On August 13, 2025, the Australian Competition and Consumer Commission (ACCC) granted authorisation AA1000696 to the Victorian Water Industry Association along with 15 participating Victorian water corporations. This authorisation allows them to collectively acquire and generate Australian Carbon Credit Units (ACCUs) to help meet their greenhouse gas emission reduction obligations.

The ACCC's decision is valid until July 1, 2035, providing a long-term framework for these corporations to work together in addressing environmental challenges. The commission believes that this collective approach will lead to significant public benefits, including efficiency gains and reduced transaction costs.

In its assessment, the ACCC concluded that the anticipated public benefits from this collaboration would outweigh any potential public detriment, thereby justifying the authorisation. Further details regarding the application and the ACCC's decision can be found on the ACCC's public register.
