TAXO TOOL & EU Taxonomy

The AI-powered solution enabling financial institutions and corporates to assess the alignment with the EU Taxonomy



The introduction of the EU Taxonomy represents an important step of the EU towards managing sustainable investments and reducing the CO2 emissions. 

But in terms of challenges, the EU taxonomy is a new and mammoth regulatory project determining a significant increase of bureaucratic costs.

Secondly, companies often are not able to collect enough data and are missing the abilities to evaluate and elaborate them.

The legislative documents contained in the EU’s taxonomy regulation alone make up a total of 30.000 pages. In addition, access to a variety of publicly available data sources is required to calculate carbon emissions and energy consumption figures. The financial sector needs a technical solution to be able to handle the wealth of data and information on the one hand and to make decisions forwarding the aim of a sustainable financial sector on the other.


_Advantages of the TAXO TOOL

#1 Strong Knowledge Base

We have our own CO2 emission data base. It consists of procedural models, which also enable an assessment if basic data are not fully available.

#2 Transparency & Auditability

Our approach is “open-box”, that means the results of the AI-Suite are all fully transparent and auditable. The whole path back to the root of the topic is available and traceable.

#3 Sharing costs

Any further development of the solution is done centrally and rolled out to all the banks and companies, enabling a sensitive cost reduction.

#4 Fast implementation

Our solution enables a fast implementation of the EU-Taxonomy through automated processes based on AI technology. As a result, your company is getting compliant with less effort and costs.

#5 Always up to date

Any regulatory change will be automatically integrated within the solution, with no extra worry on your side.

#6 Ready-to-go

The AI-Suite is immediately available thanks to cloud computing (SaaS) or an on-premise solution.


The TAXO TOOL is mainly addressing banks and saving banks, but applies also to insurance and investment companies, fund managers and other industries and institutions falling under this new regulation.

_AI Solution for Sustainable Finance

The TAXO TOOL, developed in collaboration with Bundesverband Öffentlicher Banken Deutschlands (VÖB), and VÖB-Service GmbH, solves this data problem by using artificial intelligence.

Our ready-to-go AI platform supports data collection and document capture. This means that there is no need for institution-specific development. This reduces costs significantly and increases efficiency.

The aim of the TAXO TOOL is to map the complexity of the technical evaluation criteria of the EU taxonomy for sustainability in one system and to enable automated procedures.

Transparency and auditability of the results are key elements in our AI Suite. Our approach is “open-box”, that means that we present the whole path that brought to a certain result.

Indeed, transparency requirements are imposed on reporting companies, which are to be fulfilled by disclosures.

Our 3 AI steps to apply the EU Taxonomy

We created a logic representation of the EU Taxonomy for each Economic Activity out of 30.000 pages.


We developed CO2 emission models based on process engineering to overcome the lack of data, especially the case for SMEs.


We automated document reading and data capture with our Natural Language Processing (NLP) stack.
