I am somewhat optimistic due to i) political momentum around methane (e.g. Global Methane Pledge), ii) annual IEA methane tracker and iii) emission thresholds for hydrogen formulated in terms of "lifecycle GHG" (often tbd but e.g. IRA seems to include upstream methane through the 45VH2-GREET model).

Indeed these issues are being discussed broadly, though that does not necessarily mean that final regulation will be effective. Details matter, and interested industries will fight hard (see US 45V debate), so it will be crucial that policymakers have good analysis like this one!
