In 2025, CBA consumed a total of 31.85 million Gigajoules of energy across its operations. Of this total, 84.81% was sourced from renewable energy, either derived from natural resources like biofuels, biomass, or biogas, or generated using renewable technologies such as solar or wind power. The remaining 15.19% was classified as non-renewable energy, coming from fossil-based fuels such as coal, natural gas, or crude oil, or from non-renewable generation technologies like nuclear power.a
In 2025, CBA consumed a total of 31.85 million Gigajoules of energy, of which 84.81% was derived from renewable sources, including biofuels, biomass, biogas, solar, and wind power.a
This high level of renewable energy use suggests that CBA has taken strong steps toward decarbonizing its energy supply and reducing its dependence on fossil fuels.
Since 2022, CBA's total energy consumption remained relatively stable, but fell by 5.34% in 2025, possibly indicating early signs of energy efficiency improvements.a
Over the same period, the share of renewable energy in CBA's consumption increased by 3.96%, including a 2.59% increase in 2025, showing consistent progress in clean energy adoption.a
Overall, CBA’s energy trends reveal a complex picture, with variations in total consumption and renewable sourcing. A closer examination of operational drivers and sourcing strategies is needed to fully assess the company’s environmental impact.
