FTA: “Federal tax subsidies to the oil and gas industry alone cost US taxpayers at least US$2 billion each year,” write researchers from the Stockholm Environment Institute and Earth Track in a recent Nature Energy article. That $2 billion in uncollected taxes is helping some oil fields go from "unprofitable" to "profitable," increasing the amount of oil that's available for consumption. (The researchers broadly used the term "subsidies" to indicate different types of tax-based support that "confer a financial benefit from government to oil producer.")
