Environmental friendliness and environmentally friendly behaviour are an important issue in Estonia and all over the world because the environmental scholars are continuously worried about environment conditions. The human behaviour is one of the reasons why environmental problems are raising. Environmental concern is a concept, which is widely used in environmental psychology literature. This concept is often seen as one of the attitudinal mediators, which leads to environmentally friendly behaviour. The environmentally friendly behaviour might also be seen as moral behaviour, where the person should sometimes act against his/her personal interests.The present work is based on P. W. Schultz’s theory about egoistic, social-altruistic and biospheric environmental concerns. P. W. Schultz, relying on theory of norm-activation by S. Schwartz (1977) and expanded norm-activation theory in environmental psychology (Stern, Dietz & Kalof, 1993) supposed that environmental concern (an attitude) is based on belief of harmful consequences for the valued objects. Schultz (2000) proposes that these valued objects can be classified as self, other people or other living things. He calls these concerns as egoistic, social-altruistic or biospheric environmental concerns. Schultz claims that these three concerns are not definitely distinct so that egoistically concerned people could be as environmentally concerned as people holding altruistic or biospheric concerns. Still the biospherically oriented person could be concerned about environmental problems far away from their home and so the biospheric concern provide a broader motive for behavior. The people holding more egoistic concern should have had less contact with natural environments than people having other types of concerns.The aim of this study was to test Schultz’s environmental concerns theory an Estonian sample and control a hypothesis about the behavioural connections with nature and the attitudinal bases of environmentally friendly behaviour. Estonia is rather small country with 1,4 million inhabitants and the biggest city is the capital Tallinn with 400 000 inhabitants. The structured questionnaire “Environment and us” was conducted by the Tallinn Pedagogical University’s Environmental Psychology Research Unit in 2002. Several questions about various aspects of social life, environmental concern and values, environmental friendliness, behavioural intentions, and beliefs were asked.The sample of this study consisted of 687 Estonians, of which 54 % were women. The age of respondents ranged from 15 – 80. For hypothesis testing the factor analysis, descriptive statistics and t-tests were used.Two highly correlated factors appeared which were named egoistic and altruistic-biospheric concerns to the environment. The valued objects of natural environment did not form separated factor. Based on the percentiles I divided respondents into two groups: more egoistically (constituting 12% of all respondents) and more altruistic-biospherically (constituting 16 % of all respondents) environmentally concerned. The more altruistic-biospherically concerned people did not have more connections with nature (they were not living more in the country side or small towns, they did not have more domestic animals or pets and did not have more summerhouses or owned more land than the more egoistically concerned respondents). According to the theory the egoistically and altruistic-biospherically concerned respondents did not differ in evaluating environmental problems in close environment. But more egoistically concerned evaluated the environment conditions in the whole world better than the altruistic-biospherically concerned did. The egoistically concerned people were more optimistic and thought that each individual can take more action for environment compared to the altruistic-biospherically concerned. The altruistic-biospherically concerned had higher scores in environmentally friendly behaviour intention scale, which means that their willingness to take an environmentally friendly action is higher. Interestingly the more altruistic-biospherically environmentally concerned people had more emotional connection with nature and valued higher the inner beauty of nature.The results showed that the altruistic-biospheric concern for the consequences for other people and natural environment is more important indicator for environmentally friendly behaviour, but more altruistic-biospherically concerned did not have more connections with nature. In seems that Estonians` environmental concern is not influenced by their place of residence, maybe because many Estonians have still grandparents living in the county-side or they own land there. The difference being more egoistically or altruistic-biospherically concerned is rather based on other indicators like emotional connection, admiring and observing nature. Maybe the psychological factors are better indicators of different types of environmental concern than the actual time spent in nature.
