Pessimistic as I am, the combination will be fees that are cheaper than fixing the problems as well as passing that extra cost on to the consumers. It's better than nothing, but I usually find that phrase used when a lot more could have been done but wasn't because it was good enough to quieten some of the noise.

I forgot another possibility - lawyers and lobbyists to neuter any actual teeth the law ends up having.

Also, I have to put out the reminder since the "80x CO2 greenhouse effect" was used - that half life average (still used by many including the IPCC) isn't all that valid if methane emissions continue to rise. It gets worse as methane breakdown/methane addition ups the total amount at any given time.
