The shale energy boom is fueling a rise in the burning of waste gases, says the World Bank and its Global Gas Flaring Reduction Partnership.
The Wolrd Bank says billions of dollars are lost annually,Reuters reported..
Gas flaring globally rose 4.5 percent in 2011, an amount equal to the annual natural gas use of Denmark, it said.
Its data says the increase is mostly due to the rise of shale oil exploration in North Dakota, an increase that pushed the United States into the Top 10 gas-flaring nations.
Flaring is used to elimate gas at exploration sites and to test production of the well.
The problem is that flaring releases more than 60 pollutants into the air including methane and cancer-causing benzene.
Flaring is permitted but companies could adopt greener or environmentally friendly technologies.
