ABSTRACT
This chapter deals with the issue of Green Information Technology (Green IT) in companies. It explains this phenomenon in detail and emphasizes the fact that Green IT is synonymous with sustainable development in the production and use process. The chapter analyzes the phenomenon of Green IT applications in Polish companies that have developed agility, which is a characteristic feature of Teal organizations. Sustainable development is always linked to the need to implement economic, social, and environmental standards of the highest quality, which must reflect the capacity of ecosystems. Ecological development can therefore be understood in the broadest sense as the greening of all operational processes, while at the same time attempting to meet the expectations of the individual stakeholders, i.e., the financial expectations of the owners and shareholders, the need for stability for employees and the need for security. Turbulent market conditions make it necessary to increase the importance of responsible management.
