Approved Reef Credit Methodologies
There are currently two approved methods to undertake Reef Credit Projects that provide verifiable Pollutant reductions. Projects operating under the Reef Credit Scheme must use an approved Reef Credit Methodology to quantify Pollutant reductions. Methodologies may be developed for any practice change or ecosystem repair activities that are able to reduce or remove Pollutants entering the Great Barrier Reef.
The Method for Accounting Reduction in Nutrient Run-off through Managed Fertiliser Application Version 1.1 quantifies the reduction in Dissolved Inorganic Nitrogen (DIN) lost from agricultural land through improved soil and nutrient management practices within the catchments of the Great Barrier Reef World Heritage Area.
The scope of this methodology includes reducing DIN loss through more efficient soil and nutrient management practices from agricultural enterprises including (but not limited to) sugarcane, bananas, grains and fodder. The methodology allows for a range of practice changes that lead to a reduction in DIN loss across the project area.
The methodology was developed by GreenCollar Group Limited.
The Method for Accounting for Reduction in Sediment Run-off through Gully Rehabilitation Version 1.4 describes the approach to achieve and quantify reductions in Fine Sediment (FS) from rural landscapes through gully rehabilitation, within the catchments of the Great Barrier Reef World Heritage Area.
The scope of this methodology includes the design and implementation of landscape rehabilitation measures to reduce the amount of sediment loss from gully erosion. Gully rehabilitation interventions may include:
1) Engineered rock-chute head control structures;
2) Engineered grade control structures;
3) Gully reshaping and capping with rock or mulch, or both;
4) Gully catchment drainage diversion structures (contour-banks and flow-spreaders);
5) Soil amelioration (i.e. with gypsum and other non-toxic chemical stabilisers);
6) Revegetation of treated gullies and gully catchments;
7) Grazing management in treated gullies and gully catchments;
8) Other interventions undertaken to rehabilitate gullies which are fully described by the proponent in the Gully Rehabilitation and Management Plan.
The methodology was developed by GreenCollar Group Limited.

Methodology development
Methodologies may be developed for any practice change or ecosystem repair activities that are able to reduce or remove Pollutants entering the Great Barrier Reef. Reef Credit Methodologies must comply with the Reef Credit Standard requirements for methodology development and approval.
