The growing importance of artificial intelligence (AI) has prompted work on the ethical issues raised by AI technology. We argue that environmental ethicists can make important contributions to AI ethics, and that doing so would be a worthy activity for environmental ethicists. Environmental ethicists can highlight the environmental dimensions of AI, such as its energy footprint and its potential application for environmental protection. Additionally, environmental ethicists can assess the ethics of novel situations that could be enabled by AI, such as computer-based artificial life and artificial ecosystems.
