The CURRENTA Group manages and operates one of the largest chemical parks in Europe: CHEMPARK, with sites in Leverkusen, Dormagen, and Krefeld-Uerdingen. Companies based there work under ideal conditions for research and production. The CURRENTA Group provides every essential on-site service from a single source, including a reliable supply of materials and energy, a wide range of top-tier analytical services, state-of-the-art environmental management, extensive infrastructure services, and dependable safety and security concepts.

Challenge
CSRD reporting means collecting a large volume of narrative content and quantitative datapoints across the organization, preparing it consistently, and documenting every step so the external auditor can follow it end to end. An organization like the CURRENTA Group runs into limitations pretty quickly when using Excel and Word.
Solution
Sunhat gives the CURRENTA Group one central Proof Platform where data collection and reporting are directly connected. Datapoints are collected once and used many times over: for the CSRD report, for ratings such as EcoVadis and GRESB, for the company's own questionnaires, and for internal reporting formats.
The Situation
Sustainability at the CURRENTA Group
As the operator of one of the largest chemical parks in Europe, the CURRENTA Group carries responsibility well beyond its own company. Energy supply, analytics, environmental management, infrastructure, and safety for the chemical companies based on site define the day-to-day operation. That same breadth shows up in its sustainability requirements.
The CURRENTA Group manages its sustainability reporting, external ratings, and internal reporting formats in one place. But the CSRD raised the bar sharply on scope, structure, and audit readiness. At the same time, expectations grew for statements that stay consistent and traceable across reports, ratings, and stakeholder requests.
The Challenge
CSRD Implementation with Excel and Word Can Only Go So Far
The CSRD requires a large volume of quantitative datapoints and narrative content to be collected across the organization, prepared consistently, and documented so the external auditor can follow it. At that level of complexity, standard office tools lose the thread. Evidence, ownership, and versions end up in different places. Follow-up questions run through long email chains. The same data gets collected more than once and stored wherever it lands.
So the CURRENTA Group looked for a digital application that creates a clear structure, covers the reporting obligations efficiently, and can eventually connect existing systems such as the double materiality assessment without adding maintenance work. One condition mattered throughout: the solution had to cover the requirements in full, with no custom development.

How Sunhat stood out
One Data Foundation, Many Reports
With Sunhat, the CURRENTA Group links the structured collection of quantitative data directly to the CSRD module for preparing the sustainability report. The result is a consistent, traceable data foundation that makes both the external audit and managing evidence for ratings noticeably easier.
The CSRD module lays out content, requirements, and responsibilities in a clear structure. That makes the whole process far easier to steer and coordinate, even across sites and departments. The interface is built so that people who work in the platform only occasionally can still contribute quantitative data and narrative content intuitively.
Proof AI takes on the writing work. Answers stay consistent from one report to the next, content and figures that are already prepared can be reused where they fit, and autofill draws on existing data to answer new requests precisely.

The Results
One Central Platform for CSRD, Ratings, and Internal Reports
Today the CURRENTA Group uses Sunhat as the data foundation for a wide range of sustainability work. Because collection happens centrally, several reports draw on the same source. Duplicate data collection disappears, and the team feels the gain in how much it gets through.
In use today:
CSRD reporting
Through the Sunhat CSRD module, with audit-ready documentation of every datapoint and every piece of evidence.
External ratings
Such as EcoVadis and GRESB, fed from the same data foundation as the CSRD report.
Responsible Care
And further standards-based reporting formats required internally, all held centrally in Sunhat.
Custom questionnaires
For internal and external stakeholder requests, answered consistently across reports and formats.

"Instead of losing ourselves in email chains, every datapoint comes together in one place. That way, we can use information across different reports and respond more quickly to requests from investors, customers, and the public. And the new AI features in Sunhat? They bring real efficiency to the work, for example, the autofill function, which delivers precise answers based on the data and information we already have."
"Sunhat impressed our CURRENTA Group sustainability team with its seamless integration of data collection and reporting, as well as its flexible and user-friendly approach to engaging relevant stakeholders. The holistic, forward-looking approach to efficiently structuring various reporting systems and ratings, as well as the Sunhat team’s high level of subject-matter expertise, were ultimately the key factors in our decision.”
