emissions from hydraulically fractured well completions at U.S.
natural gas production sites are 97 percent lower than
Environmental Protection Agency national emissions estimates
for 2011, according to the results of a University of Texas
This is due to
emissions reduction equipment in place at the majority of the
190 U.S. production sites sampled during the study that helped
reduce methane emissions by 99 percent.
Erica Bowman, vice
president of research and policy analysis for Americas
Natural Gas Alliance, said her organization is reviewing the
study but "we welcome the finding that overall methane
emissions from the production of natural gas are lower than the
most recent EPA estimates. The study provides further support
for the findings of other credible researchersthat
greater use of natural gas can substantially reduce greenhouse
