Mr. John Spink:

On anaerobic digestion, AD, Mr. Callanan mentioned that we were starting some work. For biogas or electricity from AD to be classed as a renewable fuel, it has to meet certain sustainability criteria. One of those is a 70% reduction in energy costs compared with the alternative. That is work we are starting now, looking at how we can sustainably produce effectively from grassland feedstocks that will meet the sustainability criteria. If we do not meet them, it is not really worth investing in AD in the first place. In terms of the rewetted peatlands and paludiculture, I am not aware of any research we are doing in that area currently.
