Greenhouse Gas Product Carbon Footprint Quantification Methods and Requirements Lime

This standard outlines the methodological framework for quantifying and reporting product carbon footprints specifically within the cementitious materials sector, focusing on the production and lifecycle of lime. It establishes a unified approach to calculate greenhouse gas emissions associated with raw material extraction, energy consumption during manufacturing, and distribution processes. The document provides detailed instructions on setting system boundaries, selecting activity data, applying emission factors, and conducting life cycle inventory analysis for this specific industrial product. It addresses the calculation rules required to ensure consistency and comparability across different production facilities and supply chains. The methodology incorporates guidelines for handling upstream and downstream processes, aiming to support accurate assessment of environmental impacts throughout the product's life cycle. By defining specific calculation procedures and data quality requirements, this technical specification facilitates the transparent reporting of carbon emissions. It serves as a reference for organizations seeking to measure their environmental performance in the lime industry, enabling the identification of emission sources and opportunities for reduction strategies within the supply chain.
