> Surely chicken in your backyard can be kept without CO2 impacts with some effort.

I’m not sure this is possible, at least not in a typical yard or urban garden. According to one study[1] community gardens in and around cities emit six times the CO2 per serving compared to industrial agriculture. I assume this is roughly applicable to backyard gardens too. I wouldn’t be surprised if this isn’t applicable to livestock—which the study appears to have excluded—but also wouldn’t be surprised if the story is similar with chickens/livestock.

I imagine that even if it is less efficient to grow your chickens in the back yard, it might be possible to approach or exceed current industrial poultry farms in CO2 efficiency. My hunch is that if those farms get incentivized by penalties on CO2 production it would be impossible though.

I said backyard, not some urban garden.

Does that seem likely to make a difference? The study covered individual gardens as well. The low-tech gardening practices they mention sound exactly like backyard gardens.

Of course. The whole study is about cities, even the first sentences already make this very clear. It has nothing to do with normal gardens, nothing _at all_.

I may have missed the part in the paper which explains why a backyard garden is dramatically different in efficiency if said backyard is in a city versus the suburbs. Could you clarify or point me to the thing you’re referring to?
