<p>Artificial intelligence (AI)’s rapid advancement poses opportunities and challenges for environmental ethics. While AI has the potential to enhance ecological sustainability through data-driven solutions, it also risks depersonalizing ethical decision-making and reinforcing a technocratic paradigm that prioritizes efficiency over human dignity and environmental stewardship. This paper explores how Karol Wojtyła’s personalist philosophy provides a sound ethical framework for addressing these concerns. Personalism, which emphasizes the irreducibility of the human person, responsibility, and relationality, offers a foundation for rethinking environmental ethics in the AI era. This study supports a person-centered approach to environmental decision-making by including Wojtyła’s ideas on human agency, the common good, and ecological responsibility. Such an approach resists the reduction of human moral agency to algorithmic processes while fostering solidarity, subsidiarity, and ecological justice. Ultimately, this paper argues that a personalist environmental ethic can guide technological development toward serving humanity and the natural world, ensuring that AI remains a tool for sustainable and ethical progress rather than an autonomous arbiter of ecological fate.</p>
