Horticulture (no stock)

 

This Farm Carbon Calculator will estimate the amount of greenhouse gasses produced by farming activities (in units of C02eq) using Life Cycle Assessment.

Fill in the hectare value and select the type of farm, then fill in the other tabs as appropriate.
The Results tab will show a summary and pie chart of your farm C02eq emissions.


See the Information Sheet (PDF) for more details on the type of data and calculations used.
View the Disclaimer for limitations.

Enter the average number of head of each type of stock on the farm last year


Stock Type   Number

Animal/Field Emissions

(Fill in the values below only if you use the OVERSEER program)


Type
kg CO2eq/ha
Methane
Nitrous Oxide



The IPCC methodology and NZ GHG Inventory (July 2007) default values have been used (with some modifications to dairy) to calculate stock and field greenhouse gas emissions. Please note these are NZ averages and use broad stock classes. The most accurate stock emissions will be determined using OVERSEER, and these can be included above.
