I could not agree more with my hon. Friend. The purpose of this inquiry and report is to look at the benefits of producing grass-fed beef and lamb, to keep sustainable grass pasture and to produce very good meat. We would not necessarily want or be able to plough such land, and a huge amount of carbon is captured within the soil. We took some evidence that showed that over years of permanent pasture the carbon actually increases, so there are many good reasons for producing this high-quality beef and lamb.
I will, if I may, continue with my contribution. The footprint of sheep, according to the PAS 2050, is 11.86 kg CO2 equivalent per kilogramme of live weight. The comparative figures for Wales were 7.51 kg CO2 equivalent per kilogramme of live weight and 8.6 kg CO2 equivalent per kilogramme of live weight.
As that has demonstrated, even within a country, there is significant variation in the statistics and no way to determine whether they were driven by different efficiencies or by different ways of producing data. That makes any form of comparative assessment of carbon footprint challenging and poses major difficulties for policy formulation. There is no international consensus on sequestration—the process by which carbon dioxide is removed from the atmosphere by pasture land through a process of absorption and deposition in the soil, which acts as a carbon sink. In essence, that is a natural form of carbon capture and storage.
The importance of including carbon sequestration is highlighted by Mr Bill Grayson, a producer who gave evidence to the inquiry. He ran four models on his farm’s emissions. The PAS 2050 model, which does not include sequestration, concluded that his farm was a net emitter. The other three methods, which include sequestration, put his farm as a net absorber of carbon. Evidently such significant differences make sensible policy development almost impossible.
