Artificial intelligence is transforming how organizations connect with customers while simultaneously raising critical questions about environmental sustainability. This paper looks on how Artificial Intelligence Technologies that including chatbots, predictive analytics, recommendation engines, and real-time analytics are deployed across telecoms, banking and retail sectors, and also addressing the emerging imperative of sustainable AI practices. The paper highlights Airtel, Netflix, Amazon, and JPMorgan Chase usage of AI, illustrating both significant benefits and critical challenges of it. The findings of this paper reveal that AI works best when it doesn’t replace human judgement but instead complements them and when environmental accountability is embedded throughout the AI lifecycle. The paper throw light on problems like privacy concerns, algorithmic prejudice, over-automation risks, and the environmental impacts from energy consumption and carbon emissions. We have concluded that responsible AI-driven marketing requires transparency, clear governance, human oversight, investment in real-time analytics infrastructure, and commitment to green AI practices that balance innovation with environmental stewardship
