摘要
Abstract
In recent years,the carbon emission accounting of sewage treatment plants has received increasing attention.Accounting software based on LCA theory,such as SimaPro,GaBi and eBalance4.0,has a high degree of flexibility and visualization to customize assessment indicators and accurately analyze data.However,when the software is used for calculating the carbon footprint of municipal sewage treatment plants,the results are different due to differences in emission factors and databases.The result of the German accounting software GaBi is 0.18 kg CO2e/t higher than the Dutch accounting software Simapro and 1.65 kg CO2e/t higher than the Chinese accounting software eFootprint,mainly due to different database reference standards and material and energy emission factors.Therefore,it is important to choose the software suitable for the sewage treatment process and carefully choose the discharge factor.With the launch of the carbon border adjustment mechanism(CBAM)in October 2023,the selection of a carbon reporting reference database for the six industries is a new challenge.What's more,the standardization of the whole life cycle database is strengthened to provide a strong reference for the industry.关键词
