Energy efficiency and CO2 emissions
Our total combined energy usage (gas and electricity) has decreased by 5% this year. Our corresponding CO2 emissions for our head offices, distribution centres and stores has reduced for the tenth consecutive year by 7%.
Since 2015, 100% of our energy has come from renewable sources. We reviewed our energy purchasing contracts this year and we continue to source all our UK and ROI electricity from renewable generation.
Building Management Systems
This year we have carried out a Wireless Building Management System (BMS) trial across 4 Topshop stores bringing the total numbers of stores with operating wireless BMS to 8.
We are planning to install wireless BMS into a further 12 Topshop flagship stores by April 2018. This has resulted in an average energy saving of 20% in these stores. All new stores will have wireless BMS and LED lighting as standard.
Distribution Centre energy efficiency
We have made further progress in our goal to deliver energy savings throughout our UK DCs this year.
Our Milton Keynes DC has seen the completion of a project to replace all its lighting with LED lamps. The energy reduction rate is currently 47%.
Meanwhile, our Leeds DC completed a similar project to install more energy-efficient lighting, achieving a 32% reduction in energy consumption.
Cut the Kilowatts (CtK)
Since April 2015 we have been running Cut the Kilowatts (CTK) to engage our retail colleagues in our efforts to reduce energy consumption.
In September 2016 we achieved our aim of rolling out CTK across the entire Topshop chain. Our stores in Ireland joined CTK this year, as we are now able to monitor consumption there for the first time.
Our aim for 2018 is to roll out the campaign to all our remaining brands. Currently, overall savings are running at 5%.
