I'm not an expert here, but I see what you're saying. Is the carbon calculation from the meat _processing_??? Every year I hunt a buck and carry it off the mountain. So the carbon footprint for getting that meat for my family is really the drive up to and from wherever I'm hunting from, plus a few other small things that probably amount to almost nothing.

I live close to a large meat processing facility, and it appears to be quite an energy intensive operation from the outside. Never been inside though, so I can't say for sure. But transporting live cattle, feed, water, slaughter, freeze, freeze+transport all might be pretty carbon heavy.

All of that would go away with renewable energy and therefore reducing meat consumption would not be "the next frontier" in the battle against climate change as the original poster said.
