T/JSAS 095-2025 Greenhouse gas—Quantification requirement and method of product carbon footprint —Steel wire ropes

Scope

This document specifies the purpose and scope of quantifying the carbon footprint of steel wire ropes, inventory analysis, impact assessment, interpretation of results, methods for preparing steel wire rope carbon footprint reports, and product carbon footprint declarations. This document applies to the quantification of the carbon footprint of steel wire ropes defined in GB/T 8706. Note: This document only addresses a single impact type, namely climate change, and does not evaluate other potential environmental impacts of the product life cycle or the social and economic impacts that may arise during the product life cycle. 6.1.2 Data Collection and Verification Steps The data collection and quality assessment for the carbon footprint of steel wire ropes (see Appendix A) should follow the following steps: a) Define the scope of data collection to cover all unit processes within the system boundary; b) Collect qualitative and quantitative data included in the inventory to quantify the inputs and outputs of unit processes; c) Conduct data validation during the data collection process by establishing quality balances, energy balances, and/or comparative analyses of emission factors; d) Relate the input and output data of the system boundary to the declaration unit, primarily involving primary and/or secondary data; e) Record detailed information about data sources and conduct data quality assessments using the method described in Appendix B. 6.1.3 Primary Data Collection Data on the acquisition of raw materials, auxiliary materials, and energy for steel wire rope production, as well as activities during the product manufacturing and distribution phases, should be collected as primary data whenever possible: including all known inputs and outputs of unit processes within the system boundary of the steel wire rope. Inputs refer to consumed raw materials, energy, auxiliary materials, packaging materials, and water. Outputs refer to products, by-pro
