Short summary
Through reassessing the controlling variables and emission factors (EFs) of CH4 on a global scale, we find that the global default EF of CH4 is lower and has a narrow error range than the previous report. The region/country-specific EFs are for the first time developed. The findings of major controlling variables on CH4 emission may help to devise mitigation strategies at different scales. These default EFs and scaling factors can provide a sound basis for developing national CH4 inventories.
