Dr. David Wilson:

Deputy Carthy asked about grassland. Yes, this is new to us. It is something we have not engaged in here. The Germans and Dutch have been working on it but they came at it from a different point. Their sites were extraordinarily high greenhouse gas emitters because of the amount of nutrients and fertilisers that had gone into them before they were rewetted. They were very high emitters so there was an impetus to rewet. The benefits from rewetting in Germany and the Netherlands were very high because the emissions were so high beforehand.
