Some studies have shown that consumers often prefer to choose environmentally friendly raw products (Weber, 1990). When investigating the market demand for Taiwan enterprises, environmental management was identified as a powerful force (Wen & Chang, 1998). Public pressure has been found to play an important role in CEM (Gunningham, Kagan & Thornton, 2003). It was found that when developing an environmental plan, pressure from the public in CEM is generated by a number of decision-making policies in large companies in Canada (Henriques & Sadorsky, 1996)
