Our sustainability team works with colleagues across our supply chain, suppliers and co-manufacturers to calculate carbon emissions released at each stage of a product's lifecycle. We then go the extra mile and have partnered with the Carbon Trust since 2012 to analyse and certify our work on product carbon foot printing. The Carbon Trust is an independent, expert third-party partner of leading organisations around the world, helping them contribute to and benefit from a more sustainable future. You can find out more about them on their website .
