After reading the document, readers will understand the methodologies for calculating emissions across 15 distinct Scope 3 categories, the types of data required, and the emission factors to be used. They will also gain insights into the importance of data quality, the use of primary and secondary data, and the iterative process of improving data accuracy over time. The guidance includes practical examples and decision trees to help companies select the most appropriate calculation methods based on their specific circumstances and data availability. This introduction aims to provide a clear overview of the document's purpose and content, enabling readers to decide if it meets their needs for understanding and managing Scope 3 emissions.
