How do teachers support sustainable development in modern didactic process?

Sustainable development, in all of its aspects, is possible to be achieved only thanks to properly planned and effectively implemented formal, informal and non-formal education. In this context, what teachers know about sustainable development, to what extend they know its assumptions and demands, and how they implement these assumptions in their everyday school practice is extremely important. I will present the results of research concerning teachers' knowledge regarding education for sustainable development, the didactic methods and forms which they apply while implementing the didactic process for sustainable development.
