“Know your numbers, and have a plan.”
By the end of 2022, all of our farms need to know their greenhouse gas numbers. Knowing your numbers is the first step towards managing and knowing how to reduce, your nitrous oxide and methane emissions, and maintaining and increasing your on-farm sequestration.
Two sources of information from He Waka Eke Noa: The Primary Sector Climate Action Partnership can help industry bodies and farmers understand their agricultural greenhouse gas emissions, mitigation, and sequestration options.
This is a guide for farmers and growers to help measure, manage and reduce greenhouse gas emissions and identify sequestration opportunities.
AgFirst assessed publicly available tools to ensure that they used methodologies and definitions that are appropriate for He Waka Eke Noa. More tools will be assessed over the next three months, including Beef + Lamb New Zealand’s GHG calculator, and tools from Toitū, Foundation for Arable Research (FAR), and New Zealand Pork.
Assessed so far are HortNZ, MfE, Alltech, E2M, Fonterra/AIM, Farmax and Overseer.
Every farm in New Zealand needs to know its numbers by the end of 2022. Around 11,000 farmers already have a GHG number for their farm.
It’s good to get a handle on your GHG numbers now, so you can start thinking about how to manage and potentially reduce them.
The more farmers and growers can show we know our numbers and have a plan, the better for our reputation with customers, the community and the Government. The He Waka Eke Noa partnership is working towards the primary sector having a greenhouse gas management system that works for us, so it’s important to meet our milestones.
Some tools also let you estimate sequestration on your farms, and it’s good to start getting an understanding of that too.
Not all farms have the same opportunity to reduce emissions, and some are already highly efficient, but the choices each farmer makes will have a collective impact on Aotearoa’s agricultural greenhouse gas emissions.
The Partnership is still working to develop the farm-level emissions pricing system for 2025. The definition of a farm and tools approved for use in the ultimate pricing system may be different to those that are available now to help farmers understand your emissions numbers.
