As a retail and service organisation, our main impact on the environment is through the buildings we operate and the resources used by staff in their day-to-day work.
We first reported an emissions figure (tonnes of CO2 equivalent (tCO2e)) for the Group in 2012. This includes Scope 1 and Scope 2 emissions, including natural gas consumption, electricity consumption, refrigerant emissions and fuel from company cars.
In 2014, we included our operations in Manila and Australia (Australia electricity consumption was included in 2013). We saw a 4% increase to 59,606.5 tCO2e. Within this, Scope 1 emissions were 3,591.7 tCO2e and Scope 2 emissions were 56,014.9 tCO2e (2013: Scope 1 3,390.0 and Scope 2 54,014.9). However, our overall electricity consumption in kilowatt hours was actually 7% lower in 2014. The difference, therefore, principally relates to an increase in DEFRA greenhouse gas conversion factors from 0.44548 in 2013 to 0.49426 in 2014 for electricity across all regions. Electricity and the UK both account for 95% of our consumption, given the Retail business and the location of our corporate offices. In 2013, we identified an intensity measure – tonnes of CO2 equivalent per £1m of net revenue – to track our performance. In 2014, in spite of the change in conversion rates we saw a year-on-year reduction of 9% from 38.67 tCO2e in 2013 to 35.04 tCO2e in 2014, with 8% growth in Group net revenue in the period offsetting the tCO2e increase. These data were calculated using DEFRA guidelines and conversion rates.
In 2014, we established our Energy Management Forum, bringing together functions from across the business on a quarterly basis to analyse our data, investigate ways in which future greenhouse gas measures can be introduced and identify potential energy saving initiatives around the Group. We reduce waste through recycling and re-use of materials. We also recycle paper, cans and plastic in our offices.
