Flaring Gas: How Not to Waste a Valuable Resource

Every year, oil fields around the globe burn, or “flare,” an estimated 3.5 percent of the world’s natural gas supply. The gas is produced alongside oil and must be disposed of during the production process. Eliminating flaring would reduce CO2 emissions by as much as removing 77 million cars from the road. Moreover, the flaring wastes a valuable non-renewable energy resource.
