We have undertaken an annual greenhouse gas emissions (GHG) footprinting exercise since 2012.

This has provided insight into where the largest climate impacts are and enabled us to better prioritise resources. Emissions are stated in tonnes of CO2 equivalent (TCO2e) and data has been verified by environmental consultancy Trucost to AA1000 Assurance Standard.

We aim to continually improve the transparency of our GHG data with an emphasis on increasing the range of ‘Scope 3’ indirect emissions that we publish, this year including emissions from business travel for the first time.

GHG emissions reductions in financial year 2018 demonstrated good progress:

  • Absolute direct Group GHG emissions declined by 6% year on year to 9,384 TCO2e despite business growth
  • Group GHG emission intensity (emissions per £million of revenue) showed a year on year decrease of 19%.
  • A reduction in air freight of product from supplier factories resulted in a reduction in transport emissions of 9,179 tonnes.

A detailed breakdown of our emissions for financial year 2018 are available below:

GHG emission methodology

We have reported on all of the emission sources required under the Companies Act 2006 (Strategic Report and Directors’ Reports) Regulations 2013. We report our emissions data using a financial control approach meaning we include emissions from all parts of the business where we have the ability to direct financial and operating policies — this includes our owned and operated Retail stores and office space. Data has been prepared in accordance with the WRI/WBCSD GHG Protocol Corporate Accounting and Reporting Standard (revised edition), WRI/WBCSD GHG Protocol Scope 2 Guidance 2015 and emission factors from the DECC/DEFRA GHG Conversion Factors for Company Reporting 2016.

In addition, the guidance on the reporting of ‘Scope 2’ emissions allows us to demonstrate the reduced environmental impact of purchasing renewable electricity. This ‘market based method’ shows the emissions created using the precise mix of generating technologies used to supply our estate rather than simply taking a ‘grid average’ of all generating technologies as is the case under the location based method. We can now report zero GHG emissions from the market based method as 100% of our electricity is from renewable sources.

Although we strive to ensure that our emission figures are accurate, access to the relevant data is not always possible and, therefore, some estimation is necessary. 12% of our emissions this year are based on estimated data.

The below graph demonstrates our improvement in emissions intensity over time:
