Our carbon footprint

Solar panels

Our greenhouse gas (GHG) net emissions in 2016/17 totalled 3.9 million tonnes of CO2e.

We have continued to reduce the carbon intensity of our stores and distribution centres defined as kgCO2e per square foot, and the emissions per case of goods delivered in our distribution network.

Some highlights from our work this year include:

  • Reducing our absolute carbon emissions by 16.7% since 2006/07 using the market-based method for calculating our electricity impacts.
  • Reducing our Group refrigerant emissions by 14% since 2015/16.
  • Investing in energy efficiency programmes that are reducing both our carbon footprint and costs.

We have continued to make progress towards our 2020 property and distribution targets and we are currently exceeding our glide path trajectory towards each of these goals:

2020 Commitment Baseline year Progress to date
Halve the carbon intensity per square foot of our stores and distribution centres 2006/07 -40.6 ◆
25% reduction carbon intensity per case of goods delivered 2011/12 -19.7% ◆

We measure and report our carbon emissions following the Greenhouse Gas Protocol. For more information about how we calculate our carbon footprint, including reporting standards, a more detailed definition of Scope 1, 2 and 3 emissions, and the current emission factors visit our disclosures page.
