The Australian Carbon Industry Code of Conduct (Code) is undergoing its second Independent Review to reflect legislative and policy changes as well as addressing evolving industry concerns.

The Australian Carbon Industry Code of Conduct (Code) was introduced on 1 July 2018 by the Carbon Market Institute (CMI). The Code is one of the world’s earliest voluntary, national codes for the carbon industry. It is designed to promote and support market integrity, consumer protection and accountability for industry practitioners and service providers across Australia.

The Independent Review will be led by Vicki Mullen, a Senior Consultant with Finity’s Climate and Sustainability Practice, who will enable stakeholders to have input into the ongoing maturity, development, and integrity of Australia’s carbon industry, as well as provide recommendations on the Code’s future direction and scope.

Ms Mullen is a lawyer with 30 years of experience in public policy and regulatory affairs, including prior experience with industry and professional codes. Ms Mullen will be supported by leading climate actuary, Rade Musulin, and environmental scientist, Olivia Brodhurst.

The Independent Review will be conducted in accordance with the provided Terms of Reference, and is supported by the relevant governance provisions of the Code.

John Connor, CEO of the Carbon Market Institute, says: “The Code was recognised as an important contributor to integrity in the Australian Carbon Credit Unit framework by the Professor Chubb led ACCU Review but needs to continue to evolve and drive best practice beyond basic compliance with legislative responsibilities.”

“The Code plays an important role in protection of consumers, farmers, First Nations and financial institutions and is backed by a team that engages with Code signatories through annual report reviews and other educational activities. This Review is important to ensure the Code remains fit for purpose and consistent with current market developments and community expectations.”

Vicki Mullen, the Reviewer, says: “This Independent Review is commencing at a vital time for the carbon industry in Australia. Major policy developments, including the federal Government’s response to the Chubb Review recommendations and the Safeguard Mechanism reforms have placed a strong spotlight on the carbon industry and the ACCU Scheme.”

“We look forward to engaging with a wide range of market participants and stakeholders to gain feedback on how the Code may be further developed to support the evolution, growth and integrity of Australia’s carbon market.”

The Code currently has 38 signatories, one Industry Supporter (the Clean Energy Finance Corporation) and three Government Partners – being the NSW, Queensland, and Western Australian Governments.
