Transcript of "On-farm greenhouse gas audit - Mark McKew"

  1. 1. On-FarmGreenhouse Gas Audit Mark McKew
  2. 2. Outline• Farming operation• How the project came about• Why I wanted to get involved• Results• What have a learnt from this process• Future?
  3. 3. Coralynn• 654 ha• Sheep (2,700) and Beef (77) Production• 24ha crop, 10ha revegetation• Mt Cole Creek, Western Victoria
  4. 4. How the project came about• Project Platypus (Local Landcare Network) sought funds from the Federal Govt to Audit 15 farms.• The project was managed by the Landcare Network who engaged Environmental Accounting Services to design and undertake audits.• Project Platypus staff were involved by working with landholders to collect information.• It was decided to use the previous financial year as a basis for calculating emissions
  5. 5. Why I wanted to get involved• Concerns about Global Warming, requires a Global solution• Want to play my part in the solution (everyone needs to get involved)• No idea about what my farming enterprise emissions were• My goal is to become carbon neutral
  6. 6. Accounting Boundary Emissions/Uptake Carbon Dioxide Nitrous Methane Oxide Farm Emission/Uptake Sources Physical Inputs Physical Outputs Enteric Fermentation Fuel and Energy Use Fuel Emissions from Fertiliser Use Wool Emissions from Animal Waste Grain Fertiliser Emissions from crop Liveweight Stock Numbers residues Total Farm Area Area Cropped Emissions to Air Area of Improved Pasture Physical Inputs Physical Outputs (Not Counted• Increase/decrease in soil carbon was not considered as part of this audit

  9. 9. Learnings• Carbon accounting for my enterprise was not complicated• Assumed beef were higher emitters of methane than sheep, but on a DSE basis they are only marginally higher • Crops as opposed to livestock produces a lot less greenhouse gases • Need to undertake a substantial amount of revegetation to become carbon neutral (or through soil carbon increases)
  10. 10. Future direction• Reduced cattle numbers• Increase in revegetation• Commenced testing soil carbon at a number of sites over the farm• Learn more about how to reduce emissions from livestock through genetics and feeding• We need to undertake a substantial amount of research and development in this area
