Environmental management systems and standards
This domain tests whether you can read an environmental management system (EMS) as an integrated system, not as a document set. The central model is ISO 14001:2015, structured as context (Clause 4), leadership (5), planning (6), support (7), operation (8), performance evaluation (9), and improvement (10). ISO 14004 provides guidance, ISO 14031 addresses environmental performance evaluation, ISO 14040 covers life-cycle assessment, and ISO 14064 addresses greenhouse-gas quantification and verification.
Core rules and concepts
- Aspects and impacts: an environmental aspect is an activity, product, or service that interacts with the environment; an impact is the resulting change. Significance criteria usually combine severity, likelihood, legal limits, and controls.
- Compliance obligations: identify legal and other requirements, then determine how they apply. A permit is evidence of an obligation, not the whole obligation.
- Planning: address risks and opportunities, set objectives, establish operational controls, and prepare for emergencies.
- Performance evaluation: monitor and measure, evaluate compliance, conduct internal audits, hold management reviews, and manage nonconformity and corrective action.
Worked example
A metal-finishing plant discharges treated wastewater. The aspect is “discharge of treated wastewater”; the impact is a pH shock to the receiving stream. The permit sets pH 6–9, and monitoring records show pH 5.5. The significance rating is high because the legal limit is exceeded and aquatic harm is plausible. The audit trail should link the aspect register, permit condition, monitoring record, calibration record, and corrective action. The correction may be immediate neutralization; the corrective action must address root cause, such as failed dosing control or inadequate alarm response.
Traps that cost marks
Confusing aspect with impact; treating the legal register as complete merely because it exists; assuming a significant aspect is controlled only because a procedure exists; and confusing management review with internal audit. Also watch for document control failures presented as environmental nonconformities when they are actually system weaknesses.
