Quantify on-farm greenhouse gas emissions
and soil carbon sequestration

Demonstrate good practice

Farmers manage for cost, productivity and soil health. The Cool Farm Tool can show how these management decisions sequester carbon or reduce greenhouse gas emissions – an issue customers care about.

Quick and easy

It takes just 10-15 minutes to get a rough estimate, and the calculations are based on information you will have on hand or easily accessible.

Stimulates thinking

The Cool Farm Tool isn’t just a calculator. It stimulates thinking about management, by showing hotspots and helping to develop action plans.

Results tailored to your field

Reducing tillage and adding cover crops can reduce and offset problem emissions while building soil health. But each farm and field responds differently. The Cool Farm Tool allows farmers to find out how their fields respond to the management options of interest.

Encourage good agriculture practice

With an interactive interface designed to be simple to use, but scientifically robust in the complex arena of carbon accounting, the Cool Farm Tool encourages, motivates and rewards good agricultural practice.

Tested and Adopted

The Cool Farm Tool has been tested and adopted by a range of multinational companies who are working with their suppliers to measure, manage, and reduce greenhouse gas emissions in the effort to mitigate global climate change.

Crop Data Requirements

  • Harvested yield and marketable yield product weights
  • Growing area
  • Fertiliser applications: type and rate
  • Number of pesticide applications
  • Energy use (kWh and fuel use)
  • Optionally: transport: mode, weight of product and distance

Livestock Data Requirements

  • Herd or flock size
  • Feed
  • Manure management
  • Energy use (kWh and fuel use)
  • Transport of feed and other inputs

Enter data and then modify entries to see how much of a difference available changes will make on your farm. Download the complete data requirements for crops here.

The CFT greenhouse gas emissions calculator is based on empirical research from a broad range of published data sets and IPCC methods. Unlike many other agricultural greenhouse gas calculators, the CFT includes calculations of soil carbon sequestration, which is a key feature of agriculture that has both mitigation and adaptation benefits. The tool calculates emissions estimates from:

• N2O emissions based on an empirical model built from an analysis of over 800 global datasets. These datasets refine IPCC Tier 1 estimates of N2O emission by factoring in the guiding drivers of N2O emissions such as rate of N applied, soil texture, soil carbon, moisture and soil pH,
• Soil carbon sequestration based the results of published studies built from over 100 global datasets
• Embedded fertilizer production emissions based on the most up to date, peer reviewed industry data.
• Fuel and electricity use utilizing standard conversion factors, taking into account the energy mix of each country and territory.
