Why do farmers need greenhouse gas (GHG) accounts?
Dive into Topic 3 of DAFF’s Carbon Farming Outreach Program training to learn how a greenhouse gas (GHG) account quantifies and records your GHG emissions and carbon storage. This topic will help explain GHG accounting and the reasons for doing it, which include being able to quantify productivity improvements and other co-benefits of carbon farming.
Why is this important? Well, as this training program highlights: “If selling produce internationally, farmers may need GHG accounts to demonstrate their emissions management credentials.” As we get closer to 2030 and 2050, when Paris Agreement reporting milestones kick in, major international companies who buy produce from Australia will increasingly want to know about all of their suppliers’ emissions. So now is the time to start getting to grips with the data they’ll want, and to begin keeping those records.
For a starting point, let’s have a look at understanding emissions:
And how are you supposed to measure these emissions? Well, you don’t – it’s more a case of calculating them. There’s been a lot of research, trial and error and testing to build simple and reliable calculation tools that you can use, with a range of different calculators available depending on what you grow and why you want to record your emissions. If you have stats to hand such as your property size, land use, location, livestock numbers, power and chemical inputs, etc, then you’re most of the way there.
Did You Know?
A recent study on greenhouse gas emissions in grain farming systems has confirmed that fertiliser is by far the biggest contributor. Graphs from three DPIRD Western Australian Farming Systems projects sites at Northampton, Merredin and Lake Grace tell a compelling story.
