The International Energy Agency (IEA) made headlines recently by concluding that fossil fuels received far more global subsidies than renewable energy in 2010. However, it appears that the IEA survey only included data from the countries with the largest fossil fuel subsidies, which are mainly developing countries whose economies largely depend on fossil fuel production. National Geographic’s The Great Energy Challenge also includes fossil fuel subsidy data from developed countries (Figure 1), bringing the total global value close to $500 billion for 2010....
Global CO2 emissions from fossil fuels in 2011 totalled 31.6 billion tons. Given the SCC range of $5 to $68 per ton of CO2, those emissions correspond to a cost of $158 billion to $2.1 trillion per year, globally – roughly $23 to $300 per person.
