In less than a decade PepsiCo would like its UK operations to be fossil fuel free. To achieve this the company is working closely with its supply chain where most of its environmental impact is generated.
It started with one of its biggest brands: Walkers crisps, looking at how the potatoes are grown, packaging and transported. It has introduced low carbon fertilisers and modernised its transport fleet. The company has cut the carbon footprint of a packet of Walker's crisps by more than 9%.
PepsiCo built a diagnostic tool to identify opportunities to boost efficiency. Sustainability managers have been appointed to champion the company's internal "resource conservation" programme.
Multi-use trailers are used these days to collect potatoes from farms as well as to deliver boxes of crisps.
