ISO 20294:2018本文件规定了在用户知识和控制范围内量化电子媒体交付和使用所需的工艺、材料和技术的碳足迹的要求。它涵盖了对电子媒体存档、分发、使用和存储的要求。它基于生命周期评估（LCA）方法，使用定义的系统边界和指定的功能单元作为完整或部分碳足迹研究的基础。这些数据可以在各个电子媒体产品的整个供应链中引用
本文件适用于有关内容和电子媒体设备的电子媒体产品碳足迹（CFP）研究
本文件提供了一个组织可以遵循的碳计算器框架，可以用作市场或行业特定碳足迹工具的结构。 在该框架方法中构建的研究和工具提供了电子媒体的碳足迹量化，可以进行验证，并为未来的研究提供参考
本文件不评估产品生命周期可能产生的任何社会或经济方面或影响，或任何其他环境方面和相关影响。

ISO 20294:2018 This document specifies the requirements for quantifying the carbon footprint of those processes, materials and technologies within the user's knowledge and control that are necessary for the delivery and use of e-media. It covers requirements to account for e-media archiving, distribution, use and storage. It is based on a life cycle assessment (LCA) approach, using defined system boundaries and a specified functional unit as the basis for complete or partial carbon footprinting studies. These data can be referenced throughout supply chains for individual e-media products.
This document is applicable to a carbon footprint of a product (CFP) study of e-media regarding contents and e-media devices.
This document provides a framework for carbon calculators that organisations can follow and that can be used as the structure for market- or sector-specific carbon footprinting tools. Studies and tools constructed within this framework methodology provide carbon footprint quantifications of e-media that can be validated, verified and provide reference for future studies.
This document does not assess any social or economic aspects or impacts, or any other environmental aspects and related impacts potentially arising from the life cycle of a product.
