Agricultural greenhouse gases & the New Zealand deer industry

Quick facts

  • Forty-nine percent of New Zealand's greenhouse gas emissions come from agriculture.
  • At the same time, more than 38% of New Zealand's merchandisable exports come from agriculture. 
  • Total New Zealand deer numbers (at 30 June 2015) exceed 907,000
  • Venison exports total 14,869 tonnes (at September 2015)

What's changed in the beef & sheep sectors since 1990 in on farm practices?

  • Increased carcass weight
  • Shorter time to slaughter


What's the impact of these on farm changes on productivity?

  • Increased finished weight of animal 
  • Increased meat yield per hectare (kg meat/ha) 

What's the effect of these changes on emissions intensity? 

Emissions intensity of the New Zealand deer sector is lower and a great proportion of feed goes to production rather than maintenance.

What else is being done to lower emissions on farm?

The NZAGRC is working in partnership with the PGgRc to explore options to mitigate GHGs on New Zealand farms.  An overview publication is available for download

How can I estimate my on farm GHG emissions?

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.
