Get paid to improve your operations
with Reef Credits

Reef Credit projects enable farmers to invest capital in their business

Reef Credits is a voluntary environmental market scheme that financially rewards land managers within the Great Barrier Reef catchments for on-farm changes that measurably improve the quality of water flowing to the Reef.

Projects are carefully designed to achieve water quality outcomes without compromising agricultural productivity, and additional income stream generated through Reef Credits is yours to invest back into your operations.

Projects focus on improving nutrient efficiency and reducing the flow of Dissolved Inorganic Nitrogen into waterways through improved cropping practices or by establishing wetlands. Reef Credits also support gully restoration, generating Reef Credits by preventing the flow of fine sediment onto the Reef from agricultural land.

Each Reef Credit is a tradeable unit representing a 1kg of nutrient or 538kgs of sediment prevented from entering the Great Barrier Reef.

It’s good for the community, it’s good for your soil health, and also it’s good for the reef, so it’s a win for everyone. In my mind this is a farming system, moving forward, that is going to increase my productivity.

Who can undertake a project?

Anyone who is a landowner or land manager can undertake a Reef Credit project. Find out more about project development here. To find if your project or your property is eligible please contact GreenCollar.

Who administers the Reef Credits scheme?

The Reef Credits Scheme is administered by Eco-Markets Australia, an independent not-for-profit organisation.  This is similar to other successful voluntary environment markets  around the world and ensures the integrity of the market.

How much are Reef Credits worth?

The value of Reef Credits, like other environmental commodities such as carbon credits, depends on the supply and demand dynamics of the open market.

How are Reef Credit Methodologies written?

Reef Credit Methodologies can be written by anyone wishing to see particular types of projects developed.  Methods must comply with the requirements of the Reef Credit Scheme. The initial methods have been developed through collaboration between GreenCollar, NRM organisations, researchers, government and an expert advisory panel of scientific and other stakeholders.

Do the methods use modelling or water quality monitoring to quantify Reef Credits?

Some methods use modelling and others use water quality monitoring depending on the type of activity and availability of peer reviewed models.

Is Reef Credits a grant scheme?

No. Reef Credits are a market-based, non-government approach to improving water quality at the Great Barrier Reef. Credits are only generated when a specific, measured outcome is achieved. Income is derived from the sale of these credits to buyers and can be reinvested into farming operations.

Reef Credits – 3 different approaches to meet different needs

When Reef Credits launched in 2020, there was just one way farmers and other land managers could get involved – by improving fertiliser management to reduce the flow of dissolved inorganic nitrogen to the Great Barrier Reef.

Reef Credits or Grants – carefully considering the best options for you

Environmental markets are not dissimilar to farming or commodity markets. The difference being, instead of food or fibre production, environmental markets measure and place a value on and trade in cleaner air, water or improved habitat and biodiversity.

What are Reef Credits and how are they generated?

Being paid to implement best practice land management and deliver cleaner water to the Reef, without negatively impacting productivity may seem too good to be true. But according to GreenCollar Business Development Manager Bart Dryden, and the numerous farmers already running Reef Credit projects, it really is a win:win transaction that benefits both the farmer and the environment.
