True or False: ISO 14001 refers to a series of voluntary standards in the environmental field.

ISO 14001 indeed refers to a series of voluntary standards that provide a framework for organizations to follow in order to effectively manage their environmental responsibilities. The standard is part of the ISO 14000 family, which focuses on various aspects of environmental management. An organization that implements ISO 14001 can improve its environmental performance, comply with applicable laws and regulations, and engage with stakeholders more effectively regarding its environmental impact.

The reference to these standards as "voluntary" emphasizes that organizations are not legally required to adopt them; rather, they choose to do so to enhance their operational practices and demonstrate a commitment to sustainability. This makes ISO 14001 applicable to a wide range of organizations, regardless of their size or location, as they can benefit from adopting sustainable practices.

In contrast, the other options would suggest limitations or specifications that do not align with the general understanding of ISO 14001's broad applicability and voluntary nature.
