城镇污水处理厂碳排放核算标准现状分析与比较

Current status of carbon emission accounting standards for urban sewage treatment plants

对国家温室气体排放核算方法标准和指南进行了系统梳理,发现国家层面缺乏城镇污水处理厂碳排放核算标准。对比了现行的6项涉及城镇污水处理厂的碳排放核算标准核算边界及核算因子存在的差异。目前的标准存在核算边界不统一、核算因子差异大等问题,建议下一步可进行行业统一的标准、规范的编制,并进行污水处理厂直接温室气体的监测,促进行业统一标准,此外,还需加强低碳技术的研发,促进行业低碳发展。

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 accounting standards for urban sewage plants at the national level.The accounting objects,accounting boundaries,and accounting scope is concluded for six current carbon emission accounting standards related to urban sewage plants.The current accounting methods have problems such as inconsistent accounting boundaries and differences in accounting factors.It is recommended that development 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 industry.
