Current research programme
The NZAGRC-PGgRc methane research programme builds on the NZAGRC's 2010-2013 methane science objectives and the PGgRc's methane work programme from 2007-2013.
The NZAGRC-PGgRc methane research programme pools New Zealand's resources to identify the most effective and practical solutions for reducing methane in New Zealand's agricultural industry.
Our research programme aim is to deliver efficient, cost effective, highly productive, on-farm solutions to ensure New Zealand agriculture is economically and environmentally sustainable through the reduction of agricultural greenhouse gas emissions.
The 'Mitigating Methane Emissions' research programme has four main aims for delivery in the next one to three years:
- Develop low methane-emitting breed selection tools
- Develop low GHG forage farm systems
- Develop a methane reduction vaccine solution
- Discover and test ruminal methane inhibitors that maintain productivity levels
There is also a feasibility study being undertaken to understand the potential to capture and convert methane in soil and a validation trial of a rapid, low cost system for measuring methane.

Dr Peter Janssen is the Principal Investigator of the PGgRc-NZAGRC methane mitigation programme at AgResearch, and co-ordinates and contributes to the different work streams developing technologies to reduce ruminant methane emissions. He has...
More farmers are aware of the impact of livestock on global warming, says an agricultural greenhouse research expert. New Zealand Agricultural Greenhouse Gas Research Centre director Dr Harry Clark said farmer awareness of their...
Wednesday, 19 October 2016 The Parliamentary Commissioner for the Environment’s report into greenhouse gas emissions from agriculture highlights the need for a suite of mitigation solutions rather than a single silver bullet....
Global solutions to reduce methane emissions from ruminant animals are feasible, because the microbes causing the emissions are similar around the world
The New Zealand-led “Global Rumen Census” project analysed the microbes responsible for ethane emissions from a wide range of ruminant animals around the world. The project found imilar bacteria and methanogens dominate in nearly all...
Dr Suzanne Rowe, co-leader of the NZAGRC-PGgRc programme to breed low methane ruminants, has always been passionate about farming. Originally from Devon, in the UK, she grew up in the city and left home at 16 to work on a horse breeding...
Rick provided the conference delegates with an overview of the New Zealand investment landscape for reducing agricultural greenhouse gases. He highlighted that New Zealand is putting in a great deal of effort into reducing agricultural greenhouse...
Peter gave an interesting overview of how ruminants produce methane and the strategies that are being investigated for reducing, or even eliminating, this methane. Feeds which lead to reduced methane production have been studied and the...
John provided further detail about the low methane emitting sheep breeding programme. There is excellent rationale for this strategy given that for most farmed species (plants and animals) genetics contributes around 50% of the farm system...
Tim presented an international perspective on the methane research being conducted globally. There is research being conducted to investigate both: (i) technologies to reduce emissions and ii) ways to increase efficiency across the...
Animal variation project provides wealth of... (0.66MB)
News release from DOE JGI, 17 June 2014 excerpt "...not all ruminants are equal when it comes to greenhouse gas emissions. It turns out that the amount of methane produced varies substantially across individual animals of the...

Methane rumen (0.23MB)
What's really in a rumen? It's probably something that most people haven't given much thought to. However, in the search for methods and technologies to mitigate methane produced from ruminant animals, this is a key question. The...
Could forage rape, a brassica crop, hold the key to understanding what and how to feed animals to reduce their greenhouse gas emissions? A wide search has been carried out to date for animal feeds that reduce GHGs. For a long...
Much effort and intellectual grunt is going into solving the livestock methane emissions problem. Peter Burke reports on this science challenge facing New Zealand. A TINY micro-organism one thousandth of a millimetre long is proving a huge...
