Slap a "No Cow Farts" sticker/logo on beef raised with a sufficient level of seaweed in their diet. Choose that instead of farty-beef at the store.

Don't expect anything to work as well as individuals changing their minds about what is important and acting on it.

Thats crazy, that depends entirely on people being able to afford to pay more for the same basic product. What economics would indicate that this would happen?

You can get antibiotic free meat from whole foods etc, but what do you think is consumed at higher quantities?

If its purely up to buyers choice, it will not happen unless there is a cost associated with carbon output.

Lot's of people pay extra for "organic", "grass-fed", "cage-free", "fair trade", "kosher" and other certifications on products now. "Organic" has just about taken over the produce section in my supermarket in the last few years. And "USDA organic" has dubious value for a lot of products.

If you observe that people don't often pay for "antibiotic free" meat it's likely because they don't see it as a worthwhile value proposition.

If you say that buyers won't choose to pay for global-warming-safe beef, while watching them choose to pay for chemical-pesticide-free beef then that is just another way of saying that no one cares about global warming, and I don't think that is the case.
