Artificial Intelligence (AI) has emerged as a change agent in different sectors, with both great opportunities and challenges for the area of sustainable development. This paper examines the dimensions of AI technologies and SDGs, focusing more on how AI can make resource efficiency better, equitable economic growth greater, and environmental stewardship easier. For each of renewable energy, waste management, and climate resilience, we consider a case study to illustrate how AI can contribute to process optimization and the reduction of emissions; on the other hand, we briefly mention some of the challenges regarding fair access to AI benefits, including the issue of bias in AI algorithms and the digital divide. Overall, the finding here suggests that AI should hold important potential in advancing sustainability to be usable but requires collaborative involvement of policymakers, technologists, and communities to ensure that AI contributes to inclusive and sustainable outcomes. Above all, this paper calls for a balanced integration of AI into sustainability policy for continued research, regulation, and engagement with stakeholders to navigate the dynamic complexities of the field.
