About the GHG Emissions Calculator

This tool estimates total greenhouse gas (GHG) emissions from agricultural operations based on livestock numbers, fertilizer use, energy consumption, and land practices. It calculates your farm's carbon footprint in CO2 equivalents (CO2e) and suggests reduction strategies aligned with climate-smart agriculture.

Formulas Used

1. Source Emissions:
Emissions = Quantity × Emission Factor

2. Total Emissions:
Sum of emissions from all categories

3. CO2 Equivalent:
Expressed in tonnes per year across all gases (CH4, N2O, etc.)

4. Category Contribution:
% = (Category Emissions ÷ Total Emissions) × 100

5. Reduction Potential:
Potential = Source Emissions × Reduction Rate (%)

Example Calculation
  • 20 dairy cows × 3.1 = 62 t CO2e
  • 5 tonnes nitrogen fertilizer × 3.8 = 19 t CO2e
  • 2,000 liters diesel × 2.7 = 5.4 t CO2e
  • 1 ha rice = 4.6 t CO2e

Total = 91 t CO2e/year

Real-World Applications
  • Track your carbon footprint for sustainable certification
  • Evaluate emission hotspots in your operation
  • Plan mitigation actions like renewable energy or better feed
  • Use results to qualify for carbon credits or ESG reports
How to Use This Calculator
Step-by-Step Guide
  1. Enter livestock numbers (heads or 100 heads)
  2. Input annual fertilizer use in tonnes
  3. Add your energy use: fuel, electricity, gas
  4. Specify land use areas like rice or deforestation
  5. Click Calculate Emissions
  6. Review charts, reduction tips, and download reports
Tips for Accuracy
  • Use real fuel bills or logbook data for energy inputs
  • Record manure and fertilizer weights from farm logs
  • Use updated emission factors for region-specific accuracy
Pro Tip: Run this tool quarterly to track seasonal emissions and progress toward net-zero goals.
Frequently Asked Questions (GHG)

CO2 equivalent is a standard unit to express all greenhouse gases (methane, nitrous oxide, etc.) as an amount of carbon dioxide based on global warming potential.

Yes, it gives an initial baseline estimate. You’ll still need third-party verification for carbon credit programs.

Livestock emissions come from digestion and manure, while land-use emissions are from practices like rice paddies, tillage, or deforestation.

Switch to precision inputs, renewable energy, reduce tillage, and manage manure more efficiently. See the suggestions in your result panel!
