Just how bad is fossil “natural” gas? And, as it turns out, the infrastructure used to produce, store, distribute, transmit, and burn gas leaks like a sieve , making gas as bad as coal for the climate. Gas plants and infrastructure emit nitrogen oxides (NOx) during combustion, which degrade local air quality.
