I agree that carbon footprint should be something that people keep in mind when they're eating. What's worth noting though is that regenerative agriculture (where the goal is to be sustainable and can be carbon net negative) requires ruminant grazing as part of the integrative crop production cycle.

A recently commissioned LCA study done by Quantis showed that for White Oak Pastures, estimated carbon footprint was -3.5kg CO2e/kg (vs 30+ for conventional beef): http://blog.whiteoakpastures.com/blog/carbon-negative-grassf...

This seems to jibe well with the research coming out of the Rodale Institute and peer review (I've written previously about this so instead of rewriting, I'll just link: https://news.ycombinator.com/item?id=20652657).

WOP sells 1 lb of their ground beef for $10/lb (either a 90/10 or 80/20 blend), so it's about twice as expensive as conventional beef: https://www.bls.gov/regions/mid-atlantic/data/averageretailf... (you could probably match the price if you are able to buy and store in bulk from a local regenerative-practice farm), but I think for most people reading this comment, the price difference is still de minimis compared to their overall daily cost/expenditure.

Another thing to keep in mind is the latest and most detailed FAO put full LCA (this includes supply chain, etc) of CO2e of global livestock production at 14.5%: http://www.fao.org/news/story/en/item/197623/icode/

IMO the anti-beef climate story seems to be very overblown/disproportionate compared to its relative GHG impact (lets not distracted, switching off of fossil fuels is by far the priority).
