A healthy environment is something that is near & dear to us

We value sustainability. As a modern, ecologically minded company, we take responsibility and are actively committed to protecting the environment.

The Swiss myclimate foundation is committed to protecting the environment in a way that has a sustainable impact. The organisation offers help in reducing and compensating for these climate-changing emissions. It promotes the use of renewable energy and energy-efficient technologies.

Compensation for emissions takes the form of ambitious myclimate environmental protection projects around the world to minimise the emissions of greenhouse gases, thereby directly protecting the environment. Climate protection projects not only reduce climate-impacting emissions, they also contribute to the sustainable development in project regions.

All rooms at Multimedia Networks AG are heated using low-CO2 wood chip heating. By using this ecologically-friendly system, Multimedia Networks AG is making a direct contribution to a healthy environment.

The servers at the individual data centres of Multimedia Networks AG are powered exclusively with energy from renewable sources. The green energy is generated from 100 percent CO2-free and environmentally-friendly hydropower. From an ecological standpoint, energy generated from flowing water is one of the least damaging forms of power generation.

Theodora Foundation

A hospital stay is a difficult experience for a child. The child is cut off from regular contact with his or her family and friends and must come to terms with unfamiliar and often very severe surroundings. The hospital clowns from the Theodora Foundation help put smiles on the faces of children. Hoststar thinks this is an exceptionally creative idea and therefore supports the Theodora Foundation with a donation.
