Environmental, Social, and Governance (ESG) considerations have become increasingly critical in the development and assessment of national greenhouse gas inventories. This document aims to provide comprehensive guidance on implementing Quality Assurance (QA), Quality Control (QC), and verification procedures as outlined in the 2006 IPCC Guidelines for National Greenhouse Gas Inventories. The primary objective is to ensure that national inventories are transparent, consistent, comparable, complete, and accurate, thereby supporting global efforts to mitigate climate change. Readers will find detailed answers to key questions such as: What are the essential elements of a QA/QC and verification system? How can practical considerations be balanced with technical requirements in developing these systems? What roles and responsibilities should be defined to ensure effective implementation? Additionally, the document delves into specific QA/QC procedures for various categories, including emissions factors, activity data, and calculation-related checks, as well as the importance of documentation, archiving, and reporting. By the end of this document, readers will have a clear understanding of the methodologies and best practices for QA/QC and verification in greenhouse gas inventory development. They will be equipped with the knowledge to implement these procedures effectively, ensuring the reliability and credibility of their national inventories. This understanding will enable them to make informed decisions about whether to adopt the guidelines and practices discussed herein. This introduction sets the stage for a detailed exploration of QA/QC and verification processes, helping readers decide if the document aligns with their needs and interests in enhancing the quality of greenhouse gas inventories.
