Resumen
This article proposes a project to implement an Environmental Management System (EMS) suitable to a large condominiums administrator in Rio de Janeiro (Brazil), based on the parameters of the ISO 14001. The tool may be adequate to companies of any branch or size promoting competitive advantage and becoming an aggregator of value, in addition to contributing to the conservation of the environment. This is a case study developed in a condominium management company, aiming the analysis of its practices and subsequent development of EMS focused on its reality. It was evidenced through the study that there are substantial advantages in the environmental, economic and social area through the implementation of an Environmental Management System. It can also be pointed out that the real savings generated by the reduction of water and electricity consumption will have a positive impact on the coffers of the company, and these values could be applied in other real needs that until then could not be met due to lack of resources. The proposed EMS demonstrates that it is possible to apply this environmental management tool to real estate companies with a predominance of administrative processes. It is notable that mobilization for sustainability is still far below expected, confirming the gap between theory and practice. It is hoped that this work will stimulate other companies with the same size to turn to sustainable practices in their activities.
