Environment refers to the external existence of the organization's operation activities, including air, water, land, natural resources, plants, animals, people, and their interrelationships.

The environmental management system is a part of the management system within an organization, which is used to manage environmental factors (the elements of an organization’s activities, products and services that interact with the environment or can interact with the environment), fulfill compliance obligations, and respond to risks and opportunity.

The environmental management system provides a framework for organizations to protect the environment, respond to changing environmental conditions, while maintaining a balance with social and economic needs; stipulates the requirements of the environmental management system so that the organization can achieve the expected results of the environmental management system set by it.

The successful implementation of an environmental management system depends on:

• Commitments at all levels and functions of the organization under the leadership of top management.

• Organizations can take advantage of opportunities to prevent or mitigate adverse environmental impacts and enhance beneficial environmental impacts.

• By incorporating environmental management into the organization's overall management system, the top management can effectively respond to its risks and opportunities.

• The detail and complexity of the environmental management system will depend on the environment in which the organization is located, the scope of its environmental management system, its compliance obligations, and the nature of its activities, products and services, including its environmental factors and related environmental impacts .
