The objective of this article is to weave hermeneutic considerations and philosophies concerning ethics, economy and climate, with a specific focus on the relationship between Kant's categorical imperative and the question of improved sustainability. The economic perspective of Georgescu-Roegen has been considered, to this end. Although economy, ethics and biology constitute distinct fields of specialization, this work seeks to show reasons for which this perspective could be seen as an intersection between the three disciplines. The article concludes with the message of Georgescu-Roegan, held in his saying “minimal bioeconomic program” in accordance with the fundamental precepts of the Kantian ethics, in respect to the question of sustainability.
