The same kind and volume of methane that is captured in coal-bed methane wells. So, for example, if a coal-bed methane well leaks, even at the ridiculous 15% value, that's still a potential 85% reduction in emissions from that same coal bed being mined.

I understand that there may be some waste in the production of natural gas, but don't for a minute think that this seepage is in any way comparable to the volume of methane involved in open pit coal mining, or mountain top removal, or even deep shaft mining.
