Comparison of methodologies for estimating enteric methane emission factors from sheep in smallholder systems in Africa: A case study from Ethiopia por Gurmu, E.B., Ndung’u, Phyllis, Wilkes, A., Getahun, D., Graham, Michael, Leitner, Sonja, Marquardt, Svenja, Mulat, Daniel, Merbold, Lutz, Worku, Tigist, Gakige, Jesse K., Tadesse, D., Bekele, M., Arndt, Claudia

“…Based on the findings, we can say that variations in EF values emphasize the significance of taking different Tier 2 approaches into account when evaluating and comparing CH4 emissions estimates in smallholder sheep farming systems. However, there is a need for further investigations to compare the two Tier 2 methodologies against actual intake and emission measurements to decide which methodology is better.…”
