Greenhouse Gases & Dairy Farms

Objective of the event

Provide dairy farmers and service providers with an introduction to the scientific issues and some policy implications regarding Greenhouse Gases and dairying.

Key Messages

The main greenhouse gases (GHGs)from dairy farms are CO2 – carbon dioxide; CH4 – methane; and N2O – nitrous oxide.

The largest sources of agricultural greenhouse gas emissions are Enteric Methane from ruminants, and Nitrous Oxide from soils.

The Dairy Greenhouse gas Abatement Strategies (DGAS) calculator is a greenhouse gas accounting tool available for dairy farmers.

Dairy farmers can reduce on-farm emissions by reducing unproductive cow numbers; extending lactation; adjusting feed quality, for example with dietary oils; and using nitrification inhibitors.

Reflections on the Event

This topic is somewhat challenging for farmers due to the political nature of the issue, but once you get beyond the politics farmers are keen to know more in order to better manage their farms. The workshop was very well received with most farmers rating the event as 8/10 or higher.
