According to a recent IMF Survey Magazine article, Counting the Cost of Energy Subsidies, world-wide energy subsidies in 2015 account for $5.3 trillion or 6.5% of global GDP. The article summarises findings of an IMF working paper (see link below), which provides estimates by country, product (e.g. coal and oil) and component (e.g. global warming, local air pollution and congestion) in an Excel file
The working paper argues that energy subsidies are both larger and more pervasive than previously thought. According to the IMF Survey Magazine:
Eliminating global energy subsidies could reduce deaths related to fossil-fuel emissions by over 50 percent and fossil-fuel related carbon emissions by over 20 percent. The revenue gain from eliminating energy subsidies is projected to be $2.9 trillion (3.6 percent of global GDP) in 2015. This offers huge potential for reducing other taxes or strengthening revenue bases in countries where large informal sector constrains broader fiscal instruments.
In interpreting the findings it is important to understand how the term ‘subsidies’ is being used. 
According to the report, most of the $5.3 trillion “arises from countries setting energy taxes below levels that fully reflect the environmental damage associated with energy consumption.”
In other words, the term subsidy is being used whenever taxes do not fully account for the negative externalities associated with extracting and burning fossil fuels. Perhaps a better term would be ‘under-taxing’ rather than ‘subsidising’. Nevertheless the scale of not internalising externalities is huge. As Lord Nicholas Stern (author of the 2006 Stern Review on the Economics of Climate Change) says:
“The failure to reflect the real costs of fossil fuels in prices and policies means that the lives and livelihoods of billions of people around the world are being threatened by climate change and local air pollution.”
But, while not taxing external costs account for more than 80% of the underpricing of fossil fuel energy, some three-quarters of these external costs relate to local environmental damage, rather than international damage such as global warming. Thus charging for these external costs would benefit primarily the local population, as well as generating revenues, and thus provides a strong argument for governments raising energy prices through increased taxes or reduced subsidies.
So which countries are the major culprits in ‘subsidising’ fossil fuels? What specific measures does the IMF recommend to tackle the problem and what countries are addressing the problem and in what ways? The working paper and articles address these questions.

Questions
- Explain how energy subsidies are defined in the IMF working paper.
- What measurement problems are there in calculating the size of the ‘subsidies’?
- Draw a diagram to show how the under taxing of fossil fuel usage leads to a greater than socially optimum level of consumption of fossil fuels.
- What specific policies are pursued by the four biggest fossil fuel subsidising countries?
- What political problems are there in persuading countries to reduce fossil fuel subsidies/increase fossil fuel taxes.
- Is there a relatively high or low income elasticity of demand for energy? What are the implications of this for different income groups of policies to hold down energy prices?
