Leaks and emissions specific to NG aside, NG is primarily a byproduct of the oil extraction industry. It lives in a symbiotic relationship with it. To truly get off oil we need to get off gas as well. There's a reason why oil patch boosters and lobbyists and climate change deniers in places like Alberta are also pushing natural gas; the fortunes of oil and gas are tied together. This is a lobby and sector we need to deprecate not support.
