This analysis looks at the several Corporate Sustainability Reporting Tools (SRTs) that companies may use to measure and report on how well they are doing in terms of sustainability. The paper examines the efficacy, advantages, and drawbacks of key Sustainability Reporting Tools (SRTs), such as the Global Reporting Initiative (GRI), Sustainability Accounting Standards Board (SASB), and the Carbon Disclosure Project (CDP). The study shows how SRTs help firms talk about their environmental, social, and governance (ESG) implications by looking at how well these tools fit with global sustainability frameworks and how useful they are in different fields. The assessment also talks about new trends and future directions in sustainability reporting, such digitization and integrated reporting, that are changing how businesses are open about what they do. The results provide firms ideas on how to start or enhance their sustainability reporting
