Penelitian ini bertujuan untuk mengevaluasi konversi produksi daging sapi potong terhadap emisi metana di Kabupaten Semarang berdasarkan data populasi dan produksi daging. Emisi metana dihitung menggunakan metode tier 1. Data populasi sapi potong dan produksi daging sapi di Kabupaten Semarang dari tahun 2015-2019 digunakan untuk menghitung konversi produksi daging dari sapi potong terhadap emisi metana. Populasi sapi potong jantan dewasa di Kabupaten Semarang dari tahun 2015-2018 mengalami penurunan secara berurutan menurun sebanyak 10,3%, 1,3%, 1,8% dan meningkat Kembali tahun 2019. Produksi daging menurun pada tahun 2016-2018, secara berurutan menurun sebesar 11,42%, 0,30% dan 1,95%. Pada tahun 2019 produksi daging meningkat sebesar 7,04%. Produktivitas tertinggi terdapat pada tahun 2015 (163,86 kg/ekor). Emisi metana dari fermentasi enterik dan pengelolaan kotoran ternak pada tahun 2015-2018 menunjukkan penurunan, danmeningkat pada tahun 2019. Rata-rata emisi metana dari fermentasi enterik yaitu 0,466 Gg CH4/tahun, sedangkan dari pengelolaan limbah kotoran yaitu 0,009917 Gg CH4/tahun.Rata-rata produksi daging sapi potong per cemaran metana yang dihasikan di Kabupaten Semarang sebesar 1,94-7.Angka konversi terbaik di tunjukkan pada tahun 2018 adalah sebesar 1,42-7.Dapat disimpulkan,meskipun jumlah populasi ternak menurun sedangkan produktivitas ternak ditingkatkan maka produksi daging akan meningkat, sehingga emisi metan per produksi daging dapat diturunkan.
