EU Taxonomy
The EU Taxonomy is a classification system that defines which economic activities are environmentally sustainable, guiding investment, reporting, and capital allocation.
Investors, lenders, and funds increasingly use the EU Taxonomy to screen investments, allocate capital, and define sustainable portfolios.
Defines what qualifies as environmentally sustainable activity
Used in CSRD reporting and sustainable finance
Impacts investment decisions and capital flows

The Six Environmental Objectives
An activity must contribute to at least one of six objectives to be considered taxonomy-aligned.
Climate change mitigation
Climate change adaptation
Water and marine resources
Circular economy
Pollution prevention
Biodiversity and ecosystems
These objectives define the scope of environmental sustainability
Detailed Environmental Objectives
Each environmental objective has specific criteria and requirements for substantial contribution. Climate change mitigation and adaptation have the most developed technical screening criteria, with other objectives progressively implemented.
1. Climate Change Mitigation
Activities that substantially contribute to stabilizing greenhouse gas concentrations in the atmosphere:

Climate Objectives Have Priority
Climate change mitigation and adaptation objectives have the most developed technical screening criteria and are the primary focus for initial taxonomy implementation. Other objectives are being progressively developed with sector-specific criteria.
Core Criteria (How It Works)
To be taxonomy-aligned, an activity must meet four criteria simultaneously.
Substantially Contribute - To at least one environmental objective
Do No Significant Harm (DNSH) - Not harm other objectives
Meet Minimum Safeguards - Social and governance standards
Meet Technical Screening Criteria - Quantitative thresholds
All four criteria must be met simultaneously
Failing any one of the criteria means the activity is not considered taxonomy-aligned
Technical Screening Criteria
Technical screening criteria (TSC) are the quantitative and qualitative thresholds that determine whether an activity substantially contributes to an environmental objective. TSC are defined at the activity level and vary by sector and objective.
Activity-Level Criteria
TSC are defined for specific economic activities (NACE codes). Each activity has specific criteria depending on which environmental objective it contributes to. For example, renewable energy generation has specific capacity and efficiency thresholds, while building renovation has specific energy performance requirements.
Substantial Contribution Criteria
Activities can substantially contribute through three pathways:
- • Transition activities: Activities that enable the transition to a sustainable economy (e.g., manufacturing low-carbon technologies)
- • Enabling activities: Activities that directly enable other sustainable activities (e.g., manufacturing renewable energy equipment)
- • Green activities: Activities that are already environmentally sustainable (e.g., renewable energy generation)
Quantitative Thresholds
TSC include specific quantitative thresholds such as:
- • Emission thresholds: Maximum GHG emissions per unit of output (e.g., gCO2e/kWh for electricity)
- • Efficiency thresholds: Minimum energy efficiency or resource efficiency standards
- • Recycling thresholds: Minimum recycled content or recovery rates
- • Performance thresholds: Minimum environmental performance indicators
Sector-Specific Delegated Acts
TSC are published through delegated acts for specific sectors. Climate-related delegated acts (mitigation and adaptation) cover activities in sectors such as energy, manufacturing, transport, buildings, agriculture, and forestry. Delegated acts for other environmental objectives are being progressively developed.
TSC Are Activity-Specific
Technical screening criteria are defined at the activity level, not the company level. A company may have multiple activities, some aligned and some not, depending on whether each activity meets its specific TSC.
DNSH & Minimum Safeguards
Beyond substantial contribution, taxonomy-aligned activities must satisfy Do No Significant Harm (DNSH) requirements and minimum safeguards for social and governance standards.
Do No Significant Harm (DNSH)
An activity that substantially contributes to one environmental objective must not significantly harm any of the other five objectives:
- • Climate mitigation activities must not harm climate adaptation, water, circular economy, pollution, or biodiversity
- • Renewable energy projects must not cause significant harm to biodiversity (e.g., avoid protected areas)
- • Industrial processes must not cause significant water pollution or resource depletion
- • DNSH assessment requires evaluation of potential impacts on all other objectives
DNSH Evidence Requirements
Companies must provide evidence that activities meet DNSH requirements:
- • Screening: Identify potential significant harm to other objectives
- • Assessment: Evaluate the significance of potential impacts
- • Mitigation: Implement measures to avoid or reduce significant harm
- • Documentation: Maintain evidence of DNSH compliance for each activity
Minimum Safeguards
Taxonomy-aligned activities must meet minimum safeguards based on international standards:
- • Human rights: UN Guiding Principles on Business and Human Rights
- • Labor standards: ILO core labor standards (freedom of association, collective bargaining, child labor, forced labor)
- • Corruption: OECD Guidelines for Multinational Enterprises, UN Convention against Corruption
- • Tax good governance: OECD BEPS minimum standards
- • Fair competition: EU competition law
Compliance Evidence
Companies must have policies and procedures in place to ensure compliance with minimum safeguards. This includes due diligence processes, grievance mechanisms, and regular monitoring. Evidence of compliance must be documented and available for disclosure under CSRD.
DNSH and Minimum Safeguards Are Non-Negotiable
Even if an activity substantially contributes to an environmental objective, it cannot be taxonomy-aligned if it causes significant harm to other objectives or fails to meet minimum safeguards. These are absolute requirements.
Disclosure Requirements
Under CSRD, companies must disclose taxonomy alignment metrics that link sustainability performance directly to financial statements. Disclosures are required for the six environmental objectives, with climate objectives having mandatory disclosure from the outset.
Key Disclosure Metrics
Companies must disclose three primary metrics for each environmental objective:
- • Taxonomy-aligned turnover: Percentage of revenue from taxonomy-aligned activities
- • Taxonomy-aligned capex: Percentage of capital expenditure on taxonomy-aligned activities
- • Taxonomy-aligned opex: Percentage of operating expenditure on taxonomy-aligned activities
Eligible vs Aligned Turnover
Companies must disclose both eligible and aligned turnover:
- • Eligible turnover: Revenue from activities covered by the taxonomy framework
- • Aligned turnover: Revenue from activities that meet all four taxonomy criteria
- • Alignment ratio: Aligned turnover as a percentage of eligible turnover
Phase-In of Objectives
Disclosure requirements are phased by environmental objective:
- • Climate objectives (mitigation & adaptation): Mandatory from first reporting year
- • Water, circular economy, pollution, biodiversity: Mandatory from 2024 for large companies, 2026 for SMEs
- • Non-EU companies: Phased based on CSRD wave implementation
Financial Institution Disclosures
Financial institutions (banks, asset managers, insurers) have additional disclosure requirements. They must disclose the taxonomy alignment of their assets, investments, and lending portfolios. This includes green asset ratios (GAR) for banks and taxonomy alignment of investment portfolios for asset managers.
Disclosures Link ESG to Financials
Taxonomy disclosures directly link sustainability performance to financial metrics (revenue, capex, opex). This enables investors to assess the sustainability of a company's business model and capital allocation decisions.
Eligibility vs Alignment (Important)
Understanding the distinction between eligibility and alignment is critical for taxonomy compliance.
Eligibility
Activity is covered by the taxonomy
Framework includes the activity
Alignment
Activity meets all criteria
Substantial contribution + DNSH + safeguards + technical criteria
Not all eligible activities are aligned
Alignment determines actual sustainability classification
Eligibility indicates scope, while alignment indicates actual sustainability performance
What Companies Must Disclose
Under CSRD, companies must report taxonomy alignment metrics.
% of revenue aligned with taxonomy
% of capex aligned
% of opex aligned
Taxonomy disclosures link sustainability to financial metrics
These metrics allow investors to directly compare companies on sustainable economic exposure
Companies may show low current alignment but high taxonomy-aligned capex, indicating transition toward sustainability
Key Financial Mechanisms
The EU Taxonomy affects companies and investors through specific financial mechanisms.
1. Capital Allocation Mechanism
Capital flows toward aligned activities
→ Investment shifts to sustainable activities
2. Investment Screening Mechanism
Investors use taxonomy for decisions
→ Sustainable fund screening and selection
3. Valuation Mechanism
Aligned assets may receive premium
→ Potential valuation uplift for aligned activities
4. Regulatory Mechanism
Required for compliance and disclosure
→ CSRD reporting requirement
Financial Outputs:
• Capital inflows/outflows - investment toward aligned activities
• Inclusion/exclusion from funds - screening and selection
• Premium/discount - valuation impact for aligned assets
• Mandatory disclosure impact - regulatory compliance
Real Financial Pathways
The EU Taxonomy affects financial outcomes through concrete cause-effect chains.
Capital Flow Pathway
Taxonomy Alignment → Investor Preference → Increased Investment → Lower Cost of Capital
Screening Pathway
Non-Aligned Activity → Exclusion from Sustainable Funds → Reduced Capital Access
Valuation Pathway
High Alignment → Perceived Lower Risk → Valuation Premium
Compliance Pathway
CSRD Requirement → Taxonomy Disclosure → Reporting Impact → Cost / System Impact
Strategic Shift Pathway
Low Alignment → Strategic Transition → Capex Reallocation
Transition Pathway
Low Alignment → Increased Sustainable Capex → Future Alignment → Improved Capital Access

Challenges & Limitations
EU Taxonomy implementation presents technical and analytical challenges.
Complexity of criteria
Data requirements
Interpretation challenges
Sector coverage gaps
Partial coverage - Not all economic activities are fully covered by taxonomy
Implementation requires detailed technical and financial analysis
Key Takeaways
EU Taxonomy defines what is environmentally sustainable
It is a classification system used in regulation and finance
Requires meeting strict criteria (contribution + DNSH + safeguards)
Links ESG to financial metrics (revenue, capex, opex)
Influences capital flows and investment decisions
Critical for CSRD compliance
EU Taxonomy defines what is sustainable—and therefore where capital flows.
