'Super Emitters' Responsible for Most US Methane Emissions

The bulk of methane emissions in the United States can be traced to a small number of "super emitting" natural gas wells [phys.org], according to a new study.

"We're finding that when it comes to natural gas leaks, a 50/5 rule applies: That is, the largest 5 percent of leaks are typically responsible for more than 50 percent of the total volume of leakage," said study co-author Adam Brandt, an assistant professor of energy resources engineering at Stanford's School of Earth, Energy & Environmental Sciences.

The findings, published online in the journal Environmental Science & Technology, could lead to more efficient strategies for sampling emissions and fixing the most significant leaks, said Brandt, who is also a senior fellow at Stanford's Precourt Institute for Energy. By focusing on finding and fixing the biggest emitters, companies can significantly reduce the amount of methane leaking into the atmosphere.

Thank goodness the answer wasn't "cows."
