Old coal mines can emit methane for a long time if not remediated. Many have been long abandoned or if there is a currently active owner they aren't able to cover the cost because they aren't viable. It will fall to government to do anything about it.

Same as with nuclear, you privatise the profit and socialise the losses. Nuclear and coal would have made way to newer forms of energy long ago if not for that imho.

Not saying that there haven't been and still are lots of subsidies for wind, solar and hydro, but it's obscene how much money has been given to the big players in "traditional" forms of energy creation.
