Methane is an inert gas that is odorless. When you "smell" methane you smell an additive from the gas industry. Methane leaking from gas wells does not have a smell nor is it in your neighborhood. The largest source of methane emissions is natural wetlands and agriculture. https://twitter.com/SenMarkey/status/1387132899418324995

Nearly 3 times more methane is released from natural sources and agriculture than from oil, gas, and coal combined. Methane represents 0.000001875% of the atmosphere and has a negligible impact on total warming since 1850.

These policies aren't about better environmental policy. If they were I'd be for them. The true intent is to increase costs to the oil and gas industry to make energy from those sources more expensive and subsidizing wind and solar making them cheaper. This is cronyism in action.
