Measure and improve
ESG Data
The Komax Group’s ESG performance is comprehensively measured to identify where it can have the greatest impact and to define realistic targets.
CO₂ emissions and energy consumption
Reducing impact
In 2025, the Komax Group was responsible for total emissions of 5,835 tCO₂e (2024: 6,542 tCO₂e), of which 47.6% (2024: 46.4%) came from its own sources (Scope 1) and 52.4% (2024: 53.6%) from purchased energy (electricity and district heating – Scope 2). Overall, the Komax Group succeeded in significantly reducing emissions by 707 tCO₂e in 2025 compared to the previous year, which corresponds to a reduction of 10.8%.

1 The calculation basis for the various reporting years has been slightly adjusted to further improve data quality.
2 The greenhouse gas inventory was prepared in accordance with the Greenhouse Gas Protocol.
3 Heating and fuel, own energy sources. Emission factors from “DEFRA” were used for the calculation of emissions from heating fuels and motor fuels.
4 Electricity and heat. Emissions for 2025 and 2024 are reported as “market-based.” The corresponding emission factors come from local electricity suppliers. Previous emissions are reported as “location-based” using IEA emission factors.
5 The intensities for 2025 and 2024 are reported according to the “market-based” approach, previous figures according to the “location-based” approach using IEA emission factors.
The greatest lever for the Komax Group as it seeks to reduce its CO₂ emissions (Scope 1 and Scope 2) is the consumption of energy at its sites. There, it is striving to rely more on renewable energies such as solar energy or water power, and to replace fossil energy sources with CO₂-neutral solutions. It made enormous progress. In 2025, 58% of the electricity consumed came from renewable energy sources, which is almost double the previous year (2024: 31%) and an increase of 35 percentage points compared to the base year 2023 (23%).

Material usage and waste
Lean management and recycling
On the production side, the Komax Group strives to increase its energy efficiency on an ongoing basis. Highly automated, state-of-the-art production systems are used for the strategically important components that the Komax Group manufactures in-house. The production systems are based on lean management concepts, which are designed to avoid errors and minimize waste. However, total material consumption depends heavily on demand.
In 2025, the Komax Group’s waste volumes increased by 7.7% for various reasons. These include, for example, plant closures. To improve data quality, since 2024 the Komax Group has distinguished between recycled, i.e., reused materials, materials that are incinerated for energy recovery, and materials that are finally sent for disposal. The recycling and energy recovery rate therefore includes both recycling methods.
