Agriculture is second only to energy generation as a source of greenhouse gas emissions in Australia. Methane from cattle and sheep constitute 60% of these agricultural emissions. Their abatement is a win-win goal for the agricultural industry, reducing greenhouse emissions while increasing food efficiency. This project will develop a novel, cost- and-labour efficient method for on-farm measurements of the emissions of methane from free-grazing cattle and sheep in their undisturbed environment. The method will be used to assess the dependence of methane emissions on factors such as diet and the efficacy of proposed methods for abatement of methane emissions, as well as providing improved data to the National Greenhouse Gas Inventory.

农业是澳大利亚仅次于能源生产的第二大温室气体排放源。来自牛羊的甲烷占农业排放量的60%。减少温室气体排放对农业来说是一个双赢的目标，既减少了温室气体排放，又提高了粮食效率。该项目将开发一种新颖的、成本和劳动力效率高的方法，用于在农场测量自由放牧的牛羊在其未受干扰的环境中的甲烷排放量。 该方法将用于评估甲烷排放对饮食等因素的依赖性和拟议的减少甲烷排放方法的效力，并为国家温室气体清单提供改进的数据。
