ABSTRACT To support national estimates of methane (CH 4 ) emissions from manure management systems, the Intergovernmental Panel on Climate Change (IPCC) proposed guidelines that include three tiers, which Tier 1 and 2 methodologies are most used. The choice each methodology is often driven by data availability. application IPCC approach uses default emission factors requires less compared to 2, considered a more advanced methodology. Nevertheless, no study has addressed implications estimation CH swine systems. Subsequently, there barely any quantitative information discrepancies expect when using or for estimating significant sources such as open‐air waste treatment lagoons. Hence, this used estimate feeder‐to‐finish lagoons across North Carolina region. Precisely, updated were applied farm, county, state level farms quantify anaerobic Results show 2's higher, sustaining discrepancy 6.7% between two Tiers’ methodologies. Quantitatively, differences tiers’ totaled 7320 Mg /year (197640 CO equivalent/year) at unequally distributed among counties farms. comparative analysis highlighted meaningful contrast Tiers per head unit animal weight direct measurements lagoons’ in Carolina. likely due large part errors measurements, suggesting need techniques situ measurements. highlights trade‐off related approaches, reported could be useful better understand inventories.
