Energy and emissions

As one of Australia’s largest companies, we understand our responsibility to minimise our environmental footprint, as well as to mitigate the environmental and social impacts of climate change.

Coles Group has made the following commitments:

  • To deliver net-zero greenhouse gas emissions by 20501;
  • For the entire Coles Group to be powered by 100% renewable electricity by the end of June 2025, building on the progress already made towards this target through renewable power purchase agreements, onsite solar and agreements with renewable electricity generators; and
  • To reduce combined Scope 1 and 2 greenhouse gas emissions by more than 75% by the end of FY30 (from a FY20 baseline).
  • NEW in FY23: A supplier engagement target, committing that 75% of our suppliers, by spend, covering purchased goods and services, and upstream transportation and distribution will have science-based targets by FY27.

Note 1: At this point in time, Coles’ commitment refers only to Coles’ Scope 1 and Scope 2 emissions.

Reducing our own greenhouse emissions is a key part of our climate change response. We will continue to invest in initiatives across renewable electricity, energy efficiency and alternative refrigerants.

We will continue building the resilience of our businesses, and supporting the community, against climate impacts. Whether it's getting stock through floods or working with emergency services and food rescue organisations to support communities devastated by bushfire. 

Renewable electricity

In March 2021, Coles Group committed to being powered by 100% renewable electricity by the end of June 2025.

Coles was the first major Australian retailer to commit to buying renewable electricity through a power purchase agreement in 2019.

We have made significant progress this year towards our 100% renewable electricity target through onsite solar and large scale generation certificate (LGC) arrangements which match our consumption. 

Coles has now committed to purchasing 100% of the renewable electricity required to meet its June 2025 target, once the agreements commence. 

We're also installing solar power at many of our supermarkets. This helps reduce the stores’ environmental footprint and keep energy costs down. Installing solar power is part of Coles’ commitment to increase the amount of electricity we source from renewables.

Environmental stores

We're reducing the environmental footprint of our stores by cutting back on energy used in refrigeration. We've installed night blinds on open refrigeration cases and have LED lighting in all supermarkets.

Where practicable, we are introducing other technologies to improve the energy efficiency of refrigeration systems:

  • Coles’ refrigeration management program includes increasing the use of natural refrigerant gases, which have close to no global warming potential (GWP) compared to older synthetic refrigerant gases. 
  • We are continuing with our refrigeration pipe replacement program and increasing investment in leak-detection technology, further reducing gas loss. 
  • Doors on refrigeration units across most categories to help reduce energy consumption.
  • Commencement of a gas submetering program aimed at improving our visibility of gas usage and energy efficiency.
