Probably, the climate change has a critical impact on biological variation, and actually, the modernist zoos are concerned with largely with the protection of the biological variation and conserving the extinction-threatened  animals; so, there should be an obligation to reduce impacts affecting the environment, particularly, their contribution in the factors leading to climate change. Environmental management system considers a specific tool for determining, measuring, and reducing the impact of the zoo on the environment in a regular way. In order to describe the situation as well-ordered, the environmental performance level should be elevated  and there should be a research circular method consisting of four stages “plans-execution – review – Action" .added to that deep rooting the international  standard ISO 14001 system that concerns the environment's management (Turner, 2009). This research significance is crystallized in demonstrating dimensions of performance and (financial-human-technical-marketing) balance and its impact on achieving environmental demands. This research's objective is to achieve balanced performance in Giza zoo in terms of the environmental requirements compared to Dubai zoo. The data concerning the financial, human, technical, and marketing performance are collected from reports and information involved in selling-tickets rate, the training budget, and range of application of the environmental management systems in the central management in both the Giza Zoo and Dubai Zoo. The research hypotheses indicate a significant statistically correlation between indicators of the financial, technical, human and marketing performance in light of the environmental demands. The analytical analysis is used to form the theoretical framework and data is collected through examining the Giza zoo as a case study. Results indicate a statistically significant effect of the financial performance at (0,05) significance level and a statistically significant effect of the technical performance at (0.05) significance level. There is also a statistically significant effect of marketing performance at (0.05) significance level. The research recommends holding training programs for employees concerning application of the environmental management system.
