We're committed to helping customers reduce their home energy bills and their environmental footprint

  • As the largest retail bank in the country, we have a responsibility to meet the current needs of our customers and the community, while operating sustainably for future generations. According to the Australia Institute, 70% of Australians are concerned about climate change and its impacts, including the potential to exacerbate existing cost-of-living pressures.

    As a signatory to the Net-Zero Banking Alliance (NZBA), we acknowledge the role we have in supporting our 11 million retail customers to understand their environmental footprint, reduce their emissions and encourage sustainable practices.
