Scope: This document reviews the typical process flow of graphene preparation by industrial arc method, 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 paths, recommends best practices for green preparation and potential technologies and carbon reduction suggestions, and provides a template reference for enterprise accounting. This document provides guidance on reducing, recycling, and reusing materials, as well as harmless processing 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: In 2020, China solemnly pledged to the world that China's carbon dioxide emissions would peak by 2030 and strive to achieve carbon neutrality by 2060. The goal of "peaking carbon emissions by 2030 and achieving carbon neutrality by 2060" will undoubtedly have a significant and practical impact on the development of all industries in China. In 2021, the National Standardization Development Outline issued by the Central Committee of the Communist Party of China and the State Council pointed out that: Improve the standardization guarantee for green development, establish and improve standards for carbon peaking and carbon neutrality, and lay a solid foundation for green production standards. It can be seen that green processes, green technologies, and green development are the future development direction of the industry, which can ensure the stable and long-term development of the industry. As a new carbon-related nanomaterial, graphene materials have multiple excellent intrinsic properties and broad application prospects in new energy, thermal management, 5G and electronic devices, power grids, aerospace, rail transportation, automobiles, military equipment, sports equip
