The rules governing EU taxonomy alignment reporting in 2026 look very different from what companies anticipated just two years ago. A sweeping Omnibus simplification package, a new Delegated Act, and a narrower scope have reshaped who must report, what they must disclose, and how much detail auditors will expect to see. If your organisation is working through these obligations right now, or trying to understand whether the recent changes actually reduce your workload, this guide covers the state of play as of mid-2026, including the one piece of the puzzle that regulations never quite spell out: what credible product-level carbon data looks like underneath a taxonomy-aligned claim.
Key Takeaways
- From 2026, alignment reporting extends to all six environmental objectives, including water, circular economy, pollution, and biodiversity, not just climate change.
- The Omnibus Directive has narrowed the CSRD scope to EU entities with over 1,000 employees and net turnover exceeding €450 million, which directly determines who must report under Article 8 of the Taxonomy.
- A new materiality threshold lets companies exclude activities representing less than 10% of turnover, CapEx, or OpEx from detailed reporting, while simplified templates cut data points by approximately 64% for non-financial undertakings.
- A persistent gap between eligibility and alignment remains across European companies, largest for CapEx at 30 percentage points, indicating that many activities fall short of technical screening criteria and “Do No Significant Harm” tests.
- Product-level carbon footprints, calculated under ISO 14040/44, are becoming the underlying evidence layer that makes taxonomy KPIs auditable and defensible.
What the EU Taxonomy Actually Requires in 2026
The Six Objectives and the Alignment Test
The EU Taxonomy provides a common language and framework to determine which economic activities qualify as environmentally sustainable, in line with European Green Deal objectives. It was established through Regulation (EU) 2020/852 and serves as a central tool to guide capital flows towards sustainable investments and to increase transparency across markets.
To pass the alignment test, an activity must clear three hurdles simultaneously. First, it must make a “Substantial Contribution” to at least one of the six environmental objectives, meeting specific Technical Screening Criteria to prove that contribution. Second, it must “Do No Significant Harm” to any of the other five objectives, which prevents a company from claiming an activity is sustainable if it achieves one goal at the expense of another. Third, the company must comply with minimum social safeguards based on the OECD Guidelines and UN Guiding Principles on Business and Human Rights. The six environmental objectives are: climate change mitigation, climate change adaptation, sustainable use and protection of water and marine resources, transition to a circular economy, pollution prevention and control, and protection and restoration of biodiversity and ecosystems.
The Expanded Scope of Alignment Reporting
The EU Taxonomy reporting requirements roll out progressively: in 2025, all CSRD entities had to report activities’ eligibility for all six taxonomy objectives, and alignment only for climate. From 2026, alignment reporting extends to water, circular economy, pollution, and biodiversity objectives. This is a significant expansion. Many organisations that had solid processes for climate-related KPIs are now discovering that the non-climate objectives require fundamentally different data, particularly for pollution prevention and circular economy criteria, which often demand product-level lifecycle information rather than corporate-level energy figures.
The New Simplified Delegated Act
Commission Delegated Regulation (EU) 2026/73, published in the Official Journal on 8 January 2026, marks a significant step in implementing the EU Taxonomy, amending earlier Delegated Regulations to simplify the content and presentation of disclosure requirements and streamline certain technical screening criteria. The Delegated Regulation entered into force on 28 January 2026 with retroactive application from 1 January 2026 for reports covering the 2025 financial year, though companies may opt to defer and apply the previous regime for 2025 if more convenient.
The practical relief this provides is real. Template revisions consolidate disclosures into one summary and up to three per-activity tables, covering turnover, CapEx, and OpEx, reducing fields by 64%. A new materiality principle means activities that cumulatively make up less than 10% of turnover, CapEx, or OpEx can be excluded from KPI calculations as not financially material, and the entire OpEx KPI can also now be excluded from reporting when OpEx is not material to an entity’s business model.
How the Omnibus Changes the Landscape
The Omnibus Directive was published in the Official Journal of the European Union on 26 February 2026, following its official adoption by the Council on 24 February 2026, and is the outcome of an agreement reached in December 2025 on the European Commission’s simplification proposal.
The most consequential change for taxonomy reporting is the revised scope threshold. In future, only companies with more than 1,000 employees and a turnover of more than €450 million will have to submit a sustainability report in accordance with the CSRD, significantly reducing the number of companies required to comply. Previously, two of three criteria had to be exceeded: more than €50 million in turnover, more than €25 million in total assets, or more than 250 employees.
As in the current CSRD, only companies within the proposed scope of CSRD reporting will be required to report under Article 8 of the Taxonomy Regulation. If you fall outside the new thresholds, mandatory taxonomy disclosure drops away. But this does not mean the taxonomy becomes irrelevant for smaller companies. Non-EU companies and smaller firms face taxonomy requirements indirectly through their EU subsidiaries’ reporting obligations, through SFDR requirements on financial products, and through EU customers and partners that need taxonomy data for their own reporting. The taxonomy’s influence on global capital flows means that non-EU companies increasingly benefit from demonstrating alignment.
Meanwhile, the Commission is not standing still on technical criteria. On 17 March 2026, the European Commission published proposed amendments to the EU Taxonomy’s Climate and Environmental Delegated Acts, containing widespread revisions of activity descriptions and Technical Screening Criteria. The Commission aims to adopt the amendments by mid-2026, after which a scrutiny period of up to six months means they could enter into force by 1 January 2027 and apply from 2026 reporting periods, with no transitional reliefs currently proposed. Companies working on this year’s reports need to track that timeline carefully.
The Eligibility vs. Alignment Gap: Why It Matters
One of the most revealing statistics to emerge from the first wave of taxonomy disclosures is how wide the gap between eligibility and alignment actually is in practice. Average eligibility rates among reported companies sit at 36% for turnover and OpEx, and 46% for CapEx. Average alignment rates, however, are just 10% for turnover, 16% for CapEx, and 12% for OpEx.
A common error is confusing eligibility with alignment and reporting a high eligibility percentage as though it indicates strong environmental performance. These are very different things. Eligibility simply means an activity is described somewhere in the taxonomy. Alignment means it has cleared the Technical Screening Criteria and the DNSH tests. The gap is where compliance work actually lives.
Many organisations have found that limited awareness and technical understanding among staff have led to inconsistent reporting and a cautious approach to alignment assessments. Part of the reason for this caution is that the DNSH criteria, particularly for objectives like pollution prevention and circular economy transition, require granular data about products and processes that most corporate reporting systems were never built to capture.
Why Product Carbon Footprints Are Central to DNSH Evidence
This is the hidden connection that many taxonomy guides overlook. Demonstrating “Do No Significant Harm” to climate change, for instance, requires evidence about the carbon intensity of your activities and products, not just a corporate-level renewable energy percentage. That evidence increasingly comes from ISO 14040/44-compliant life cycle assessment.
Consider what taxonomy alignment actually demands for a manufacturing company. The activity must not only make a substantial contribution to, say, circular economy objectives, but must also demonstrate it does no significant harm to climate change objectives. That cross-objective check requires product-level carbon data. And the numbers can be counterintuitive.
Take the carbon footprint of a safety equipment container, calculated by Devera using Monte Carlo LCA under ISO 14040/44. The median footprint is 4.47 kg CO₂e per kilogram, with a wide range from 3.34 to 6.90 kg CO₂e. Crucially, 57.5% of that impact falls in raw materials and 35.9% in manufacturing, meaning that claims of circular economy alignment, which might focus on end-of-life recyclability, need to be cross-checked against upstream carbon intensity or they will fail the DNSH climate test. A product landing at the higher end of that range (near 6.90 kg CO₂e/kg) faces a very different alignment conversation than one at the lower end.
The same logic applies in consumer goods. Devera’s benchmark for a body cream shows a median of 2.50 kg CO₂e per container, ranging from 1.78 to 3.85 kg CO₂e, with raw materials accounting for 47.7% of impact and packaging for 17.1%. A cosmetics manufacturer claiming taxonomy alignment under circular economy criteria would need to demonstrate that the packaging and formulation choices that reduce end-of-life impact do not simultaneously drive up the raw materials carbon burden. Without an LCA that quantifies those phase-level trade-offs, the DNSH assessment has no numerical foundation.

KPIs, Templates, and Practical Reporting Steps
The Three Core KPIs
For non-financial undertakings, Article 8 mandates the disclosure of three KPIs: turnover, CapEx, and OpEx. The turnover KPI measures the proportion of a company’s net revenue derived from products or services associated with taxonomy-aligned economic activities. The CapEx KPI focuses on investments in long-term assets and is calculated as the proportion of total CapEx related to assets or processes associated with taxonomy-aligned activities, signalling the extent to which a company is investing in greening its asset base.
The simplified templates introduced by Delegated Regulation (EU) 2026/73 consolidate these KPIs into fewer tables without changing the underlying calculation logic. The new materiality threshold is a practical relief for companies with diverse activity portfolios, allowing focus on what actually moves the needle financially.
Assurance Requirements
Assurance became mandatory for companies within CSRD scope from FY 2024, and 86% of reporting companies received limited or reasonable assurance. This surge exposed gaps in audit trails and data traceability, with many organisations unprepared for the level of evidence auditors required, especially for objectives beyond climate change. The move into non-climate alignment objectives in 2026 is likely to intensify auditor scrutiny further, since the data underpinning those assessments is less mature.
Recommended Reporting Table: Phased Scope Summary
| Company Category | Reporting Trigger | First Taxonomy KPIs Due |
|---|---|---|
| Large PIEs (Wave 1, NFRD scope) | Already reporting | FY 2024 data, published 2025 |
| Large EU companies (Wave 2, post-Omnibus threshold: 1,000+ employees, €450M+ turnover) | CSRD mandatory | FY 2025 or 2026 data (subject to national transposition) |
| Listed SMEs (Wave 3) | Voluntary until 2028 | First mandatory report due 2027, opt-out until 2028 |
| Non-EU companies with significant EU operations | CSRD Phase 4 | From 2028 if thresholds met |

Turning Alignment Reporting into a Strategic Asset
In 2025, businesses that adopted the EU Taxonomy saw improved credibility with investors and stakeholders, positioning themselves and enabling informed decision-making ahead of stricter regulatory requirements. An average of around 20% of all capital investments align with the taxonomy, with some industries seeing 60% alignment, according to the European Commission.
The companies closing that eligibility-alignment gap fastest are those treating carbon data as an operational asset rather than a compliance output. When your LCA data is structured, auditable, and product-level, it feeds directly into DNSH assessments, KPI calculations, and the narrative sections of your CSRD management report. It also supports green claims under the EU Green Claims Directive and underpins investor communications about forward-looking decarbonisation strategies.
Take another Devera benchmark to illustrate how this plays out: the T-shirt carbon footprint sits at a median of 3.01 kg CO₂e, with manufacturing accounting for 60.1% of total impact and raw materials 23.5%. For a textile company pursuing taxonomy alignment under circular economy criteria, the data immediately reveals that a recycled fibre strategy targeting raw materials is addressing only about a quarter of lifecycle impact, while the manufacturing phase dominates. The EY EU Taxonomy Barometer 2025 noted that the largest sectoral gaps between eligibility and alignment are in mobility, construction, and health and biotech, but any manufacturing sector faces the same challenge of translating activity-level eligibility into product-level evidence for alignment.

Frequently Asked Questions
What is the difference between taxonomy eligibility and taxonomy alignment? Eligibility means an economic activity is listed and described within the EU Taxonomy’s Delegated Acts. Alignment is a stricter standard: an eligible activity must also meet specific Technical Screening Criteria, demonstrate it does no significant harm to any of the other five environmental objectives, and comply with minimum social safeguards. Many companies report high eligibility rates but much lower alignment rates because clearing all three conditions simultaneously requires detailed, auditable evidence.
Which companies must report under EU taxonomy alignment reporting in 2026? Following the Omnibus Directive published in February 2026, mandatory taxonomy disclosure under Article 8 applies to companies within the revised CSRD scope: EU entities with more than 1,000 employees and net turnover exceeding €450 million. Companies outside these thresholds are not mandatorily required to report, though they may still face indirect pressure through their supply chains, investor requirements, or financial product classifications.
How does product-level LCA data support taxonomy alignment reporting? The “Do No Significant Harm” assessment requires companies to demonstrate that pursuing one environmental objective does not create significant negative impacts on the other five. This cross-objective check needs quantitative, lifecycle-based evidence at the product or activity level, not just corporate-level energy or emissions data. An ISO 14040/44-compliant LCA provides the phase-by-phase breakdown of where environmental impacts actually occur, which is the foundation of a credible DNSH assessment for manufacturing and product-linked activities.
What changed in the EU Taxonomy reporting templates for 2026? The Commission Delegated Regulation (EU) 2026/73, which entered into force on 28 January 2026 and applies retroactively from 1 January 2026, introduced simplified disclosure templates that reduce data points by approximately 64% for non-financial undertakings. A materiality threshold now allows companies to exclude activities representing less than 10% of turnover, CapEx, or OpEx from detailed reporting. Companies may also opt to defer these new rules by one year and apply the previous templates for the 2025 financial year instead.
