Abstract

The Greenhouse Gas Protocol (GHGP) serves as the global standard for measuring and reporting greenhouse gas (GHG) emissions, guiding organizations in their sustainability efforts. This paper examines case studies from industry leaders across various sectors to highlight best practices, challenges, and innovative solutions in GHGP implementation. Key findings reveal how companies successfully navigate Scope 1, Scope 2, and Scope 3 emissions reporting, integrate digital monitoring technologies, and enhance transparency through third-party verification. The case studies underscore the importance of regulatory alignment, corporate commitment, and stakeholder engagement in achieving credible and effective emissions reporting. By analyzing these real-world applications, this study provides valuable insights into optimizing GHGP adoption for improved environmental performance and compliance with climate policies.
