We see partnership as part of the way we do business and we also have a great relationship with our milk farmers in England. We use fresh milk in our chocolate and there's a combine of farmers who supply only milk that makes our UK chocolate. We've been co-operating with them on their carbon footprint, so that's the measurement that measures how much carbon is produced to make milk. And we found in our Cadbury Dairy Milk bars that 70 per cent of the carbon footprint comes from milk. So, by working with this co-operative, we've begun to help them and help us make some changes in our supply chain. So that includes different types of animal food, it includes investment, so that the lorry that brings the animal feed only comes once rather than three times, and actually helping them really make some changes on their farms, so it's more efficient.
