The main purpose of this research study is to examine factors affecting the acceptance and
adoption of environmental management information systems in business organizations. Unified
Theory of Acceptance and Use of Technology (UTAUT) was employed in this preliminary
survey study. Its data were collected using questionnaires distributed to industrial companies
in 6 provinces within the northern region of Thailand, then were examined for convergent
validity and unidimensionality from 175 complete questionnaires through factor analysis,
and were confirmed for internal consistency reliability by means of Cronbach’s coefficient
alpha. After analyzing the relationship among factors using binary logistic regression, it was
found that only one factor, namely “Social Influence,”significantly related to adoption of
the systems in the organizations at the statistical level of 0.05.
