According to the World Bank, over 7,500,000 kt of [[Glossary:Methane|methane]] were released into the atmosphere worldwide as a result of agriculture and industry. The United States government is developing regulations to reduce methane emissions from the oil industry by more than 40% over the next decade. Methane emissions are second only to carbon dioxide as contributors to the greenhouse effect. At the same time, the government is investing money in research to seek reliable ways to measure the level of methane emissions in the atmosphere that have come directly from natural gas production.

Recent estimates for methane emissions from natural gas industries in the United States have been widely divergent. Some discrepancies noted by industry surveys have led to a thorough review of newly available information and are leading to the improvement of estimation methods and emission factors associated with activities that comprise natural-gas systems. This has manifested itself in the engineering estimations that are used for compiling the national GHG Emissions Inventory and in the methods used by companies for reporting under the mandatory national GHG Reporting Program. Both the inventory and the reporting program are programs of the US Environmental Protection Agency (EPA).

Using direct measures of emissions from devices on 377 wells operated by 10 companies cooperating on the survey, Allen gathered data that reshaped the EPA’s pie chart of E&P emissions of methane. The study concluded that emissions during flowback have sharply dropped from 26% in the EPA’s Greenhouse Gas Inventory to 1%. That decline, plus larger-than-expected emissions by gas-powered pneumatic control devices, pushed its share of the natural gas emissions from the EPA estimate of 26% to 42%, making it the largest single category.

The United States government is developing regulations to reduce methane emissions from the oil industry by more than 40% over the next decade. At the same time, the government is investing money in research to seek reliable ways to measure the level of methane emissions in the atmosphere that have come directly from natural gas production.
