Doesn't matter from a CO2 point of view. Sheep are better than cattle in this regard, but you still have to transport sheep, feed them crops in the winter, and so on. The net CO2 cost is still high. You're better off from an efficiency point of view in using that energy to grow more vegetables. We could probably grow forests for the carbon capture on most Welsh hillsides where sheep are grazed.
