IMHO, This is entirely within the scope of the industry itself to fix. Fund an international governing body that can have animal welfare standards, certify them, and market them to the policymakers as an alternative. This will only work if the process is transparent, though - otherwise the calls of corporate greenwashing will come.
These sorts of successes came with the sorts of certifications you see from the FSC, Certified humane, and other bodies. The key is to actually focus on what’s best for the animals, make it clear that’s the point, and involve the NGO’s.
