Well, if it's all being sold for consumption, it would be net zero carbon change for the product itself plus whatever carbon it takes to drive production.

The main advantage is the reducing the reliance on beef.

Though I gotta wonder how much demand can go down before the price reduction makes producing the volume of beef no longer worth it and only profitable if it's scaled down because until then, they'll just lower prices to keep producing the same amount or more because you're a failure if line doesn't go up.
