The precision of a prediction about the future environment inside a greenhouse is improved with the cost of installation, maintenance, and the like of a sensor being reduced. An information processing device including: a predicting unit that predicts the environment inside a greenhouse based on weather prediction information by using a greenhouse inside-environment prediction model which is obtained by machine learning that is performed based on actual result information on the environment inside the greenhouse by using weather observation information as input； and an output control unit that controls output of prediction information on the predicted environment inside the greenhouse is provided.
