About iwis

iwis is a leading company for high-precision components and systems in the automotive and industrial sectors. As a global partner, iwis develops and manufactures innovative solutions for a wide range of industries, including automotive, mechanical engineering, packaging, printing, food, photovoltaics, and many others.Sustainability is a central part of iwis’ corporate management, integrating social, environmental, and economic aspects. In addition to CO₂ reduction, energy-efficient production, and recyclable materials, iwis promotes environmental awareness through training and incorporates environmental considerations already in the product development stage. The company’s goal, as defined in its climate strategy “ZeroCarbon 2040”, is to achieve CO₂ neutrality in Scope 1 and 2 by 2040 and to significantly reduce Scope 3 emissions.

Initial situation and sustainability measures

At the main sites, a software solution for environmental management and occupational safety had already been implemented. However, an integrated solution for calculating the Corporate Carbon Footprint (CCF) and Product Carbon Footprint (PCF) was still missing. To meet the CSRD requirements, the company sought support from an external consulting firm. Data collection in Excel caused a high manual workload, particularly for the double materiality assessment and reporting.

Challenges

• Data collection: The use of Excel spreadsheets made structured communication with international sites difficult. As a result, data collection was not only complex but also time-consuming. Feedback from abroad led to numerous email exchanges for clarification and validation of the data.
  

• CCF and PCF calculation: Between 2022 and 2023, iwis developed a transformation concept based on the GHG inventory of all German sites. However, a tool for the global implementation of best practices—without relying on Excel—is still lacking.
  

• CSRD reporting: Implementation was carried out with external consulting support. However, a modern tool for embedding knowledge and processes internally is still missing.

Why iwis chose Tanso as its sustainability software

Tanso convinced with the combination of an integrated platform for all relevant requirements and personalized support from experts. The software brings together the collection and calculation of the Corporate Carbon Footprint (CCF) and Product Carbon Footprint (PCF) with the requirements of CSRD reporting in one holistic system. This makes it possible to leverage synergies, avoid duplicate work, and efficiently use CO₂ calculations for various reporting obligations. Compared to Excel-based calculations, Tanso enabled product- and site-specific CO₂ accounting for the first time—without manual workarounds.

„Tanso is our central solution for carbon accounting and ESG management – a platform that seamlessly integrates CCF, PCF, and CSRD, creating synergies where duplicate work was previously required.“

Another important aspect was the comprehensive coverage of regulatory requirements: With the integrated modules for the EU Taxonomy and CBAM, Tanso offers a future-proof solution that enables iwis to centrally manage all sustainability obligations on a single platform—without the need for additional software or external consulting.

„To leverage sustainability as a strategic success factor, reliable data is essential. Tanso provides the necessary foundation to systematically measure sustainability, manage it effectively, and ultimately achieve long-term competitive advantages.“

Results achieved through the use of Tanso software

Intuitive usability, AI-powered emission factor mapping for CCF & PCF, and automated text modules, combined with direct integration into ESRS standards, ensure that all relevant information is centrally available and reporting is significantly simplified. Transparent dashboards and clearly assigned tasks not only support operational implementation but also strengthen company-wide awareness of sustainability and responsibilities.

Existing CCF data can be seamlessly transferred into the CSRD report and automatically further processed. For example, a complete CSRD test report was created within just two months.

The clear structure enables all user groups—from sustainability managers to auditors—to efficiently capture and review data. At the same time, the early involvement of relevant stakeholders reduces inquiries by an average of one third and prevents unnecessary duplication of work.

"Task management in Tanso is very user-friendly, and features such as date control and approval status support us effectively. As a result, we were able to reduce the time required to create the first CCF by 30% and the second CCF by as much as 60%.”

Further Key Results:

• Flexible Emission Factor Management: Specific emission factors can be seamlessly integrated and updated at any time, with adjustments automatically applied.
• Significant Time Savings: By duplicating existing inventories, new CCFs can be created much faster. Processing time was reduced by around 30% for the first CCF and by up to 60% for the second.
• Analytics as a Basis for Management Decisions: Mobility and energy-saving measures are systematically evaluated by location, with clearly identified CO₂ reduction potentials serving as a central criterion for budget decisions.

Outlook

iwis plans to capture the CO₂ emissions of all sites in much greater detail this year, further expanding the depth of its data. Following its registration with the SBTi, the next step will be the verification of its climate targets. Tanso will serve as the central tool in this process – particularly for the precise calculation of emissions, the definition of reduction targets, and the continuous monitoring of progress.
