The paper studies the attitudes of consumers of Maharashtra toward organic food, in particular related to their concerns about the environment and sustainable development and the impact on their purchasing behavior. It studies the relationship of demographic parameters such as age, gender, and education level to several variables, including organic food buying frequency, reasons for the purchase of organic food, and knowledge of the meaning of environment-related certificates. The number of participants in the study was 190 people from three tahsils of Thane district, Maharashtra. The results show that the opinions and behavior of customers are very diverse, but, for most, the attitude to sustainable development plays an important role in terms of buying organic food.
