I think it's huge, because farmers reinvest any money they can save. For example, a friend of mine retrofitted his poultry barn not that long ago, not because of the carbon tax but because he was trying to find more efficiencies. He has made his facility as efficient as possible, but the carbon tax added nearly $60,000 a year in extra costs to his operation. If he had that money to add further value to his livestock facility, think of the savings that would mean and the greenhouse gas emissions reduction in that building alone.
The more we can save, the more we'll invest and improve.
