We examined attitudes as one potential influence on the behavioral intentions of three stakeholder groups commonly in conflict. Business managers (n = 97), government environmental regulators (n = 69), and active members of pro-environmental groups (n = 49) were surveyed to assess the differences among these groups in their attitudes toward property rights, environmental regulation, and technology. We compared the influence of these attitudes and stakeholder group affiliation on intentions to engage in pro-environmental behavior. The attitudes measures explained a significant amount of the variance in behavioral intention, even after group membership was controlled. Theoretical implications of these findings for stakeholder theory are discussed along with some practical applications of these findings for stakeholder negotiations and management practices.
