The Science and R&D to help livestock producers to get to CN30

  • Carbon neutrality can be reached either through emissions avoidance (e.g. reduction of enteric methane), emissions offsets (i.e. carbon sequestration), or both. For a given area, carbon offsets can be higher than both emissions avoided and the total emissions from the farm.
  • As an industry, a combination of emissions avoidance and emissions offsets technologies, skills and practices will be needed. In some areas, carbon sequestration will have greater potential, in other areas emissions avoidance (e.g. animal supplements) will be more effective: a number of approaches will be needed if the entire Australian red meat sector is to reach carbon neutrality.
  • While our past work has shown that income from direct carbon credits is often small, greater returns can be derived from co-benefits to livestock production, including that provided by shade and shelter belts.
  • There has been less work on economic, environmental and social implications of GHG emissions mitigation technologies, particularly as part of a whole system. By way of example, interventions that improve livestock growth rates only have mitigation benefit if whole farm stocking rates are not subsequently increased, e.g. if animals removed from a farm are not replaced by others.
