The world’s top climate scientists calculated in a startling report last year that if we want to limit global warming to 1.5 degrees Celsius this century to avoid devastating social and economic consequences, we need to reach net-zero emissions by 2050.
One big reason that goal is tough to hit is that we’re still heavily dependent on coal, oil, and natural gas — and governments support these forms of energy far more than clean energy.
The International Monetary Fund periodically assesses global subsidies for fossil fuels as part of its work on climate, and it found in a recent working paper that the fossil fuel industry got a whopping $5.2 trillion in subsidies in 2017.
Its last assessment in 2015 tabulated a value of $5.3 trillion — so not much has changed since then, despite growing alarm about rising temperatures and plummeting prices for alternatives like solar and wind energy. And it’s now clearer than ever that the political will to take on fossil fuels still hasn’t materialised.

Clearly, pricing the negative consequences of fossil fuels, especially carbon dioxide, is critical. “If fuel prices had been set at fully efficient levels in 2015, estimated global CO2 emissions would have been 28 percent lower, fossil fuel air pollution deaths 46 percent lower, tax revenues higher by 3.8 percent of global GDP, and net economic benefits (environmental benefits less economic costs) would have amounted to 1.7 percent of global GDP,” according to the IMF report.
