Which clause of ISO 14001 requires the organization to document and communicate an environmental policy?

The requirement to document and communicate an environmental policy is found in Clause 5.2 of ISO 14001. This clause specifically outlines that an organization must establish, implement, and maintain an environmental policy that is appropriate to its purpose and context, and that it must ensure the policy is communicated within the organization as well as made available to relevant interested parties.

Clause 5.2 emphasizes the importance of leadership and commitment in environmental management systems. The environmental policy serves as a framework for the organization to set its environmental objectives and provides guidance for the organization's actions and decision-making related to environmental issues. Moreover, the communication of this policy helps ensure that all employees and stakeholders are aware of the organization's environmental commitments and their roles in achieving these commitments.

In contrast, the other clauses mentioned focus on different aspects of the environmental management system, such as understanding the organization's context, planning for environmental aspects, and operational planning and control, rather than the specific requirement for an environmental policy.
