Greenhouse Accounting Framework (GAF)

Farm Table says:

The Greenhouse Accounting Framework provides free, industry-specific Microsoft Excel calculators for measuring on-farm greenhouse gas emissions across Australian agriculture.

Framework Overview and Coverage

GAF Tools offer modular, enterprise-specific spreadsheets covering major sectors:

  • D-GAF (Dairy): Enteric methane, manure N2O, feed production emissions
  • SB-GAF (Sheep & Beef): Livestock methane, pasture N, soil carbon change
  • G-GAF (Grains/Cropping): Fertiliser N2O, fuel, stubble decomposition
  • H-GAF (Horticulture): Irrigation energy, synthetic N, plastic films
  • Additional calculators: Cotton, poultry, rice, feedlot modules

Key features:

  • Aligned with Environmental Markets Platform (EAP) v1.1.0 for certified carbon projects
  • Predicts emission hotspots (e.g., N2O from over-application, CH4 from poor effluent)
  • Soil carbon add-on: Simple model for SOC change from management practices
  • Decision support: Scenario testing for mitigation options (inhibitors, covers)

The Greenhouse Accounting Framework Tools represent a gold standard in accessible, scientifically-robust emissions accounting for Australian agriculture. By delivering enterprise-specific Excel calculators aligned with national inventory standards, GAF bridges the gap between complex science and farm-level decision-making.
