The line of investigation on the environmental attitudes has been able to count on an ample tradition of environmental psychology. In this work, the research adopts a particular way, since the state organisations and industry, be they pollutant or not, seek to analyse the pro-environmental attitudes of the workers, whose results facilitate information which serves as a basis for the preparation of intervention and allows for the planning of the most appropriate actions, such as making conjectures as to the aspects of the proposed model upon which the formative action, which forms part of our programme, should be constructed.We will try to throw some light on the questions of what motivates a pro-environmental behaviour or which are the determiners of responsible ecological behaviour.
