Commuters' concern for the environment and knowledge of the effects of vehicle emissions.

Attitudes towards the environment and knowledge of the polluting effects of vehicle emissions were surveyed in 566 train and bus commuters, private motor vehicle commuters and smoky vehicle commuters. Environmental concern was found to significantly correlate with level of contribution to an environmental organisation but not with levels of environmental attitudes or emissions knowledge. Smoky vehicle drivers did not have lower levels of knowledge of emissions or lower levels of environmental concern compared to other private motor vehicle commuters. Train commuters showed no greater concern for the environment than car commuters. (A) "Reprinted with permission from Elsevier".
