The international Carbon Footprint Protocol is a complicated business – but a vital one. It calculates the annual carbon emissions of a company, graded against three different levels. ‘Scope three’ demands the highest standards, and is the one used by Wedderwill. Everything is audited, including: Used fossil fuels, Used electricity, Used fertilizers, Air miles travelled, Car hire usage, Delivery to FOB, shops, restaurants and other clients. The only exclusion is emissions created by the production of dry goods – such as labels, bottles and corks – produced by third parties.
