CMS - Sustainability
"We need to set high goals even though they may seem impossible, but it is our obligation to our children and future generations. Legal requirements are not enough to achieve this." (Sustainability Coordinator CMS)
Under the guiding principle "Wheels into Future", we have been strategically committed to sustainability for over 10 years.
Despite our growth strategy, the environment and social components have been among our central issues from the very beginning.
We see it as our responsibility to lead the way with a sustainable growth model. We define clear quantifiable goals and involve all stakeholders in the value chain.
We are proud to have already achieved a lot:
- Saving raw materials
- Reduction of environmental impacts, especially energy consumption and greenhouse gas emissions
- Reduction of water consumption, e.g. through waste water management
- Reduction and recycling of waste, especially aluminium waste and aluminium chips
- Creating a healthier working environment for employees
Simply by choosing suppliers that use renewable energy sources, the carbon footprint can be reduced by 40%. We have a 5-year plan to reduce CO2 emissions by 15% compared to 2020.

CMS Aero - energy efficient designs
Hybrid and electric vehicles demand new ideas from wheel designers. As an original equipment manufacturer for leading automotive brands, CMS is intensively researching solutions that achieve a perfect balance between effective weight and aerodynamics.
For this purpose, the resulting wheels C29-Aero and C32-Aero were tested in comparison with a conventional double-spoke design by an independent commission of the Technical University of Dresden. The test was intended to illustrate driving at interurban and motorway speeds, so a speed range of 80 to 130 km/h was set in 10 km/h increments. In order to simulate the wind not only from the front but also from the side, the angle of the flow was varied between 0° and 25°.
The result confirms: The more closed a wheel is, the more clearly the drag coefficient decreases with increasing speed. Thus, the extra high rim shoulder of the C29-Aero achieves an improved CW-value of up to 5% compared to a conventional double-spoke design. On the almost fully closed C32, the CW-value is reduced by up to 16% and by 14% on average.
A result that can be built upon further...
