Environmental Auditing

Back to: Environmental Biology 400 Level

Welcome to class!

Let’s say a company claims it’s following all the environmental rules and producing zero waste. How do we know if that’s true? That’s where environmental auditing comes in. Just like accountants check a company’s finances, environmental auditors check how well an organisation is managing its environmental responsibilities. This process ensures that companies don’t just make environmental promises—they actually keep them.

Environmental Auditing

What is Environmental Auditing?

Environmental auditing is a systematic, documented, periodic, and objective process of assessing how well a company or organisation is complying with environmental laws, regulations, and internal policies. It helps organisations identify whether their operations are safe for the environment or if they need to make improvements.

Purpose of Environmental Auditing

To verify compliance with environmental regulations and standards

To identify areas where environmental performance can be improved

To reduce risks and prevent environmental accidents or legal penalties

To demonstrate transparency and build public trust

To support sustainable practices within an organisation

Types of Environmental Audits

Compliance Audit

This audit checks whether the organisation is following environmental laws and permit conditions. For example, a cement factory in Ogun State may be assessed to ensure it does not release more dust than the law allows.

Environmental Management System (EMS) Audit

This audit examines whether the systems put in place (like ISO 14001) are effectively managing environmental aspects. For instance, is waste being properly separated, documented, and treated?

Functional Audit

Focuses on a specific environmental issue like energy use, water management, or chemical storage. A beverage company in Lagos might be audited specifically for how it manages wastewater discharge.

Stages of Environmental Auditing

Planning

Define the objectives, scope, and methods of the audit. This includes selecting the audit team and preparing a checklist.

Data Collection and Site Inspection

The auditors gather relevant documents, conduct site visits, interview staff, and take measurements.

Evaluation

The data collected is reviewed and compared with standards and expectations. Any gaps or violations are identified.

Reporting

A formal report is prepared, showing findings, conclusions, and recommended corrective actions.

Follow-Up

After the audit, the company is expected to act on the recommendations and make improvements. A follow-up visit may confirm these actions.

Benefits of Environmental Auditing

Helps reduce waste and improve resource efficiency

Avoids fines, shutdowns, or public backlash due to non-compliance

Encourages continuous improvement in environmental performance

Enhances an organisation’s reputation with regulators, investors, and the public

Nigerian Example: Dangote Cement Environmental Audits

Dangote Cement regularly undergoes environmental audits to ensure its operations do not exceed emissions standards. In some plants, the audits led to improvements in dust control and water treatment, enhancing both environmental performance and community relations.

Summary

1. Environmental auditing assesses how well an organisation follows environmental rules and manages its impacts.
2. It helps ensure legal compliance, improve operations, and protect natural resources.
3. Types include compliance audits, EMS audits, and functional audits.
4. The process includes planning, data collection, evaluation, reporting, and follow-up.
5. In Nigeria, companies like Dangote Cement use audits to improve environmental performance and avoid legal issues.
