A systematic review of national greenhouse gas emission accounting standards and guidelines has been conducted,and it has been found that there is a lack of carbon emission ac-counting standards for urban sewage plants at the national level.The accounting objects,account-ing boundaries,and accounting scope is concluded for six current carbon emission accounting stand-ards related to urban sewage plants.The current accounting methods have problems such as incon-sistent accounting boundaries and differences in accounting factors.It is recommended that devel-opment industry unified standards and regulations,monitor greenhouse gases directly from sewage treatment plants to promote industry standardization.In addition,it is necessary to strengthen the research and development of low-carbon technologies to promote low-carbon development in the in-dustry.
