Technological innovation has enormous potential to promote a more socially and economically responsible industry. By reducing the environmental impact of various activities and festivals and increase sustainability. This paper explores the role of technology in promoting sustainable practices in event management from resource optimization to audience engagement. Key innovations include digital ticketing, waste management sensors, energy-saving lighting and real-time crowd management system to reduce material loss, power consumption and logistical inefficiencies. Digital tools such as virtual reality (VR) and hybrid event platforms, allows for remote participation, which reduces extensive travel and associated carbon emissions. However, there are also challenges in integrating these technologies. High-cost Data privacy concerns and the need for skilled employees can create obstacles especially for small events. Additionally, the environmental impact of digital infrastructure, such as server power consumption, it must be carefully considered to avoid undesirable consequences. This paper highlights best practices for overcoming obstacles in technology adoption, including partnerships with eco-focused tech providers and implementing data-driven sustainability metrics. The study concludes that meanwhile, technological solutions can greatly enhance sustainability of various activities and festivals, a balanced approach that takes into account ecological impacts and practical feasibility is essential. Developing industry-wide standards and promoting collaboration among stakeholders can further promote sustainable innovation, ensuring that various events and festivals contribute positively to environmental goals while delivering memorable experiences
