EU Taxonomy

The EU classification system for defining environmentally sustainable economic activities.

The EU Taxonomy is a classification system established by the European Union that defines which economic activities can be considered environmentally sustainable. Its primary purpose is to direct capital flows towards green investments and prevent greenwashing. The taxonomy sets out six environmental objectives: climate change mitigation, climate change adaptation, sustainable use of water and marine resources, transition to a circular economy, pollution prevention and control, and protection of biodiversity and ecosystems.

For an economic activity to qualify as "taxonomy-aligned", it must make a substantial contribution to at least one of the six objectives, do no significant harm (DNSH) to any of the others, and meet minimum social safeguards based on the OECD Guidelines for Multinational Enterprises and the UN Guiding Principles on Business and Human Rights. Technical screening criteria define the specific thresholds and conditions for each activity.

CSRD-obligated companies must disclose the share of their turnover, capital expenditure (CapEx), and operating expenditure (OpEx) that is taxonomy-eligible and taxonomy-aligned. This taxonomy disclosure is an integral part of the sustainability report under ESRS E1 (climate change). For financial market participants, the taxonomy is also relevant for defining sustainable investment products under the Sustainable Finance Disclosure Regulation (SFDR).

Legal Basis

EU Taxonomy Regulation (EU) 2020/852; Delegated Regulation (EU) 2021/2139 (Climate Delegated Act); CSRD Directive (EU) 2022/2464; SFDR Regulation (EU) 2019/2088

Practical Example

An energy company invests in the construction of a new solar farm. To classify this investment as taxonomy-aligned, it must demonstrate that the activity makes a substantial contribution to climate change mitigation, meets the DNSH criteria for all other environmental objectives (e.g. land use and biodiversity impacts), and complies with minimum social safeguards regarding labour rights. The company documents this assessment in its sustainability report as part of its taxonomy disclosure, reporting what percentage of its CapEx is taxonomy-aligned.

FAQ

All companies subject to the CSRD are required to disclose their taxonomy eligibility and alignment as part of their sustainability report. Financial market participants under SFDR must also use the taxonomy to classify their investment products.
An activity is taxonomy-eligible if it is covered by the taxonomy's technical screening criteria in principle. It is taxonomy-aligned only if it also meets all the criteria — substantial contribution, DNSH, and minimum social safeguards. Eligibility is a precondition; alignment is the higher standard that qualifies the activity as sustainable.
Currently, the EU Taxonomy focuses exclusively on environmental sustainability across six objectives. A separate Social Taxonomy is under development but has not yet been formally adopted. The minimum social safeguards within the existing taxonomy provide a social floor but are not equivalent to a full social classification system.
