Current actions
The greenhouse gas actions listed on this page have been verified by science and are available to farmers now.
These actions have been comprehensively researched under New Zealand conditions and there's scientifically robust data available that demonstrates they can reduce on-farm greenhouse gas emissions. They're also captured in New Zealand's greenhouse gas inventory - the national system used for reporting emissions and mitigations.
Many farmers are already implementing these actions. They won't necessarily work in all farm systems, and the emissions reductions achieved will vary from farm to farm. However, even though they may only lead to small reductions, they add up. They can also make a difference for other farm objectives, e.g. freshwater.
-
Stocking rate and performance
Small changes to stocking rates, feed use and animal performance can improve efficiency while maintaining productivity. On some farms, fine-tuning the farm system can reduce greenhouse gas emissions by up to 10%.
-
Nitrogen fertiliser
For some farms, reducing nitrogen use or applying it more strategically can lower nitrous oxide emissions and reduce costs without significantly affecting production. The right approach will depend on your soils, climate and farm system.
-
Low-emission feeds
Research is showing that feed choices may help reduce emissions while still supporting good production and animal performance. What works will depend on your farm system, feed availability and economics.
-
Trees and vegetation
There are many benefits from planting trees or restoring woody vegetation on a farm, including to help combat climate change by removing carbon dioxide. However, it's a complex topic.
-
Efficiency improvements
Efficient farm systems often produce fewer emissions per unit of product. There is no one-size-fits-all approach, but improving resource use can support productivity and long-term resilience.
-
Land use change
Changes in the way land is used can help to reduce greenhouse gas emissions.
