Using energy efficiently and reducing greenhouse emissions

Coles recognises that investing in energy efficiency initiatives helps to minimise its environmental impact while also reducing costs. Most of the energy used in supermarkets is for refrigeration, lighting, cooling and heating.

In FY18, Coles invested $25.4 million in energy efficiency projects.

This included replacing lights with LED, installing solar photovoltaic systems and improving refrigeration and air-conditioning systems.

Coles began its LED replacement program in 2012 and plans to complete it in FY19, when every light in every supermarket will be LED.

In FY18, the business installed solar panels on 20 supermarkets taking the total number of supermarkets with solar to 26. This investment will continue with plans in development for further installations on existing supermarkets and solar now on the design blueprint for new stores.

Coles increased its number of supermarkets by eight and liquor and convenience stores by 25 over the reporting period. While the total floor area increased by 1.6  per cent, Coles electricity consumption decreased by one per cent compared with the previous year.

Greenhouse gas emissions

While growing its store network, Coles’ carbon emissions have continued to decline over the past ten years due to energy-efficiency initiatives and a focus on reducing emissions from refrigerant gases.

To reduce refrigerant gases, Coles is continuing a refrigeration pipe replacement program, transitioning to lower global warming potential (GWP) refrigerants, piloting zero GWP refrigeration plants and investing in leak-detection technology and a leak-detection team.

Since 2009, Coles reduced its greenhouse emissions by more than 30 per cent, meeting its 2020 target for emissions reduction four years early in 2016. In FY18, greenhouse gas emissions decreased by 2.5% compared with the previous year.
