The multivariate relationship between environmental attitudes and pro-
environmental behaviour was examined. In two studies a structural mode
l linking environmental awareness, emotions, personal-philosophical va
lues, perceived control and behaviour was proposed and tested. The mai
n questions investigated were (a) whether, to what extent, and in whic
h constellation personal belief systems affect environmental behaviour
, and (b) the generalizability of the model from two known groups. New
instruments were created to measure the model's constructs. Using LIS
REL VII, Study I confirmed the proposed model. The strongest effect on
environmental behaviour stemmed from personal-philosophical values an
d emotions. No effects on environmental behaviour stemming from factua
l knowledge were found. Thirty-nine per cent of the variance in enviro
nmental behaviour was explained by the attitudinal components. Study I
I showed the extent to which persons differ in their environmental beh
aviour depending on their membership in a 'green' drivers' association
, compared with traditional drivers. (C) 1995 Academic Press Limited
