University campus is a huge carbon emission unit, and accurate carbon emission calculation is the basis for moving towards carbon neutrality, but there are still many deficiencies in the current calculation system of university campus carbon emission calculation. In order to further elucidate the carbon emission calculation of university campuses, the study relies on mainstream databases to sort out the existing research results of carbon emission calculation of university campuses through literature analysis and summarization, and summarizes and analyzes them in terms of the calculation system and calculation results, pointing out the shortcomings of the current research and indicating the possible research directions in the future, so as to provide valuable references for the calculation of carbon emission of university campuses and promote the construction of carbon neutrality of university campuses.First of all, the study summarizes the current standards and practices of carbon emissions from university campuses, and points out that compared with the macro-level national or regional level and the micro-level of building units, university campuses are more functional, densely populated, and equipped with special sources of carbon emissions, such as scientific research activities. As a carbon reduction space at the meso-community level, its carbon emission sources are similar to those of the community, and the calculation method also follows the mainstream carbon emission calculation system. However, the current research on carbon emissions from university campuses has not adopted a relatively unified methodology, which still needs to be further improved.Secondly, literature search and analysis were carried out in the CNKI and Web of Science databases, and at the same time, relevant standards, guidelines and practice cases were also included in the scope of review. It is found that the literature mainly focuses on four aspects: carbon emission calculation of university campuses, summarization and analysis of carbon emission characteristics of university campuses, carbon neutral pathway and carbon neutral assessment of university campuses, and the complete carbon emission calculation system of university campuses includes the calculation boundary, classification of emission sources, calculation method, and the way of obtaining calculation data, and the calculation results are then derived. The summary and analysis of the literature in terms of the calculation system and the calculation results show that the current research is inconsistent and incomplete in the statistics of carbon emission sources in university campuses, especially the Scope 3 carbon emission which plays a key role in carbon neutrality has not been paid attention to, and it also points out the room for improvement of the calculation precision and intelligence, as well as the shortcomings of the construction of the calculation model.Finally, the study proposes that university campuses need to establish a standardized calculation framework for carbon emissions on university campuses, and standardize the list of emission sources and the calculation process. In terms of calculation accuracy and lack of intelligence, although hybrid calculation methods can appropriately improve the calculation accuracy, the application of intelligent technology tools in data acquisition, calculation processing, analysis, etc. and the refinement and improvement of the accuracy of emission factors are still quite important. Moreover, it is necessary to construct a full life cycle carbon emission calculation method for university campuses, and study thecalculation method that adapts to the needs of multiple scenarios such as pre-design. A more complete system for carbon emission calculation on university campuses must be established to meet different needs, promote the carbon neutral construction of university campuses, and lead the low-carbon development of the neighboring regions and the whole society.
