Abstract
Agricultural sector emits large quantities of greenhouse gas, which is responsible for global warming. Some of the major greenhouse gases are methane, carbon dioxide, nitrous oxide etc. In our study, we have estimated the methane emission from beef cattle in Bangladesh. We followed the intergovernmental panel of climate change (IPCC) guidelines throughout our whole study. We used Tier 1 and Tier 2 methods for the calculation of methane emissions from beef cattle in Bangladesh. In the tier 1 method, we calculated the methane emission by using the emission factor provided by IPCC 2006 and 2019. According to IPCC 2019, we also calculated the methane emission using the tier 2 method which is based on dry matter intake. Finally, we have compared our calculated value. After calculation, in 2018, 2019, 2020 and 2021 total emission of methane from beef cattle based on Tier-1 (IPCC-2006) is 9990.00Gg, 10777.75Gg, 9996.75Gg and 10111.50Gg, respectively. Again based on IPCC-2019 emissions of methane are 17020.00Gg, 17169.50Gg, 17031.50Gg and 17227.00Gg, respectively. Using Tier 2 method (IPCC2019) methane emissions from beef cattle in 2018, 2019, 2020 and 2021 are 16087.60Gg, 16228.91Gg, 16098.47Gg and 16283.26Gg, respectively.
