The International Monetary Fund (IMF) released its estimate of global fossil fuel subsidies for 2015 at $5.3 trillion—almost ten times higher than the International Energy Agency’s (IEA) calculation of $548 billion for 2013.(i] The difference is not the change of a 2-year span, but the methodology. The IEA uses a “price-gap” methodology, which is the difference between end-use prices and supply costs that include shipping costs, margins, and value-added taxes. In other words, the agency calculates subsidies that the governments pay their own citizens to enable them to buy energy more cheaply than the market price.
