Collaboration of the Year

Waitrose, as part of the John Lewis Partnership, has set stringent energy and carbon targets for its business.

The partnership is working to reduce absolute operational CO2e emissions by 15 per cent by 2020/21 against the 2010/11 baseline.

The partnership has elected to work to a responsible development framework, which stipulates that all works must be carried out in a sustainable and responsible manner.

Energy and carbon emission reductions are being targeted across the partnerships operations and it was clear that energy consumption within branches was a major contributor, one that warranted a specific focus while delivering within the responsible development framework criteria.

Waitrose Engineering realised this required a cross-discipline approach and engaged with the parties listed above with a clear brief: to engage with all interested stakeholders to ascertain the parameters within which the stores needed to operate.

As well as the energy used by commercial refrigeration systems, annual refrigerant gas loss was identified as a significant factor in emissions that needed to be tackled.
