Summary
This peer-reviewed study measured nitrous oxide emissions from cattle excreta under UK conditions and derived country-specific emission factors that differ from IPCC defaults. The findings suggest that UK national inventory calculations and carbon footprinting methodologies for ruminant livestock may require revision to reflect more accurate, locally-derived emission data. The research contributes to improving the precision of greenhouse gas accounting in agricultural systems.
UK applicability
The study was conducted in the United Kingdom and directly quantified UK-specific emission factors, making findings immediately applicable to UK national greenhouse gas inventory reporting and to carbon footprinting of British ruminant livestock products. The deviation from IPCC defaults has direct policy implications for UK climate reporting and livestock sector carbon accounting.
Key measures
Nitrous oxide (N₂O) emission factors from cattle urine and dung; comparison to IPCC default emission factors
Outcomes reported
The study quantified country-specific emission factors for nitrous oxide from cattle urine and dung, and compared these to IPCC defaults. The findings have direct implications for UK national greenhouse gas inventories and carbon footprinting of ruminant livestock products.
