Researchers have developed both the dairy and sheep Carbon Offset Scenario Tool (COST) to explore the influence of various abatement strategies on greenhouse gas emissions for Australian dairy, wool and prime lamb farms.

They cover abatement strategies related to diet manipulation, herd and breeding management, feedbase management and waste management, calculating the impact of each strategy on carbon dioxide, methane and nitrous oxide emissions, using both net emissions and emissions intensity, as well as on farm income.

Both the sheep COST and the dairy COST (now called 'DGAS') are available from the Greenhouse in Agriculture website.
