The paper gives an analysis of values in environmental ethics. Attention is paid to the most important axiological theories, i. e. axiological individualism, resp. axiological holism. The author’s standpoint is, that a value theory corresponding the protection of environment could not be built on a subjective axiology, which makes the background of the above mentioned conceptions. In her view the concept of value results from human needs and from man’s struggle to survive. The concepts of „system value“, „transformative value“ are analysed as well. She is also concerned to show the relation between instrumental and intrinsic values.
