T/CCIIA 0010-2024 Greenhouse Gas Product Carbon Footprint Quantification Methods and Requirements for Chlor-Alkali Products

Scope

This document specifies the declaration units, system boundaries, inventory analysis, impact assessment, and carbon footprint reporting for the quantification of the carbon footprint of chlor-alkali products. This document is applicable to guiding the quantification of the carbon footprint of chlor-alkali products. Chlor-alkali products are produced by electrolysis of crude salt and combined with other raw materials to produce a series of products. The main products, such as caustic soda, hydrogen chloride, vinyl chloride, dichloroethane, and polyvinyl chloride, can be used as reference for carbon footprint quantification. This document only targets a single environmental impact type, namely climate change. It does not evaluate other potential environmental impacts generated during the product life cycle, nor does it evaluate the social and economic impacts that may occur during the product life cycle. The main technical contents of this standard include: Preface; Introduction; 1. Scope; 2. Normative referenced documents; 3. Terms and definitions; 4. Product category definitions and descriptions; 5. Purpose and scope of product carbon footprint quantification; 6. Inventory analysis; 7. Impact assessment of product carbon footprint; 8. Interpretation of product carbon footprint results; 9. Product carbon footprint report; Appendix
