Manufacturing · EU Taxonomy Activity Guide

Low-carbon technology manufacturing under the EU Taxonomy

The manufacture of renewable energy technologies, hydrogen equipment, low-carbon vehicles, energy-efficiency components for buildings and other key low-carbon technologies qualifies as a family of enabling activities. The substantial contribution test is what the product does; the assessment substance sits in defining the qualifying product scope and in factory-level DNSH.

Activity ID

CCM 3.1 – 3.6

NACE code

C25 – C30 (various)

Objective

Climate change mitigation

Sector

Manufacturing

These are the Taxonomy’s flagship enabling activities: they qualify because their products enable emissions reductions elsewhere, from wind turbines to EVs to building insulation, rather than by meeting factory-level emissions thresholds.

Why this activity matters

Europe’s industrial strategy leans heavily on scaling clean-tech manufacturing, and the Taxonomy underwrites its financing: gigafactory-style investments, production line conversions and component supply chains all classify their CapEx and turnover through these activities. The family covers renewable energy technologies (3.1), hydrogen equipment (3.2), low-carbon transport technologies including zero-emission vehicles and their components (3.3), batteries (3.4, covered in its own guide), building energy-efficiency equipment (3.5), and other low-carbon technologies delivering demonstrable life-cycle savings (3.6).

The recurring assessment question is scope: which products, and which share of a mixed product portfolio, fall within the qualifying descriptions, because turnover and CapEx alignment follow that allocation. For 3.3 (vehicles and components) the qualifying vehicle definitions mirror the transport activities, and for 3.6 the catch-all, the evidence is a demonstrated life-cycle emissions saving versus the best available alternative.

What alignment requires

Purposive product-scope tests rather than factory thresholds. In summary:

Area	What is required (summarised)
Product scope (3.1-3.5)	The manufactured products fall within the qualifying descriptions: renewable energy technologies, hydrogen production/use equipment, low-carbon transport vehicles and components, or defined building efficiency equipment (insulation, efficient windows, heat pumps, controls and similar).
Catch-all (3.6)	Other technologies qualify where aimed at substantial life-cycle GHG savings demonstrated against the best performing alternative, evidenced by quantified comparison.
Allocation	Mixed manufacturers allocate: turnover and CapEx alignment follow the share of production within qualifying scope, product line by product line.

Summarised for orientation; the assessment itself applies the full criteria text of the Delegated Acts as amended.

Where DNSH scrutiny falls

Pollution & chemicals

Factory-level: restricted substances in products and processes, REACH compliance, and emissions permitting.

Circular economy

Product durability, reparability and recyclability documentation; production waste management.

Water

Process water use and discharge for the manufacturing site.

Climate adaptation

Site CRVA, standard for industrial facilities.

Documentation that typically supports the assessment

Product catalogue mapped to the qualifying descriptions
Revenue/production split by product line for allocation
For 3.6: the life-cycle comparison versus the best available alternative
Factory permits, chemicals compliance and waste management documentation
Product circularity documentation (durability, recyclability)

How Censatim assesses it

These assessments are scope-mapping exercises: our questioning walks the product portfolio against the activity descriptions, fixes the allocation basis, and then covers factory DNSH. The output, a defensible product-scope determination with an aligned share, is exactly what manufacturers need for CSRD KPIs and what lenders need for clean-tech financing.

Censatim is an expert-built EU Taxonomy assessment tool: describe the asset or activity in plain language, upload supporting documents, and answer a short set of targeted questions. The result is a criterion-by-criterion view with an In-line / Partial / Not aligned / Undetermined rating and a confidence level for each dimension. See the full methodology.

Frequently asked questions

What counts as low-carbon technology manufacturing in the EU Taxonomy?

The 3.1-3.6 family: renewable energy technologies, equipment for hydrogen production and use, low-carbon transport vehicles and their components, batteries, energy-efficiency equipment for buildings, and a catch-all for other technologies with demonstrated substantial life-cycle GHG savings.

Are these activities enabling under the Taxonomy?

Yes, explicitly: they qualify because their products enable emissions reductions in other activities, so there is no factory emissions threshold; the tests concern what is manufactured, not the plant’s own footprint (which DNSH still covers).

How does a mixed manufacturer calculate its aligned share?

By allocation: production is mapped product line by product line against the qualifying descriptions, and turnover and CapEx alignment follow the qualifying share, which is why the product catalogue and revenue split are the core assessment evidence.

What evidence does the 3.6 catch-all require?

A quantified life-cycle comparison showing substantial GHG savings versus the best performing alternative technology on the market, so an LCA-style analysis rather than a qualitative claim.
