Scope: This document reviews the typical process flow of industrial preparation of graphene oxide, lists the consumption ranges of key factors such as raw materials and energy consumption, organizes the greenhouse gas emission accounting methods of typical processes, proposes green preparation pathways, recommends best practices and potential technologies for green preparation, and provides a template reference for enterprise ledgers. This document provides guidelines for reduction, resource utilization, and reuse, as well as harmless treatment in the manufacturing process of graphene materials. This document is applicable to green park planning, green plant construction, green process evaluation, and green investment decision-making, etc. Main technical content: This standard defines the concept of "green preparation" from the aspects of material and energy reduction, resource utilization, reuse, and harmless treatment. By analyzing the energy and resource consumption during the typical preparation process of graphene oxide, the key factors affecting greening are identified. Based on the analysis of these key factors, through extensive research, literature review, patent analysis, report review, and production practice surveys, best practices and potential green technologies are specifically proposed, providing reference and guidance for the design of green production lines, improvement of green processes, and evaluation of green processes in graphene enterprises. At the same time, this document references the national standard for greenhouse gas emission accounting in chemical enterprises, and combines the characteristics of graphene oxide preparation to summarize the specific method of greenhouse gas emission accounting during the preparation process of graphene oxide and provide suggestions for enterprise ledgers. It provides a method for enterprises to achieve their own carbon emission management and self-evaluation, and proposes enterprise carbon management
