EU Taxonomy: German Pfandbrief Banks use AI software Taxo Tool

Financial institutions in particular, as well as companies in the real estate industry, play a central role in the sustainable transformation of the economy. Quite a few of them have been active for many years in business areas that are considered sustainable and climate-friendly, for example in the financing of renewable energies, infrastructure projects such as hospitals, schools or energy-efficient buildings. For an economic activity to be classified as sustainable, it must meet the criteria of the EU taxonomy for sustainable investment. The taxonomy aims to steer financial flows towards ESG (Environment, Social, Governance) throughout the EU, to establish the assessment of environmental sustainability and to strengthen investor confidence in making green investments more transparent.

For the companies concerned, the process of checking taxonomy compliance involves a great deal of effort, because data must be collected that in many cases is not yet available or is constantly changing. The higher the data granularity of the information to be reported, the higher the implementation effort. In addition, the high complexity of the regulations poses a problem. In order to be able to carry out the legal tasks of EU taxonomy more easily, cheaply and efficiently, the clients of vdpResearch GmbH, which include Pfandbrief banks, credit cooperative institutions, savings banks, private banks as well as independent real estate valuers, can access, via their real estate valuation software, the AI solution “Taxo Tool” – a software for implementing EU taxonomy that was jointly developed by Bundesverband Öffentlicher Banken Deutschlands, VÖB, its subsidiary VÖB-Service and Dydon AI. The technology of the Taxo Tool is a highly efficient solution in the field of artificial intelligence to digitise and map information gathering, process implementation and reporting.

This includes automated data collection from various documents, such as energy certificates for real estate, the calculation of technical assessment criteria (e.g. CO2 emissions) in cases of missing or unavailable data, and the consideration of country-specific laws for buildings. In addition, assessments for climatic and geological risks to help companies develop effective mitigation and adaptation strategies. This will ensure that construction and real estate projects receive an accurate assessment of their environmental impact.

“The EU taxonomy sets high requirements for the energy efficiency of buildings. This should lead real estate companies to invest more in energy retrofitting of buildings in order to meet the regulatory requirements. The aim is to achieve a reduction in energy consumption and greenhouse gas emissions in the real estate sector,” explains Reiner Lux, Managing Director of vdpResearch GmbH.

Dr. Stefan Hirschmann, Member of the Management Board at VÖB-Service GmbH, adds: “Sustainable properties that meet the criteria of the taxonomy are likely to have a higher market value in the long term. The increasing demand for sustainable properties will give them a competitive edge in the market and should be more attractive to tenants, buyers, and investors.” The desire for complexity and cost reduction as well as for extensive automation and digitalisation of the taxonomy check is therefore currently very pronounced in the market. According to Hirschmann, many companies still underestimate the enormous effort required to implement the regulatory requirements of the EU taxonomy.

“Through the partnership with vdpResearch, we are once again significantly expanding the customer base of the Taxo Tool and are jointly creating a market standard,” says Dr. Hans-Peter Güllich, CEO of Dydon AI, who programmed the taxonomy software with his team. “Without IT support, adequate implementation of the taxonomy requirements is unlikely to be possible. The EU regulation is particularly demanding in terms of data input, reporting, and IT. “
