Due to direct benefit to herders, this is easier to reinforce than methane reductions with supplement e.g. seaweed as has been posted here before, since those benefits are not captured (without a carbon market or climate-friendly consumer branding to command a premium). Even if beef was methane-free, it would still have a larger impact than chicken (without regenerative agriculture, silviculture etc) but projections show that consumption is going to grow steadily as the global middle class grows so adopting these efficiencies will be important.
