It might make more CO2 on average, considering the higher energy requirements to transport and store LNG, and direct leaks/flaring of CH4 is a hot greenhouse gas. But burning natural gas also doesn’t dump out gigatons of toxic coal ash that completely destroys any water table in the vicinity, empty sulfur and heavy metals and radioactivity into the atmosphere, cause acid rain…

No fossil fuel is perfect but natural gas burns so goddamn clean, its a lot fucking better than a 1700’s level coal fuel source
