Summary
This peer-reviewed research quantifies nitrous oxide emissions from cattle excreta under UK agricultural conditions, establishing country-specific emission factors that deviate from IPCC default assumptions. The work directly addresses the accuracy of UK national inventory reporting for ruminant livestock and enables more precise carbon footprinting of beef and dairy products. The findings suggest that tailored, context-specific emission factors improve the reliability of greenhouse gas accounting in national inventories.
UK applicability
The study provides empirically derived, UK-specific emission factors directly applicable to national greenhouse gas inventory calculations and livestock product carbon footprinting under UK conditions. These country-specific factors offer improved accuracy compared to generic IPCC defaults for UK farming systems.
Key measures
Nitrous oxide (N₂O) emissions from cattle urine and dung; country-specific emission factors (EFs) for the United Kingdom; comparison with IPCC default emission factors
Outcomes reported
The study quantified nitrous oxide emissions from cattle urine and dung under UK conditions and derived country-specific emission factors. The findings indicate that UK emission factors differ from IPCC default values, with implications for national greenhouse gas inventory accounting.
