Walkers – Carbon Trust partnership

Walkers carbon savings

Working with the Carbon Trust

We're delighted to be working with the Carbon Trust - an independent organisation set up by the Government to accelerate the move to a low carbon economy by working with organisations to reduce carbon emissions.

We have been involved since its very beginnings in 2001 and Walkers were amongst the first to sign up to the Carbon Reduction Label initiative in 2007, which aims to help businesses reduce their environmental impact and help consumers make more environmentally friendly decisions.

Over the last 2 years we have reduced our Walkers carbon footprint by 7% - which is an overall saving of 4,800 tonnes of CO2 compared to our 2007 footprint. On a standard bag of Walkers Crisps the saving is equal to 6g of CO2. This reduction means that Walkers Crisps is the first product to retain the Carbon Reduction Label and are as committed as ever to making future improvements.

How we saved 4,800 tonnes of CO2

Achieving such an outstanding result was a team effort. We worked closely with Walkers staff and our suppliers to make our 7% reduction. We did it by:

  • Only using British potatoes, to cut down food miles

  • Improving production efficiencyi to reduce gas by 11%, electricity by 22%ii and water consumption by over 700 million litres in our Leicester factory alone.

  • Making a 4.5% reduction in emissions associated with producing crisp packets

  • Recycling over 90% of our waste

  • Reducing the weight of our packaging

  • Running delivery lorries on biodiesel and using fuel efficient driving

This is just the beginning

Our recent carbon emission reductions have saved us an estimated £400,000iii, but we're not in it for the money. Climate change is one of the greatest challenges the world faces today. That's why we're reinvesting the money we've saved into more environmental initiatives, for example hosting Sustainability Summits with suppliers.

"We're delighted that Walkers is the first company to retain the use of the Carbon Trust's Carbon Reduction Label, as consumers have told us that they welcome the Label and the commitment it represents. The 7% reduction is a joint achievement with our suppliers and Walkers will be building on this achievement as part of PepsiCo UK's wider commitment to reduce energy consumption by 20% by 2011." .

The pie chart below shows the breakdown of the 7% reduction we've made so far:

Part of this was due to production line efficiencies but a big part was due to moving production to a more efficient line.
41% of the 6g carbon reduction was due to gas and 37% was due to electricity. The relative reductions from 07 to 09 are 11% for gas and 22% for electricity.
This is the savings achieved by the 7% reduction in carbon footprint. Each footprint is based on one full year of data so this savings figure relates the manufacturing energy spend in the 09 carbon footprint to the energy spend in the 07 carbon footprint.
