Across the livestock sector, one part of farm greenhouse gas footprints has traditionally been left out: the emissions embedded in purchased animals. These “upstream” emissions, produced while an animal is raised on another farm, are a real part of supply‑chain climate impact, yet they’ve been inconsistently accounted for across tools and standards.
At Cool Farm, we’ve worked with Agrecalc, Farm Carbon Toolkit, and Eggbase and introduced a practical, robust, and internationally aligned method to include embedded emissions from purchased livestock in the Cool Farm Platform. This brings us in line with the GHG Protocol, IDF and PEF guidance, and helps close a long‑standing transparency gap in livestock footprints.
Why this matters
Farms that raise their own replacements and farms that buy them in should be assessed on a level playing field. Omitting embedded emissions can underestimate footprints for some systems and distort comparisons. By including them, we create a fairer, clearer picture of climate impact, and highlight real opportunities for improvement across the supply chain.
How the new Cool Farm method works
Our approach has been live since Nov 2025 in Cool Farm Platform 3.0 (https://cfp.coolfarm.org/) and is intentionally simple and consistent with the rest of the Cool Farm cattle logic:
✅ Uses internationally recognised FAO GLEAM emission factors
Mapped to global regions and expressed per kg liveweight, these factors already include all relevant animal emissions (enteric, manure, feed, energy, land‑use change) using AR6 GWP values.
✅ Applies emissions to each purchased animal based on user‑entered weight and numbers
The calculation follows the method described in our technical documentation:
Purchased livestock emissions = emission factor × liveweight × number of animals.
✅ Fits easily within existing Cool Farm workflows
Users only need to enter the cattle they bought in that year; they can add purchase weights if known, or rely on our defaults; the tool handles the rest.
What this means for farmers and supply chains
Including embedded emissions won’t change management on the ground overnight, but it will:
- Improve the completeness of farm footprints
- Provide clearer comparisons between different livestock systems
- Support more credible reporting for supply-chain climate commitments
- Help spotlight where emissions reductions can happen upstream, and encourage custom emission factors for purchased animals.
The effect varies by enterprise. In some systems the change is small (e.g., day‑old poultry example in Farm Carbon Toolkit), while in others, such as dairy or beef farms purchasing replacements, the improvement in boundary coverage and overall completeness is more significant.
Looking ahead
This update is just the first step. As more suppliers begin reporting verified emissions for their youngstock, we would like to support custom factors and greater data transparency over time.
For now, we’re pleased to bring a well‑grounded, harmonised approach into the Cool Farm Platform—one that helps the whole sector move toward clearer, more complete climate reporting.
