A major new study published in the Journal of Cleaner Production has assessed the climate impacts of nearly 1,000 UK dog foods. The largest and most detailed analysis of its kind, it finds over a 65-fold difference in impacts across feeding approaches—and shows that dogs fed premium, meat-rich diets can have a larger dietary carbon pawprint than their owners. Nationally, the study estimates dog food contributes around 0.9–1.3% of total UK greenhouse gas emissions.

This article explains why meat in pet food can be high-impact—especially when it uses human‑edible “prime” meat—while animal by‑products may be lower-impact if they would otherwise be wasted. It also shows that different methods of allocating emissions between prime cuts and by‑products can dramatically change sustainability comparisons across pet-food types and alternative proteins.

Food-system emissions moved up the political at COP28. This article, written for a pet food industry publication, discusses that sustainability claims remain hard to compare because impact estimates vary widely, strengthening the case for clearer labelling and standardised metrics.
