Summary
This study presents quantified, country-specific emission factors for nitrous oxide arising from cattle urine and dung in United Kingdom conditions. The research indicates that UK-derived factors differ from IPCC defaults, with direct consequences for the accuracy of national greenhouse gas inventories and the carbon footprint assessments of UK ruminant livestock products.
UK applicability
The findings are directly applicable to UK agricultural policy and national climate reporting, suggesting that current IPCC default emission factors may not accurately represent UK conditions and that inventory methodologies may require revision to better reflect domestic livestock production systems.
Key measures
Nitrous oxide (N₂O) emission factors from cattle urine and dung; comparison with IPCC default emission factors
Outcomes reported
The study quantified country-specific emission factors for nitrous oxide from cattle urine and dung, and compared these against IPCC default values. The findings have implications for revising the UK's national greenhouse gas inventory and for carbon footprinting of ruminant livestock products.
