The whole point of a MAC curve is to show the investments people could make that give the best returns. I do not quite see the logic of dismissing the MAC curve and saying this is automatically good value for money. We need to see the metrics. Our last presentation said it was all about metrics. We need to see what carbon credits, or whatever one likes to call them, this delivers, verified within the Teagasc MAC curve so that we can see that this is a better investment of €40 million than on other elements within the curve, such as anaerobic digestion and genetics. There are 29 items in that curve. The MAC curve was developed to guide policymakers on choices.
