How to Perform & Report EMS Audits with EMS Audit Software

An environmental management system (EMS) audit evaluates how well your organization manages its environmental responsibilities. When organizations align their EMS with ISO 14001, they can achieve 20% to 30% improvements in environmental performance, demonstrating twice the environmental and occupational health and safety performance compared to non-adopters. They also experience notable gains in operational efficiency, energy use optimization, waste management, and the effectiveness of incident response procedures. Globally, EMS adoption varies by region. The Asia-Pacific region leads adoption, with China and Japan accounting for nearly 60% of all ISO 14001 certificates. In Europe, countries like Italy, the UK, Spain, and Germany show strong and steady growth in certifications. In contrast, the United States trails behind in EMS adoption. Regular EMS audits are essential to enhance environmental performance, which leads to achieving and maintaining certification.

In this blog, we have discussed EMS audits in detail, covering the steps to perform them, types of environmental audits, and how EMS audit software can simplify auditing and reporting. 

What is an Environmental Management System Audit?

An environmental management system (EMS) audit is a systematic, independent, and documented process to objectively evaluate whether your EMS complies with specified audit criteria, including ISO 14001 or other relevant standards. It determines if the EMS is effectively implemented and maintained, and whether it meets your organization’s environmental policy and objectives. The audit examines processes, procedures, records, and practices that influence environmental performance. It identifies non-conformities, risks, and areas for improvement.

EMS audits are essential for:

• Organizations seeking ISO 14001 certification or maintaining compliance
• Industries with significant environmental impacts (e.g., manufacturing, construction, energy, chemicals)
• Companies facing regulatory or stakeholder scrutiny
• Organizations with internal sustainability or ESG goals

Auditors can be internal or external (third-party auditors or certification bodies).

EMS audits must be performed:

• Regularly, as part of the EMS internal audit schedule (typically annually or semi-annually)
• Before certification or recertification audits
• After major changes in operations, processes, or legal requirements
• Following environmental incidents or non-compliance events
• During supplier evaluations, if environmental performance forms part of the procurement criteria

Why is EMS Audit Important?

Here’s why EMS audits are essential:

• An EMS audit helps you identify gaps in meeting environmental laws and regulations. It ensures that your processes, permits, and documentation align with legal requirements, minimizing the risk of non-compliance penalties and operational shutdowns.
• They assess how well your organization manages environmental aspects such as energy use, waste, emissions, and resource consumption. They enable you to reduce environmental impact, align with sustainability goals, and continuously improve your performance.
• Environmental risks can disrupt operations and damage brand reputation. EMS audits identify vulnerabilities and recommend preventive measures, helping you mitigate potential environmental liabilities before they escalate.
• Through the identification of wasteful practices and energy inefficiencies, EMS audits reveal opportunities to optimize resource use. This results in cost savings, particularly in energy, water, and waste management, without compromising compliance or quality.
• A well-executed EMS audit demonstrates transparency and accountability. It reinforces your commitment to environmental management, earning the trust of customers, regulators, investors, and the public.
• EMS audits are integral to achieving and maintaining ISO 14001 certification. They verify whether your system meets the standard’s requirements and support the implementation of best practices, ensuring readiness for external certification bodies.
• They create opportunities for employees to understand their environmental responsibilities. Engaging staff in audit processes increases awareness and drives organization-wide participation in sustainability efforts.

What are the Three Types of Environmental Audits?

Environmental audits can be classified into three distinct categories based on their scope and objectives:

1. Environmental Compliance Audit

It evaluates your organization’s adherence to environmental laws, regulations, permits, and internal standards. The focus lies on detecting non-compliance issues and implementing corrective actions to mitigate legal and financial risks.

Types of environmental compliance audits include:

• Internal EMS Audits: Conducted by in-house teams, they assess how effectively your EMS meets internal policies and regulatory requirements.
• External or Third-Party Audits: Performed by independent experts, these provide an unbiased evaluation of your compliance status. They are particularly valuable when preparing for regulatory inspections or seeking assurance for stakeholders.
• Certification Audits: These determine whether your EMS meets the standards of frameworks like ISO 14001. Leading to certification and enhancing credibility and stakeholder trust.

2. Environmental Management Audit

It reviews how well your environmental policies, procedures, and objectives are being implemented and maintained. Unlike compliance audits, the focus is broader. An environmental management audit evaluates overall environmental strategy, performance metrics, and the effectiveness of environmental programs. 

Both internal and external audits fall under this category. Internal audits help you identify performance gaps and align operations with environmental goals. External audits provide an objective review and often deliver strategic insights for continuous improvement.

3. Functional Environmental Audit

Functional audits target specific operations, departments, or processes within your organization. These are detailed, focused assessments designed to uncover inefficiencies, risks, or impacts related to a particular function, such as waste management, energy use, or hazardous material handling.

Again, these can be both internal and external. Internal functional audits are conducted by specialized teams familiar with your systems. External functional audits are carried out by domain experts who bring industry benchmarks and technical objectivity.

What is the EMS Audit Process?

The EMS audit process follows a defined sequence of steps, listed below, to examine whether the EMS is effective, compliant, and aligned with environmental objectives.

Create an EMS Audit Plan

Begin by defining the audit scope, objectives, and criteria. Select qualified auditors and schedule audit dates. Prioritize areas with high environmental impact or past non-conformities. Planning also involves a risk-based approach to ensure critical areas receive adequate focus. A detailed audit plan is then shared with all stakeholders to align expectations.

Review Documents

Assess EMS documentation before the on-site audit. Review the environmental policy, legal registers, objectives, procedures, training records, and internal audits. Evaluate whether these documents align with ISO 14001 requirements. It ensures the system is properly designed and implemented on paper before checking its application.

Perform On-Site Audits

Conduct on-site verification through interviews, observation, and inspection, validating practical implementation. Confirm that EMS procedures are followed at all operational levels. Collect objective evidence to support audit findings. Evaluate employee awareness, operational control, emergency preparedness, and legal compliance.

Identify Non-Conformities 

Identify deviations from EMS requirements, whether internal procedures or ISO 14001 standards. Classify non-conformities as major or minor. Provide clear, factual evidence and link each issue to specific clauses. This ensures traceability and transparency, helping the organization understand exactly what needs correction.

During EMS audits, identified nonconformities are generally categorized as either major or minor, based on their impact on the EMS’s effectiveness. Common nonconformities identified during EMS audits include:

• Failure to document environmental procedures
• Missing or inadequate records
• Inaccurate or missing equipment calibration
• Ineffective evaluation of compliance
• Lack of management reviews or incomplete reviews
• Lack of a compliance register or a register not maintained
• Insufficient training or training records
• Environmental aspects and impacts are not fully recorded or evaluated
• Non-implementation of corrective or preventive actions
• Inconsistent practices and procedures 
• Ineffective EMS audit program

Document Audit Findings and Report Them

Compile findings into a structured audit report. Include audit scope, objectives, methodology, observations, non-conformities, and positive practices. Ensure the report is objective, concise, and actionable. Submit the report to management for review and formal response. Proper documentation forms the basis for effective corrective action.

The key components of EMS audit reports include:

• Audit scope, objectives, criteria, and process description
• Methodology and evidence collected
• Findings summary, detailing satisfactory findings, non-conformance findings, and opportunities for improvement
• Nonconformance and corrective actions
• Conclusions and recommendations
• Executive summary
• Report distribution and follow-up plan

Implement Corrective Actions

For each non-conformance, the organization must determine root causes and implement corrective actions. Define responsibilities, deadlines, and methods for verification. Ensure actions address the underlying issues rather than symptoms. Effective corrective actions prevent recurrence and strengthen the EMS.

Follow-Up and Monitor

Conduct follow-up audits or reviews to verify that corrective actions were implemented and are effective. Monitor key environmental indicators to assess sustained compliance and performance. Continual monitoring ensures the EMS remains dynamic and responsive to changes in operations, regulations, and environmental impacts.
