I buy carbon offsets to try to blunt my impact but I'd also pay a premium for more sustainable milk (and more importantly cheese) that was harder to distinguish. Carbon offsetting is a poor substitute for just not having a big carbon footprint to begin with. It's a sticking plaster at best, and incredibly hard to verify the impact of as an individual consumer.
