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

OPINION: Farmers advocate takes wrong message from climate reports - Andy Reisinger

As a climate scientist, I strongly rebut Tuesday's opinion piece by Robin Grieve who claimed he was relating facts from the Motu Research report, Cows, Sheep and Science: A Scientific Perspective on Biological Emissions from Agriculture, that I co-authored, and a report from the Parliamentary Commissioner for the Environment, both of which came out last year.
