Savanna burning: Outline of the CFI methodology

The approved and Kyoto compliant savanna burning methodology is based on more than 10 years of research into fuel loads and burning efficiencies at different times of the year.

The methodology aims to reduce emissions from bushfire by reducing the area burnt each year and minimising late dry season fires, which on average emit 52% more emissions compared to early dry season burns.

This aim is achieved by the planned deployment of early dry season burns in combination with natural or constructed barriers to stop the spread (extent) of fire” (i.e. by establishing strategic firebreaks).

Reducing fire by introducing cattle to an area is not eligible under this methodology. Cattle may be present on the project area but should not be introduced or stocking rates increased.

This methodology only applies to areas that receive on average more than 1000mm of rainfall annually. Work is currently progressing on a second methodology for the 600-1000mm zone.

This methodology only applies to eucalypt open forest / woodland, or sandstone woodland / heath. The methodology does not apply to wetlands, grasslands or eucalypt communities with exotic grass understorey (e.g. gamba grass). However, additional vegetation types may be added in the future.

The methodology requires the development of vegetation and fire maps (1:100 000 scale) for the project area and is likely to require professional assistance.

The methodology only applies to emissions of nitrous oxide and methane. Carbon dioxide emissions are not recorded because they are likely to be re-absorbed by the landscape in the next growing season. Fuels expended during fire management must be included when calculating net annual abatement. Reporting and auditing is required.

Annual abatement is calculated by subtracting the annual emissions from a baseline level. The baseline is calculated from the ten years prior to commencement of the project to represent emissions from unmanaged fire. This baseline period can be back-dated up to six years if strategic fire management has already commenced. You will not be penalised (e.g. credits taken from you) if your annual emissions happen to exceed you baseline.

Project viability may depend on baseline level of emissions and the ability to reduce the baseline with strategic early dry season burns. The cost of management, maps and calculating emissions (or engaging third parties) may affect viability. Costs could be reduced if properties amalgamate into a single project. Please email if you are interested in being involved in a feasibility study.
