According to a recent Harvard study, methane emissions could be two to five times higher than the EPA has been reporting.
Colm Sweeney is an atmospheric scientist at CU-Boulder and he co-authored the study.
He spoke to CPR’s Lesley McClurg about why the EPA could be underestimating how much methane is in the air.
THE BOTTOM LINE: If methane is leaking at high levels from oil and gas production then drilling for natural gas isn't greener than coal.
