ISO 14001:2026 gap analysis: what to review first 

What is a gap analysis? 

A gap analysis is a structured comparison between your current EMS and the requirements of ISO 14001:2026. 

It doesn’t have to be complex. Put simply, it’s a process you design to look at where your existing system might fall short of the updated standard. As part of the process, you’ll need to:  

• Review your current EMS processes and documentation 

• Compare them against the new requirements 

• Identify gaps, weaknesses, or areas that need improvement 

• Define the actions you’ll take to close those gaps 

 The output of your gap analysis is usually a working table that should show the requirement (under ISO 14001:2026), your current approach, the gap, and the action you’ll take to close it.   

What to review first in your ISO 14001:2026 gap analysis 

Eventually, you’ll need to review every clause in appropriate detail. However, start by focusing on the areas where ISO 14001:2026 is expected to introduce the most significant changes.  

Environmental context 

Start by reviewing how your organisation defines its environmental context. This area has been expanded and clarified in ISO 14001:2026, with a stronger expectation that organisations consider their wider environmental conditions and long-term impacts.  

• Have you explicitly considered climate change risks and impacts, e.g. physical risks, transition risks and regulatory pressures? 

• Have you expanded your context to include broader environmental systems, such as biodiversity, ecosystems and natural resource constraints? 

• Are environmental conditions now assessed in a more forward-looking way, rather than just current-state impacts? 

• Have you updated your interested parties to reflect increasing environmental expectations, such as regulators, investors and supply chain pressures related to sustainability? 

 These aren’t brand new concepts. You’ll be familiar with them, at least in general. However, the 2026 revision makes them more explicit, broader in scope, and harder to pass off as high-level, irrelevant statements. This is where we expect some of the most significant and immediate gaps to appear.  

Risks and opportunities 

Next, review your approach to risk-based thinking. While risk and opportunity planning already exists in ISO 14001:2015, we expect clearer structure, stronger requirements and greater emphasis on how your assessments link to relevant actions in the 2026 revision. Your organisation likely already identifies environmental risks. If you do have gaps, we expect them to usually relate to depth, consistency and integration with your EMS. Look at:  

• Are risks and opportunities defined using a consistent and structured methodology, rather than informal or high-level lists? 

• Is there a clear link between identified risks and your EMS planning, including objectives, controls and operational processes? 

• Have you expanded risk consideration to include emerging environmental pressures, such as climate transition risks or regulatory changes? 

• Can you demonstrate traceability from risk identification through to action and monitoring?  

Lifecycle perspective 

Once again, lifecycle thinking is still present under ISO 14001:2026, just as it was in the previous iteration. However, you’ll now be expected to demonstrate how you apply this in practice, rather than potentially treating it as a high-level concept. Auditors will expect to see evidence that your organisation actively uses lifecycle thinking, rather than just considering it. Questions to ask include:   

• Are your lifecycle impacts assessed in a more detailed and practical way? 

• Have you extended lifecycle consideration into your design, procurement and end-of-life stages where relevant? 

• Are your environmental controls influenced by lifecycle thinking? 

• Can you demonstrate how life-cycle considerations affect your decisions, such as material selection, supplier choice or service delivery?  

Suppliers and external providers 

One of the areas likely to require closer review under ISO 14001:2026 is your EMS’s control measures for external providers. This reflects a growing pressure on companies to manage environmental impacts across their supply chains. Here, you’ll need to ask yourself:  

• Do you evaluate suppliers based on defined environmental performance criteria, not just cost or quality? 

• Have you formalised how your environmental requirements are communicated to suppliers and contractors? 

• Do you monitor or review your suppliers based on their environmental performance, rather than approved once and left unmanaged? 

• Do you consider supply chain environmental risks, such as high-impact materials or non-compliant providers?  

A basic ‘approved supplier’ list is unlikely to meet the updated expectations. From now on, you’ll need more structure and ongoing oversight, as well as stricter controls.  

Planning for change 

Under the 2026 revision, ISO 14001-compliant businesses will likely need to introduce clearer expectations around managing change, both within your organisation and its environmental context. Some of the things to consider here include:   

• Do you have a defined process for assessing environmental risks before implementing changes, such as new processes, equipment or sites? 

• Is environmental impact considered as part of business change planning, rather than reviewed after the fact? 

• Are changes to external conditions (e.g. regulations, climate risks, stakeholder expectations) actively monitored and integrated into your EMS? 

• Can you demonstrate that changes trigger updates to risks, controls and objectives where necessary?  

In short, this change in requirements is a shift towards proactive environmental management. This helps to ensure your EMS remains effective as conditions change over time.  

How to approach your gap analysis 

1. Review the ISO 14001:2026 changes – at first, focus on the updated themes rather than every clause. 

1. Assess your current EMS – use existing documentation, procedures and records. 

1. Identify and record gaps – keep this clear and practical, and avoid overcomplicating anything. 

1. Prioritise actions – focus on high-risk or high-impact areas first. 

1. Create an action plan – assign responsibilities and realistic timelines. 

What should your ISO 14001:2026 action plan include? 

Once you’ve identified your gaps, the next step is to turn them into a practical action plan. We won’t go into this in detail here, but it’s an important next step after your gap analysis. 

Your gap analysis should already include an ‘Action’ column. For smaller or simpler EMS updates, this may be enough, especially if your actions are limited in number and easy to manage. In this case, you may not need a separate action plan. 

However, for most organisations, it’s good practice to develop a separate action plan. This allows you to manage responsibilities, priorities and progress more effectively, particularly where multiple teams or more complex changes are involved. You may even be able to set up a system where updates to your gap analysis will automatically appear in the action plan, and vice versa. 

Much like your gap analysis, your action plan doesn’t need to be complex. Typically, it should clearly show:  

• The gap identified 

• The action required to close it 

• The person responsible 

• The priority level 

• The target completion date 

• The resources, training, or support needed 

• How completion will be checked or evidenced  

Auditors don’t require a specific format, but they will expect you to clearly identify gaps, assign actions and track progress. They’ll also expect you to show that you’ve reviewed any completed actions and confirmed they’re effective.  

Need help with your ISO 14001:2026 transition? 

A gap analysis may sound technical, but you can approach it step by step. It’s vital for preparing for ISO 14001:2026. The sooner you can start your gap analysis, the better. 

Done properly, a good gap analysis gives you a clear understanding of what needs updating, a structured transition plan, and confidence going into your next audit. It also helps you strengthen your EMS for better performance. In other words, it’s not just a compliance exercise. 

The most effective way to prepare for your ISO 14001:2026 transition is to work with trusted ISO consultants like ISO QSL. At ISO QSL, our team of experts supports organisations like yours with EMS updates and implementation. We provide expert support, staff training, and internal auditing to ensure you’re fully prepared for your transition audit.
