I think everyone has "always" known that methane is not a key driver of climate change. Its relatively short atmospheric life and relatively low concentration make it have a modest effect relative to CO2, even if it is more potent.

A 30% reduction serves to further show that the priority needs to be CO2 in general, and everything but the low hanging fruit for methane emissions is a distraction.

Of course, the possibility of runaway effects and short term positive feedback loops from methane release from permafrost, etc, is still a concern. I guess a 30% reduction there is somewhat good news.
