About the Supply Fund

The Supply Fund buys credits based on demand from development and infrastructure projects. Credits are then sold to public or private sector proponents who need credits to offset the biodiversity impacts of their projects, or other buyers who may seek credits for philanthropic or strategic purposes.

The Supply Fund is operated by the Department of Climate Change, Energy, the Environment and Water with the aim of making credits easier to sell and buy, improving the functioning of the biodiversity market. The department will apply fair, transparent and ethical processes and decision-making when buying and selling credits through the Supply Fund.

Biodiversity credits are generated through biodiversity stewardship agreements. The sale of credits provides funding for landholders to improve the management of pests, weeds and fire and restore habitat. 

Operating Protocol

The Operating Protocol document sets out how the Supply Fund operates. It covers governance, ways to identify demand and supply, methods for buying and selling credits, and monitoring and reporting.
