Overview
ISO 14015:2022 - Environmental management - Guidelines for environmental due diligence assessment - provides structured guidance for conducting an environmental due diligence (EDD) assessment. The standard describes a systematic, evidence-based process to identify environmental aspects, issues and conditions and, where appropriate, determine their business consequences (liabilities, regulatory risks, remediation needs, and impacts on transactions). ISO 14015 is intended for use during operations, acquisitions, divestitures, and as part of broader due diligence and ESG evaluations. It explicitly does not cover environmental audits, environmental impact assessments, performance/efficiency assessments, or intrusive site investigations and remediation.
Key topics and technical requirements
- Principles of assessment: evidence-based, risk-based, fair presentation and confidentiality.
- Roles and responsibilities: clear definition of the client, assessor, assessment provider and representative of the assessee.
- EDD process stages: planning; information gathering; verification and validation; evaluation; and reporting.
- Planning elements: setting terms and objectives, defining scope and assessment criteria, feasibility, and preparing an assessment plan.
- Information methods: review of documentation, observation of physical conditions, interviews, and verification/validation approaches.
- Evaluation: identifying environmental issues and determining potential business consequences (historic contamination, current compliance risks, climate-related risks, supply-chain exposures).
- Reporting: recommended report content and distribution to stakeholders.
- Assessor competence: integrity, ethical conduct, competence determination and ongoing evaluation.
- Annexes and guidance: examples of assessment topics and sources, observation checklists, interviewees and a sample EDD report table of contents.
Practical applications
- Pre-acquisition or divestiture due diligence for corporate transactions and asset transfers.
- Internal/self-assessments to understand environmental liabilities and compliance risks.
- Support for investors, lenders and insurers assessing environmental risk in financial decisions.
- Informing ESG reporting, risk management and remediation planning without replacing intrusive site investigations.
- Use by regulatory bodies and transaction service providers to harmonize environmental risk evaluation.
- Corporate buyers and sellers, asset owners and operators
- Financial institutions, investors and insurance underwriters
- Environmental consultants, assessors and transaction advisors
- Regulatory and enforcement bodies and internal audit teams
- Small and medium-sized enterprises seeking consistent environmental risk appraisal
Related standards
ISO 14015 complements other environmental management guidance and can be used alongside standards and guidance for environmental management systems and auditing (for example, ISO 14001 and ISO 19011), and with relevant national or local regulatory frameworks.
