Assessment Parameters

This calculator is a simplified approximation of the greenhouse gas emissions from a farm.

For a more accurate estimate, programs such as Overseer should be used - as these take into account a far larger number of variables including soil, climate and animal performance.

This calculator is based on the averages and emission factors used in the New Zealand Greenhouse Gas Inventory (2016).
