In recent years, social media has emerged as a powerful medium for promoting and achieving Sustainable Development Goals (SDGs). This paper explores the multifaceted role of social media applications in advancing the 17 SDGs outlined by the United Nations. By analyzing literatures, user engagement metrics, and usage strategies, we aim to understand how social media can drive awareness, mobilize communities, and foster collaboration among stakeholders. The study identifies key platforms and tactics that have proven effective in influencing public opinion, disseminating critical information, and key purpose for using social media toward sustainability. Furthermore, it highlights the challenges of applications, digital divide, and correlation among different sustainable goals (Quality Education, Good Health and Well Being, Sustainable Communities, Climate Action) concerns that could undermine these efforts. Our findings suggest that when strategically leveraged, social media not only enhances communication and outreach but also accelerates the implementation of sustainable practices globally. However, there are total sample taken for study is 500 out of which 466 have been collected, it includes descriptive study with survey method to collect responses. This paper concludes with recommendations for policymakers, NGOs, and social media companies to utilize the full potential of these digital platforms in achieving a more sustainable future.
