Welcome to the FarmGAS greenhouse gas (GHG) emissions calculator. FarmGAS can be used to estimate your farm’s annual GHG emissions, both at the individual enterprise activity level and for the farm as a whole, and to examine the financial impacts that different greenhouse mitigation options may have on farm business profitability.

By creating a log-in, you can estimate the financial and greenhouse implications of changing enterprise mix or production options within your farm business by creating ‘scenarios’ online. The calculator is free to use, and you can access your information at any time.

Australian farm businesses will not be included as participants in the Australian Government’s Carbon Pollution Reduction Scheme until 2015 at the earliest. Therefore farmers will not be liable for farm emissions until at least that time. The FarmGAS Calculator provides an estimation of farm greenhouse emissions but is not associated with the CPRS. FarmGAS is simply a decision support tool, which can be used for scenario mapping.

The calculator applies the same methodology used by the Department of Climate Change in the estimation of Australia’s National Greenhouse Gas Accounts (NGA). Although major livestock and cropping enterprises are provided, FarmGAS does not currently include calculators for dairying, cotton or rice production.

The FarmGAS calculator project has been managed by the Australian Farm Institute, using funding provided under the National Heritage Trust, administered by the Department of Agriculture, Fisheries and Forestry through the National Agriculture and Climate Change Action Plan: Implementation Program. Further information about climate change and the NGA methodologies for the estimation of GHG emissions and sinks can be accessed from the Department of Climate Change website at http://www.climatechange.gov.au/index.html

The FarmGAS Calculator does not include a Dairy enterprise. The Dairy Greenhouse gas Abatement Strategies Calculator (DGAS) is available here
