ISO 14030-3:2022

Overview

ISO 14030-3:2022 - "Environmental performance evaluation - Green debt instruments - Part 3: Taxonomy" defines a comprehensive taxonomy for eligible investment categories that can be financed or refinanced through green debt instruments (e.g., green bonds and green loans). The standard categorizes economic sectors, explains eligibility criteria for projects, assets and supporting expenditures, and provides guidance on climate change adaptation and examples of thresholds and exclusions. It is part of the ISO 14030 series and is intended to support transparent, consistent classification of green finance.

Key topics and technical requirements

• Taxonomy of eligible activities: Sector- and sub-sector-level classification (e.g., agriculture, forestry & fishing; manufacturing; renewable energy & energy efficiency; water & waste; transport; ICT; construction).
• Eligibility criteria: Describes rationale for inclusion, environmental benefits and environmental performance indicators required to demonstrate contribution.
• Do No Significant Harm (DNSH): Activities must contribute to environmental objectives while avoiding significant harm to other environmental goals (DNSH considerations are included for each taxonomy entry).
• Life-cycle perspective: Environmental assessments are taken at project/asset level with upstream and downstream impacts considered.
• Adaptation guidance: Annex A provides sector-specific guidance for climate adaptation.
• Thresholds and exclusions: Annex B supplies examples of thresholds and exclusions that users can adopt or adapt; Annex C gives guidance on recognising other suitable taxonomies.
• Alignment with process standards: Designed to be used with ISO 14030-1 and ISO 14030-2 for green bond and loan processes.

Applications and who uses it

ISO 14030-3 is practical for organizations and stakeholders involved in green finance and ESG assessment:

• Issuers and originators preparing green bond/loan frameworks and seeking to define eligible use-of-proceeds.
• Lenders, investors and asset managers performing due diligence and classifying green investments.
• Sustainability/ESG teams building internal taxonomies or reporting on environmental performance indicators.
• Rating agencies and verification bodies assessing conformity of debt instruments with green taxonomy criteria.
• Regulators and policymakers referencing a recognized international taxonomy when designing green finance guidance.

Practical uses include selecting eligible project lists, setting reporting and monitoring KPIs, applying DNSH screening, adopting thresholds/exclusions, and demonstrating alignment with international green finance good practice.
