Through the alignment of its climate goals to the SBTi, Strategic Sourcing and Sustainability teams of the CABB Group are working on supplier engagement to reduce suppliers’ carbon footprint and identify potential alternative renewable materials. Continuous improvement of production processes and targeted investments in process technology are an essential part of driving innovation in production and optimize energy use. Last but not least, the conscientious use of water and the safe handling of environmentally critical materials and wastewater are relevant topics and regularly monitored.

When comparing the annual data with previous years, it should be considered that this brochure uses 2022 as the new base year for environmental key figures. The base figures were calculated without the Galena site.

The CABB Group’s SBTi roadmap started in November 2024, having its near-term climate goals validated in 2025. As a result, the following initiatives have been implemented:

• Position the CABB Group as a sustainable business partner and create a competitive advantage by supporting customers to deliver on their ambitious climate targets.
• Invest in an increasing share of green electricity as an opportunity to reduce emissions and risks related to CO2 tax in the future.
• Expand the CABB Group’s supply base to innovative providers of renewable materials that also reduce CO2-related financial risks in the long term.

Emission Calculation and Achievements in 2025
As in previous years, the GHG emission calculation has been done in line with the GHG Protocol Corporate Standard. In 2025, for the first time, all categories of Scope 3 emissions were calculated.

Compared to 2022, the CABB Group was able to decrease its total CO2 emissions by 23%. This reduction was driven by multiple factors, including proactive energy efficiency initiatives resulting in a significant decrease in related energy consumption (Scope 2) and raw material usage (Scope 3). Additionally, various energy efficiency projects across all our sites – described in the following chapters, in detail in chapter 2.4 – played a key role in this achievement.

Product Carbon Footprint
The first Product Carbon Footprint (PCFs), back in 2023, has been conducted for chlorine, caustic soda and hydrogen. This has been done in line with DIN EN ISO 14067 and the “Together for Sustainability” (TfS) guideline for PCFs. To prove the validity of these PCFs, an external assessment has been performed in the form of audits by TÜV. In 2025, the Gersthofen site in Germany achieved the “ISCC PLUS and ISCC EU RFNBO” certifications for the first time, for multiple low-carbon products and green hydrogen production. The ISCC EU RFNBO certification scheme verifies compliance with the EU’s legal requirements for sustainability and greenhouse gas emissions savings criteria for renewable fuels, as well as the production of electricity, heating and cooling from biomass.
