Method for establishing life cycle evaluation database

Abstract

The invention provides a method for establishing a life cycle evaluation database, and belongs to the field of life cycle evaluation databases. The method comprises the steps of formatting the unit process list initial data according to a life cycle evaluation database data standard to obtain unit process list data corresponding to an enterprise production and consumption process; encoding the unit process list data corresponding to the enterprise production and consumption process by using an industry classification standard to obtain source data of industry-level life cycle evaluation database construction corresponding to multiple industries; obtaining average unit process list data corresponding to the enterprise production and consumption process in the industry by utilizing the source data; and associating the identification directory with the average unit process list data corresponding to the enterprise production and consumption process in the industry to obtain a life cycle evaluation database. By automatically optimizing the life cycle evaluation database, the effectiveness of environmental impact evaluation and the potential value of the life cycle evaluation database are improved.

Description

Technical field [0001] The present invention relates to the field of life cycle evaluation database, in particular to a method of establishing a lifecycle evaluation database. Background technique [0002] Life cycle evaluation (LCA) is a environmental impact assessment method for universal applications at home and abroad. Such an environmental impact assessment method is a data-intensive method that requires a large amount of background data. These background data are mainly derived from international authority lifecycle evaluation databases. However, this database is usually measured by the professional line, calculated, time consuming, and high data uncertainty. At present, the mainstream lifecycle evaluation database is mainly from US Europe, and other countries have rarely establish a complete, high-quality lifecycle evaluation database. Using foreign life cycle evaluation databases is difficult to carry out localized accurate environmental impact assessments, leading to urg...

AI Technical Summary

Problems solved by technology

[0005] It can be seen that there is currently little focus on the automatic construction of localized life cycle assessment databases, and it mainly relies on several existing foreign life cycle assessment databases, which greatly limits the effectiveness of environmental impact assessment and the potential of life cycle assessment databases. value, it is extremely urgent to explore an automated, high-quality, low-cost life cycle assessment database construction and management method
