In New Zealand, In New Zealand, farmers can get a farm-level estimate of their greenhouse gas emissions (methane and nitrous oxide, and in some cases also energy use) using commercially available calculators, such as OVERSEER.

These calculators tend to rely on the use of default emissions from specified activities and only take into account a limited number of the factors that influence greenhouse gas emissions in practice. They are, however, useful for assessing how emissions change over time in response to management decisions such as fertiliser use and changes in animal numbers.
