Integrated Management System: ISO 14001, 9001 and 45001
This guide is written for business owners and managers who are considering setting up the ISO 14001 Environmental Management System together with ISO 9001 and ISO 45001 in a single integrated structure. In plain language, we explain what an integrated management system is, the steps involved in setting one up, which documents need to be prepared and the mistakes that come up most often.
What Is an Integrated Management System and Who Is It For?
An integrated management system is a management model that meets the requirements of the quality (ISO 9001), environmental (ISO 14001) and occupational health and safety (ISO 45001) standards through a single policy, a single documentation structure and shared processes. The three standards can be certified separately; integration, however, allows them to be managed not as three disconnected systems but as one system embedded in the day-to-day running of the business.
What makes this combination easier is that all three standards use ISO's common high-level structure (Annex SL). Context, leadership, planning, support, operation, performance evaluation and improvement appear in the same order in each of them. As a result, processes such as document control, internal audit, management review and corrective action can be set up once for all three.
Each standard has a different focus:
ISO 9001 focuses on meeting customer requirements and ensuring that processes run consistently.
ISO 14001 aims to identify and control the organisation's environmental aspects (such as waste, emissions, wastewater, and energy and water consumption) and to make compliance with environmental legislation systematic.
ISO 45001 is designed to prevent occupational accidents and work-related illnesses by identifying hazards and risks in the working environment in advance.
An integrated structure is particularly relevant for manufacturing facilities, hotels and tourism businesses, construction companies, logistics and warehousing firms, and businesses that process food and agricultural products. It is also important for companies that want to take part in public tenders or join the supply chains of large firms. ISO certificates are generally not a legal requirement; however, they may be requested by customers, tour operators or tender specifications.
How Is an Integrated Management System Set Up?
An integrated management system is set up through a step-by-step process that begins with an analysis of the current situation and ends with the certification audit. The order of the steps may vary slightly from one business to another; the basic flow is as follows.
1. Current situation analysis (gap analysis)
The first step is to compare what the business already does with the requirements of the standards. Existing procedures, records, permits and documents, occupational safety practices and waste management practices are reviewed, and any gaps are turned into an action list.
2. Defining the scope and context
The facilities, activities and services the system will cover are clarified. Internal and external issues affecting the business are identified, along with the expectations of interested parties such as employees, customers, neighbours, the local authority and relevant public bodies.
3. Risk, environmental aspect and hazard assessment
This step is the heart of integration. Process risks are assessed from a quality perspective, environmental aspects and impacts from an environmental perspective, and hazards and risks from an occupational health and safety perspective. Where possible, using a single method and a shared risk register keeps the system simple.
4. Listing legal and other obligations
The environmental, waste, occupational health and safety and sector-specific legislation that applies to the business is compiled into a list of obligations. This list should include the status of environmental permits and licences, waste declarations, records on UÇBS (Ulusal Çevre Bilgi Sistemi, the National Environmental Information System) and periodic measurement requirements.
5. Policy, objectives and documentation
An integrated policy is written that brings together the organisation's commitments on quality, the environment and occupational health and safety. Measurable objectives are set, and procedures, instructions and forms are gathered into a shared documentation system. The aim is not to produce a large number of documents, but to describe clearly how the work is actually done.
6. Implementation and training
The defined processes are put into practice on site. Employees receive training relevant to their roles, emergency plans are tested through drills and records are kept regularly.
7. Internal audit and management review
Once the system has been running for a while, an internal audit covering all three standards is carried out. Findings are linked to corrective actions, and top management reviews the system's performance and progress towards its objectives.
8. Certification audit
Certification is carried out by an accredited certification body, usually through a two-stage audit: first the documentation and state of readiness are assessed, then implementation on site. Periodic surveillance audits continue after the certificate is issued. Keep in mind that the consultancy firm and the certification body must be independent of each other.
Documents to Prepare and Checklist
When setting up an integrated system, both the documents required by the standards and the records showing that the business meets its legal obligations should be ready. The list below can be used as a starting point:
System scope and organisation chart
Integrated quality, environmental and occupational health and safety policy
Analysis of internal and external issues and interested parties
Risk and opportunity assessment, environmental aspect and impact assessment, hazard and risk assessment
List of legal and other obligations, with compliance evaluation records
Depending on the business, an environmental permit or licence, or the relevant exemption letter
Waste management plan, waste declaration and handover records
Measurable objectives and action plans for achieving them
Training plan, training records and competence matrix
Emergency plan and drill records
Calibration, maintenance and measurement records
Supplier and subcontractor evaluation records
Internal audit reports, nonconformity and corrective action records
Minutes of management review meetings
Common Mistakes and Points to Watch
A frequent problem with integrated systems is that the system is set up on paper but never comes to life on site. Documents prepared from ready-made templates that do not reflect the organisation's real processes cause difficulties both during audits and in day-to-day operations.
Other points to watch:
Putting three systems in a single folder is not integration. Risk assessment, internal audit and management review must genuinely be carried out jointly.
An ISO 14001 certificate does not replace legal obligations such as environmental permits or waste legislation. The certificate shows that these obligations are being tracked systematically.
The list of legal obligations should not be prepared once and then left alone; it must be updated as legislation changes. For example, the Ministry's environmental information system was recently renewed under the name UÇBS (Ulusal Çevre Bilgi Sistemi); records and declarations need to be tracked according to the current system.
Environmental aspects should not be limited to waste; energy, water, chemical use, noise and potential accident scenarios should also be assessed.
If top management does not take part in the process, objectives and resources remain unclear.
Subcontractors and suppliers should not be left outside the system; every team working on site should be aware of the rules.
Notes for Businesses in Antalya
In Antalya, an integrated management system stands out across sectors from tourism to agriculture as a way both to meet customer expectations and to keep legislative compliance in order. The region's sectoral make-up directly shapes the environmental aspects to be addressed under ISO 14001.
In hotels and tourism businesses, water and energy consumption, kitchen and organic waste, pool chemicals and wastewater management are among the main environmental aspects. Tour operators' sustainability expectations make it worthwhile to address the ISO 14001 framework together with sustainable tourism certifications.
In greenhouse farming, agricultural produce packaging and food processing facilities, packaging waste, the use of pesticides and fertilisers, and water management come to the fore. In manufacturing facilities in organised industrial zones and in construction projects, hazardous waste, dust, noise and occupational safety risks are easier to keep under control when managed from an integrated perspective.

Frequently Asked Questions
Is ISO 14001 certification mandatory?
ISO 14001 is generally not a legal requirement but a voluntary standard. However, customers, tour operators, tender specifications or the supplier requirements of large firms may ask for it. The certificate does not remove legal environmental obligations; it shows that these obligations are being tracked regularly.
Can ISO 9001, 14001 and 45001 be obtained at the same time?
Yes. Because the three standards share a common high-level structure, they can be set up together and certified through an integrated audit. This approach reduces duplicated documentation and allows processes such as internal audit and management review to be carried out in one go. A business can also start with one standard and add the others later if it prefers.
Can a small business set up an integrated management system?
Yes. The standards are written so that they can be adapted to the size of the organisation. In small businesses, the documentation structure is kept simpler and responsibilities are shared among fewer people. What matters is that the system fits the way the business actually operates.
What needs to be done after certification?
After certification, the system has to be maintained: records continue to be kept, and internal audits and management reviews continue to be carried out. The certification body checks whether the system is working through periodic surveillance audits. Changes in legislation should also be reflected in the list of obligations on a regular basis.
