Scope 1, 2 and 3: what those numbers actually mean for your farm business

If you've been getting questions from your processor, bank or retailer about emissions data, chances are the words "Scope 1, 2 and 3" have come up. They sound technical, but the logic behind them is fairly straightforward, and understanding it goes a long way toward making sense of why you're being asked for this information at all.

Scope 1 covers emissions from sources your farm directly owns or controls. For most livestock producers, that's predominantly methane from enteric fermentation, the digestion process in cattle and sheep. It also includes emissions from fuel burned on-farm. These are the numbers that sit at the heart of most agricultural emissions reports.

Scope 2 is about purchased energy: the electricity you buy from the grid to run farm buildings, irrigation pumps or other infrastructure. Producers who generate their own solar power, or who run off-grid, often find their Scope 2 footprint is very low or close to zero.

Scope 3 is where it gets more relevant to your supply chain relationships. These are indirect emissions, things like the transport of livestock before purchase, or the embodied emissions in inputs like fertiliser.

Crucially, your total emissions also become the Scope 3 of every business downstream of you. The feedlot you sell to, the processor, the retailer, the bank that finances your property- all of them carry your emissions in their Scope 3 reporting.

This is the core reason why supply chains are asking producers for data. It has nothing to do with putting farms under pressure and everything to do with the fact that large businesses now have legal reporting obligations that require them to account for emissions all the way back through their supply chains. Australia's mandatory reporting laws will roll out from July 2025, starting with the largest businesses, and the Scope 3 requirement kicks in in year two of each business's reporting cycle. That means the pressure is real, it's arrived, and it's working its way down the chain.

The good news is that understanding your own numbers puts you in the driver's seat. Knowing where your emissions come from (and being able to share that information on your own terms) is a much stronger position than having someone estimate it for you.
