The exact worth of massive global fossil fuel subsidies is incredibly hard to figure. There’s no real consistency in the definitions of subsidies, or how they should be calculated. As a result, estimates of global subsidy support for fossil fuels vary widely.
According to a new analysis by the Worldwatch Institute, these estimates range from $523 billion to over $1.9 trillion, depending on what is considered a “subsidy” and how exactly they are tallied.
Worldwatch Institute research fellow Philipp Tagwerker, who authored the brief, explains:
The lack of a clear definition of “subsidy” makes it hard to compare the different methods used to value support for fossil fuels, but the varying approaches nevertheless illustrate global trends. Fossil fuel subsidies declined in 2009, increased in 2010, and then in 2011 reached almost the same level as in 2008. The decrease in subsidies was due almost entirely to fluctuations in fuel prices rather than to policy changes.
In other words, though the estimates vary widely, they all agree that fossil fuel subsidies are back up to the record levels they were at in 2008, before the financial crisis caused a temporary dip. So while world leaders, including President Obama, talk about ending subsidies that benefit one of the world's richest industries, there hasn't been any actual reduction.
