This is a story about natural gas leakage, and we’re not talking about what happens after your grandfather says, “Pull my finger!”
Recent reports in journals such as Science and the Proceedings of the National Academy of Sciences have carried some depressing news: Natural gas, the “bridge fuel” touted by President Obama for its lower CO2 emissions and domestic abundance, may not actually be better for the climate than coal. Natural gas is mostly methane, which is half as carbon intensive as coal when it's burned, but when it's released directly into the atmosphere, it's 86 times worse for the climate than CO2 over a 20-year time frame. Rampant methane leakage in the fracking process and from pipelines raises natural gas’s total greenhouse gas emissions; the studies estimate that more than 2 percent of gas in the U.S. may escape through leaks.
It doesn’t have to be this way. The technology already exists to dramatically reduce methane leakage for a reasonable price. Environmental groups have put out reports outlining how. They could serve as a template for the oil and gas industry to follow voluntarily, or for the EPA to require under the Clean Air Act.
