A survey conducted by Stanford University found 1,050 methane leaks in Manhattan, which is equal to about four leaks per mile. Manhattan leaks three to five times more natural gas than cities with newer infrastructure, reports BuzzFeed News

The survey mapped natural gas leaks across the streets of Durham, N.C., Cincinnati, Ohio and Manhattan, N.Y., and identified 132, 351 and 1050 leaks in Durham, Cincinnati and Manhattan, respectively.

Cities with successful pipeline replacement programs have 90 percent fewer leaks per mile than cities without such programs, according to BuzzFeed.

According to the EPA, methane is approximately 25 times more powerful than carbon dioxide.
