‍

The EU Taxonomy might be considered an extra complexity for those already committing to the Corporate Sustainability Reporting Directive (CSRD). However, the right EU Taxonomy reporting software can easily be integrated into a workflow that delivers benefits beyond compliance with the latest EU regulations.

The EU Taxonomy is designed to guide investors and companies of all sizes toward more sustainable activities. This framework helps companies and stakeholders identify which economic activities (e.g., projects and investments) are environmentally sustainable. In this article, we’ll go through the five best EU Taxonomy reporting software tools, each with a slightly different angle. 

Quick recap: What is the EU Taxonomy, and why is it important?

The EU Taxonomy is a classification system designed to help businesses determine which economic activities are environmentally sustainable. To make sustainability a more tangible objective, there needs to be a consistent way of measuring what the EU considers sustainable–the EU Taxonomy contributes significantly by standardizing reporting across businesses.

The EU Taxonomy Regulation (Regulation (EU) 2020/852) legally enforces how a plethora of European (and some non-European) organizations present their alignment with the EU Taxonomy classification system. In short, both the classification and regulation are essential to keep everyone on the same page–and accountable.

How does the EU Taxonomy relate to the CSRD?

The EU Taxonomy and CSRD represent two sides of the same coin: a robust sustainability reporting framework in the EU. The EU Taxonomy concerns itself with which economic activities are sustainable based on clear criteria, with the CSRD stressing how entities must report on them, including which KPIs to include and whether an activity is aligned or simply just eligible.

Why using EU Taxonomy reporting software is worth the investment

Are you looking to save time and create audit-ready reports that give you the best indication of your sustainability performance? If this is the case, EU Taxonomy reporting software is a no-brainer.

These digital tools have all the benefits you’d expect, including significant time savings, iron-clad statistics for confident compliance, and automatic updates to keep you in check with the latest regulations. However, there’s more to reporting software tools than the nuts and bolts of compliance.

Using EU Taxonomy reporting software gives you and your stakeholders confidence in your numbers, which invariably provide you with a more accurate picture of your sustainability practices, progress, and areas for improvement. 

Research by the European Commission has shown that, on average, 20% of companies’ capital investments are aligned with the EU Taxonomy. That’s already a significant portion of expenditure that’s deemed sustainable and a lot for companies to highlight when talking about their corporate sustainability efforts.
