Russia has delayed its plan to reduce gas flaring to 5 percent within three years to 2014, Natural Resources Minister Yury Trutnev announced on Thursday
Flaring gas, found when extracting oil and considered too difficult and expensive to get to the market, sends tons of the greenhouse gas carbon dioxide into the atmosphere.
Both the Energy and Natural Resources ministries have decided to postpone the target date, Trutnev told reporters, declining to name a reason for the delay.
Some experts say Russia, the world's biggest gas exporter, is also the leading flarer of gas, but by its own calculations it is only the second-largest after Nigeria.
For some, a fear of government-proposed fines combined with the commercial prospect of selling the gas encouraged firms to establish vigorous programs to curb gas flaring.
The country's largest oil producer and biggest flarer, Rosneft, will spend 67 billion rubles ($2.74 billion) over the next five years on gas utilization.
Gazprom Neft has said it will invest 17.6 billion rubles ($714.6 million) in cutting gas flaring in 2008 to 2010.
Russia burns off 38 billion cubic meters of gas a year, a World Bank study said. The government has set a goal of using 95 percent of associated gas by 2011.
Currently, the country flares about 45 percent of the gas it produces at oil fields, the World Bank said in its report.
