climate agreement.

Energy taxes can produce substantial environmental and revenue benefits and are an important component of countries’ fiscal systems. Although the principle that these taxes should reflect global warming, air pollution, road congestion, and other adverse environmental impacts of energy use is well established, there has been little previous work providing guidance on how countries can put this principle into practice. This book develops a practical methodology, and associated tools, to show how the major environmental damages from energy can be quantified for different countries and used to design the efficient set of energy taxes.

Government price subsidies are pervasive in developed, emerging, and low-income countries. A subsidy is a form of government intervention resulting in a deviation of an actual price facing consumers and producers from a specified benchmark price. Subsidies affect consumption and production patterns as well as the distribution of resources, with important implications for the budget, expenditure composition, and long-term growth. They can and often do involve fiscal costs, but not all affect government fiscal accounts in the same way. Price subsidies have spillover effects onto prices and quantities in domestic, regional, or global markets. This paper discusses the key issues and policy options in the reform of subsidies for fossil fuels and selected food commodities, and their implications for the work of the Fund.
