The fact is that this was a conscious choice, even recently. The switch to natural gas that everyone is touting is one that is designed to cause higher short-term emissions.
Methane is really bad over a 20-year time frame and only really lets natural gas equal coal over a 100-year period (assuming typical fugitive emissions rates). The transition from coal to natural gas is accelerating the rate at which we boil ourselves alive.
Oh it does for sure. At least in Canada there are government regulations requiring inspections by 3rd parties to check for leaks with some sort of thermal camera. I'm not familiar with the technology to check for leaks but I've had to fix the leaks before and it's taken seriously and well documented.
