ISO 14001 sets out the criteria for an environmental management standard or (EMS).
Because ISO 45001 is designed to integrate with other ISO management systems standards, ensuring a high level of compatibility with the new versions of ISO 9001 (quality management) and ISO 14001 (environmental management), businesses that already implement an ISO standard will have a leg up if they decide to work toward ISO 45001.
The ISO 9001 standard is designed to help organizations ensure that they meet the needs of customers and other stakeholders while meeting statutory and regulatory requirements.
