Scope

This document specifies the terms and definitions for the carbon footprint quantification of chlor-alkali products (hereinafter referred to as the products), product types and descriptions, objectives and scope, inventory analysis, impact assessment, result interpretation, and product carbon footprint reports, etc. This document is applicable to guiding the carbon footprint quantification activities of a single environmental impact type (climate change) and a series of chlor-alkali products derived from the electrolysis of raw salt and other raw materials. It is not applicable to other potential environmental impacts generated during the product life cycle or the social and economic impacts that may arise during the product life cycle. The carbon footprint quantification activities of products such as caustic soda, hydrogen chloride, vinyl chloride, dichloroethane, and polyvinyl chloride can be used as reference.
