Tools that can help with carbon footprint assessments
Ambitious carbon footprinting requirements from milk buyers are an opportunity to improve farm efficiency and road-test important environmental impact tools, farmers heard at Dairy Day this week (15 September).
Farms supplying major retailers will have to start producing carbon footprint assessments from April next year.
Kite Consulting’s John Allen said this was in response to the government’s net-zero target, which aims to slash national emissions by 78% by 2035 compared with 1990 levels.
Farms form part of supermarkets’ “scope three” emissions. Scope one includes direct emissions such as heating shops, and scope two is indirect emissions, such as travelling to work.
Mr Allen said some aligned farms had already submitted assessments for their milk buyers.
How to start out with carbon footprinting
- Engage with your milk buyer – if you are on an aligned contract, there is more chance there will be a system in place
- Ask if your milk buyer will help you
- Smaller dairies may rely on farms to instigate carbon footprinting themselves
- Start with good data to make assessments easier and more accurate – for example, fertiliser use, age at first calving, feed rate, what you are feeding (soya or rapemeal) and pregnancy rate
- Use the tool as an action plan to make improvements from a baseline and look to produce more milk and beef from fewer inputs

Addressing a packed climate seminar, livestock sustainability consultant Jude Capper told farmers there was no perfect carbon toolkit.

Shortcomings included an inability to manage two crops in a year (such as cover crops after oilseed rape) and big issues such as pasture being classed as a feed or not. But she encouraged farmers to road-test tools so developers could improve them.
“The more farms that use the tools, the more data that goes into the systems, the better road-tested they are – it’s a positive feedback cycle,” said Dr Capper.
She added: “Then we identify gaps and improve the science. We need an industry standard for carbon and, eventually, a global standard to compare us with New Zealand, Australia, Europe and the US. We should all be able to talk back at the myths – we must protect our industry.”
