The driving force of civilizational change was and is the development of science, education, and great ideas that determine human actions, shaping the attitudes and behavior of individuals, organizations, and entire societies. Such an idea is sustainable development, an anticipation of the possible future challenges of society, so knowledge about it should be communicated to a wide audience because action is possible when various entities have the appropriate knowledge. Implementing the concept of a sustainable organization requires an organization to change its mindset (testing existing principles, beliefs, or behaviors) and to take steps to build an organizational culture so that the idea of sustainability applies to all levels in the organization, i.e., jobs, processes, and strategies. The changes should go in the long-term direction, not just be short-term actions. What is needed, then, is a deep analysis of existing resources and an understanding that the organization does not operate in a vacuum, but interacts with the natural environment, the local community, employees, shareholders, and stakeholders. The purpose of the article is to identify ways to implement the concept of sustainability through knowledge management using an e-learning platform in the relationship ecosystem using the example of the chemical company ‘Grupa Azoty’ Group. A case study method was used, which allowed the analysis of the issue of sustainable development in the context of knowledge management and corporate e-learning. In addition, an analysis of the state and prospects of the chemical industry in Poland during the period of sustainable transformation as a business environment for ‘Grupa Azoty’ Group was carried out. For the described company, the development and implementation of an e-learning platform can support the implementation of a sustainable development strategy.
