Methane isn’t the most ubiquitous of greenhouse gases (that’d be good ‘ol CO2), but it is a potent one: The same amount of methane as CO2 has 20 times the impact in terms of future global warming over a 100-year period. While methane emissions have decreased by 11 percent since 1990, we’re still not in good shape: 50 percent more methane is leaking from oil and gas sites than previously thought and, without action, methane emissions are expected to increase through 2030 -- mostly thanks to fracking. So far the oil and gas industry has balked at the idea of regulating its methane leaks, saying that it might slow production down (we’ve all heard it before, but, man, frack you!).
