This isn't exactly something we're proud to put on our resume. Methane gas emission in the U.S. is millions of tons higher than the Environmental Protection Administration estimates, according to a new study in Proceedings of the National Academy of Science. In 2008, the study found the U.S. spewed 49 million tons of methane into the air—compared to the 32 million tons the EPA estimates or the 29 million tons determined by the European Commission. The scientific research showed much of the global warming-causing gas is coming from Texas, Oklahoma, and Kansas.
