Assuming there is a law. I think we can already detect methane well enough to know that cows make a lot of it.

You don't want to make the law something they must "escape" from, but rather something they can profit from by not polluting. Like tax credits.

I disagree. I think we need to increasingly shift to pollution taxes because 1) physical pollution is hard to hide and 2) minimising pollution both improves the environment and maximises industrial efficiency.

This new result could push things along, because it provides the solution without lowering production. There would be less lobbying and backlash against such measures if the industry has clear way of dealing with them.
