Fonterra has introduced on-farm greenhouse gas emissions profiles which it says will help its farmers better understand where their on-farm emissions are coming from and how they can reduce them.
After undertaking a pilot involving about 100 farms, the dairy co-operative is now making the individually tailored reports available to the approximately 9500 farms which supply it milk.
Fonterra director for on-farm excellence Charlotte Rutherford said using data provided by its farmers, it could estimate the amount of biological methane and nitrous oxide emissions occurring on each farm and the amount of emissions per kilogram of milk solids.
She said it also showed farmers the source of the emissions.
