We are obligated to report GHG emissions and energy consumption in accordance with the Companies (Directors’ Report) and Limited Liability Partnerships (Energy and Carbon Report) Regulations 2018. To calculate our emissions, our methodology follows GHG Protocol Corporate Accounting Standard, using an operational control approach.
For both energy and emissions data, we have included all subsidiaries within the Group measure, and have included all UK-based subsidiary operations within our consolidated UK measure.

Energy efficiency measures

We continue to invest heavily in energy efficiency across all our operations. Key initiatives include:
- LED lighting upgrades across the entire Group estate.
- Installation of aerofoil technology across all our UK stores, saving 15% energy use in fridge operation.
- Invested in high efficiency ventilation fans.
- Trialled Lightfoot® telematics which improves driver efficiency. Initial findings indicate 7% improvement in miles per gallon fuel consumption.
- Continue to optimise distribution and home delivery operations to reduce road miles and secure efficiencies.
