Get to know all the advantages of the 02 project
Our socially responsible project O2 - Education for sustainability offers free educational materials and applications

The advantages of lifelong learning and investing in knowledge are many. While on the one hand an individual increases competitiveness on the labor market, on the other hand he strengthens self-confidence, develops creativity and improves and adopts communication skills, as well as many other skills such as financial or digital literacy. Lifelong learning is also a response to global changes and rapid technological development and changes in the labor market, therefore it is extremely important to invest in one's own knowledge and education throughout one's life in order to achieve social sustainability.
Along with various educational institutions that provide experts, resources and programs for lifelong learning, citizens as individuals are extremely important in the whole process. Namely, they are the main bearers of ideas, information and new knowledge and skills with which they simultaneously improve themselves and the economic system of the society they are a part of, at the same time representing drivers of social change.
Callidus is a leading institution for adult education and in its work is dedicated to the systematic improvement of the category of lifelong education, which represents the path towards the sustainability of society.
Through our socially responsible project "O2 - Through education to sustainability", we enable citizens to use various educational and innovative materials and applications that have resulted from our work on EU projects for free. These programs help people acquire new, but also develop existing competencies in order to raise the quality of their life in the family and community.
