Overview
EN ISO 14019-2:2026, titled Sustainability information - Part 2: Principles and requirements for verification processes, is a European and international standard developed by CEN and ISO. This standard specifies requirements and provides guidance for the verification of declared sustainability information. It is relevant for all organizations that issue or verify sustainability information in both quantitative and qualitative formats, covering areas such as environmental, social, and governance (ESG) reporting.
Verification of sustainability information supports transparency, reliability, and comparability of disclosures, enhancing confidence among stakeholders, including investors, consumers, regulators, and business partners. The standard is applicable to various verification programmes, whether voluntarily adopted or required by regulations.
Key Topics
-
Scope of Verification
EN ISO 14019-2:2026 outlines principles for verifying declared sustainability information, regardless of the underlying regulatory or voluntary reporting requirements. It addresses both quantitative data (e.g., emissions figures, resource consumption) and qualitative statements (e.g., policy commitments, narrative reports).
-
Verification Process
The standard structures the verification process into defined phases, including:
- Pre-engagement: Confirming objectives, deliverables, scope, and necessary criteria
- Engagement and Planning: Agreements between parties, assembling the verification team, and risk/materiality assessment
- Evidence Gathering: Applying appropriate techniques to authenticate both quantitative and qualitative information
- Execution & Review: Communicating findings, addressing insufficiencies, and reviewing evidence
- Decision & Assurance: Issuing an assurance statement or report, with clear guidance for different levels and types of opinions (unmodified, qualified, adverse, disclaimed)
-
Materiality and Relevance
The standard emphasizes the importance of materiality assessment and relevance determination during verification, ensuring that information verified is significant and aligned with the intended users’ needs.
-
Assurance Levels
Provides frameworks for determining and stating the level of assurance-crucial for distinguishing between reasonable, limited, or no assurance engagements.
-
Continuous Improvement
Annexes offer further guidance on sampling, assurance levels, inherent risk, uncertainty, and verification approaches for qualitative information.
Applications
EN ISO 14019-2:2026 delivers practical value for diverse stakeholders and use cases:
- Organizations and Companies: Ensures that declared sustainability and ESG information is credible, verifiable, and aligned with standards, improving accountability and supporting compliance with legislation or supply chain requirements.
- Verification Bodies: Outlines robust, repeatable processes for verifying sustainability information, helping to standardize verification services and ensure consistency across engagements.
- Regulators and Policy Makers: Supports regulatory frameworks that require verified sustainability information, facilitating reliable compliance and reporting.
- Investors and Stakeholders: Enhances confidence in sustainability, ESG, and non-financial information used for investment, procurement, or partnership decisions.
- SMEs: Enables small and medium-sized enterprises to validate their sustainability efforts for voluntary reporting, supply chain participation, or internal improvement.
Related Standards
For comprehensive conformity assessment and sustainability reporting, EN ISO 14019-2:2026 should be considered alongside related standards:
- ISO 14019-1: General principles and requirements for validation and verification
- ISO/IEC 17029:2019: Conformity assessment - General principles and requirements for validation and verification bodies
- Other parts of the ISO 14019 series: Covering terminology, validation processes (ISO 14019-3), and requirements for bodies and personnel (ISO 14019-4)
Practical Value
Implementing EN ISO 14019-2:2026 helps organizations build trust in their sustainability claims and meet growing demands from markets and regulators for transparent, independently verified information. With a standardized verification process, it advances the credibility and comparability of sustainability disclosures across industries and regions, empowering better decision-making and supporting global sustainability objectives.
