This study systematically reviewed the history and the art of state of data quality assessment (DQA). DQA was implemented basically based on pedigree matrices and conducted qualitative and quantitative evaluations on the basis of data quality indicators (DQIs). However, there were still such problems as unclear DQIs, inconsistent evaluation methods, and difficulties in quantitative evaluation etc. It was recognized that DQA research needed to be increased, and DQA processes, indicators, and methods suitable for the current data status of carbon footprint evaluation had to be constructed. Additionaly, much attention should be paid to data review and data documentation requirements, so as to provide guarantees for the development China carbon footprint database, as well as the implementation of LCA.
