Managing our impact on the environment
We are committed to making real progress, implementing practical measures where possible to mitigate our impact, reduce global warming and to protect our habitat and natural resources.
New dual function site
In June 2016, we combined our previous sites in High Wycombe and Kingsmead to make a single new depot and business support centre in Slough.
Sustainability was a key factor in its design with features such as LED lighting throughout and a highly efficient ammonia refrigeration plant. Although our Slough site is almost three times the size of High Wycombe and Kingsmead depots combined, we have achieved a 2% reduction in energy use compared to the previous sites. This is a saving of over 15 tonnes of CO2.
Energy Working Group
Our Energy Working Group has been working hard over the past year to develop our energy strategy.
Having carried out a survey and consulted with our trusted advisors, we have identified 15 improvement opportunities and prioritised them in terms of scalability, carbon reduction, return on investment and business continuity, and created an energy strategy. The strategy will be approved by our Leadership Team and implemented during 2017/18.
We are members of the Courtauld 2025 Water Working Group and share its collective aim to improve water use efficiency. In order to do this we have a water reduction target in place so that we can monitor use and deliver year on year reductions.
LED replacement programme
Our facilities team has been replacing LED light fixtures and fittings that were installed five years ago over 17 sites. We project that this will ensure a 4% reduction in electricity use and over 560 tonnes of CO2.
Wakefield solar roller shutter doors
Our Wakefield depot has two solar powered shutter doors. They each have their own PV (Photovoltaics) panels and batteries capable of storing and powering a loading bay up to 100 times without charge. Even with the PVs disconnected, based on the current usage and the battery storage capabilities, each bay could continue to operate for up to four days, reducing the amount of energy pulled from the grid. This should result in a saving of approximately six tonnes of CO2 saved per annum across both doors.
Energy efficiency improvements – lower cost, lower carbon
Our energy strategy is already starting to reduce our operating costs and our carbon emissions. The work that we have done with our cross-functional Energy Working Group at our Nottingham depot is a great example of this. We have implemented three key changes that have had a notable impact:
- A load shedding programme within the refrigeration plant that ensures the cycle occurs at the best time without affecting product temperature
- Changing the battery charging time for the mechanical handling equipment – fork lift trucks and manual equipment
- Changing the operating temperatures of the refrigeration plant
Together, these measures mean that the depot saves on electricity consumption, runs more efficiently and with lower carbon emissions. Our aim is to roll out these operating principles across our estate to save electricity and get further reductions in our carbon footprint.
