Pros and Cons for Internal and External ISO 14001 Audits

Environmental sustainability has become a paramount concern for organizations worldwide. As a result, many companies seek to implement robust environmental management systems to minimize their ecological footprint. ISO 14001 Certification is a recognized benchmark for these efforts. Whether conducted internally or externally, ISO 14001 audits play a vital role in the certification process. In this blog, we will explore the advantages and disadvantages of both internal and external ISO 14001 Audits, shedding light on the factors organizations should consider as they work towards ISO 14001 certification.

ISO 14001 Audits: An Essential Component of Certification  

It’s important to comprehend the function of ISO 14001 audits in the certification process before delving into the benefits and drawbacks. A globally accepted standard for environmental management systems (EMS) is ISO 14001. An organisation’s commitment to environmental responsibility is shown by ISO 14001 certification, which provides the foundation for establishing and improving an organisation’s environmental performance. 

Internal ISO 14001 Audits: Pros and Cons  

Here we delve into pros and cons of Internal ISO 14001 Audits:


  1. Since internal audits do not need external auditing costs, they are usually more economical. These audits may be carried out by organisations using their internal resources.  
  2. The EMS may be continuously monitored and improved by conducting internal audits regularly. This facilitates the quick identification and resolution of problems. 
  3. Because they are more familiar with the operations and culture of the company than external auditors are, internal auditors are better able to spot areas that need improvement. 
  4. Internal audits have the potential to cultivate an organisational culture of environmental stewardship by increasing employee involvement in the auditing process.  


  1. To keep peace inside the company, internal auditors might be less objective and more prone to ignore problems or non-conformities. 
  2. There could be gaps in the audit process if internal auditors lack the same training and experience as external auditors. 
  3. Conflicts of interest might arise for internal auditors if their conclusions result in unfavourable consequences like budget cutbacks or job losses.  
  4. Pros and Cons of External ISO 14001 Audits  


  1. Since they are outside the company and have no stake in the audit’s outcome, external auditors provide a more unbiased evaluation. 
  2. Because of their specialised training and expertise, external auditors guarantee a thorough assessment of the EMS. 
  3. The ISO 14001 certification obtained using external audits is often more extensively acknowledged and esteemed, augmenting the organisation’s standing.  
  4. Because their credibility and reputation are on the line, external auditors are less inclined to ignore problems or non-conformities. 


  1. Due to auditor fees, travel expenses, and other related expenditures, external audits are more expensive. This may be a major disadvantage, particularly for small businesses. 
  2. External audits are usually carried out every year or every two years, restricting the frequency of ongoing observation and development. 
  3. Limited Understanding: It’s possible that external auditors won’t fully understand the distinctive culture and processes of the company, which might result in fewer useful suggestions. 

Choosing the Right Approach for ISO 14001 Certification 

The choice of whether to do ISO 14001 audits internally or externally is mostly based on the unique requirements, assets, and conditions of an organisation. To optimise the advantages and minimise the disadvantages, some organisations can decide to combine the two strategies. When making this choice, keep the following important things in mind: 

  1. Analyse your staff availability and budgetary resources. Larger organisations may choose external audits, while smaller ones with less finances could find internal audits more practical. 
  2. Think about the degree of experience that exists inside your company. Using your knowledgeable internal auditors’ expertise might be an affordable solution to keep ISO 14001 standards compliant. 
  3. Determine if an unbiased, objective review is necessary. External audits could be a better choice if you are worried about bias or inexperience in your internal audit team. 
  4. Make sure you are aware of the industry certification criteria and if external audits are required for industry recognition or compliance.  
  5. Take into account the values and culture of your company. Internal audits are more attractive in organisations that place a high priority on employee participation and cultural integration. 


Organisations seeking to get certified as environmentally sustainable must conduct ISO 14001 audits. The organisation’s resources, experience, and unique requirements should be carefully considered before deciding between internal and external audits. Whichever strategy is chosen, the ultimate objective should be to constantly improve environmental performance and the EMS while adhering to the requirements of ISO 14001 certification. Ultimately, the choice should demonstrate an organisation’s dedication to sustainability and environmental responsibility.
