T/JSAS 089-2025 Greenhouse gas—Quantification method and requirements for carbon footprint of products—Phosphatic fertilizer

Scope

This document specifies the purpose, scope of quantification, inventory analysis, impact assessment, interpretation of results, product carbon footprint report, and product carbon footprint declaration of phosphate fertilizer products. This document is applicable to the quantification of phosphate fertilizer products. For the quantification of other similar products, this document can be used as a reference. 6.1.2 Data Collection Principles The following principles should be followed when collecting product data: a) Where the organization conducting the product carbon footprint study has financial or operational control over the product, on-site data should be collected. The collected process data should be representative. For the most important unit processes, such as those accounting for more than 50% of the product's carbon footprint, even without financial or operational control, on-site data should be used. b) Where on-site data collection is not feasible, primary data from third-party-reviewed off-site sources should be used. c) Only when primary data collection is not feasible, or for less important processes, can secondary data be used. d) For greenhouse gas emissions and removal factors in secondary data, national authoritative carbon footprint factors should be prioritized. Factors with geographical, temporal, and technological representativeness should be selected to quantify the product's carbon footprint. e) Evaluate the data quality of direct emission data, energy and raw material usage data, and greenhouse gas emission factors. f) Collect higher-quality data to improve data quality. g) Carbon offsetting is not allowed during the quantification phase of the product carbon footprint. The data collection table for product carbon footprint quantification is shown in Appendix A. 6.1.3 Data Collection Requirements Primary data corresponding to the collection items include: a) Consumption of main materials (phosphate rock, inorgan
