What does sustainability mean at the Freiburg University Medical Center?

On the way to a green clinic

Numerous approaches and projects are making the University Medical Center Freiburg more climate-friendly.

Sustainability is a central component of the corporate philosophy at Freiburg University Medical Center. As a signatory to Klimawin BW (formerly the WIN Charter), the University Medical Center has been driving forward the conversion to a sustainable hospital in terms of social, economic and ecological aspects for years. This topic page is dedicated in particular to ecological sustainability and presents approaches and projects that will make the university hospital more climate-friendly. After all, according to projections, the healthcare sector accounts for more than five percent ofCO2 emissions in Germany.

"We are aware of the great responsibility that hospitals bear as energy-intensive facilities - after all, climate protection is a matter of living health protection," says Professor Dr. Frederik Wenz, Chief Medical Director of the University Medical Center Freiburg.

Great efforts are being made in many areas to implement sustainability in the medical field, administration and infrastructure of the University Medical Center Freiburg.

"We are well on the way to becoming a sustainable hospital, but we still have a long way to go," says Wenz. "Our 15,000 employees are an important factor in our success by acting in a climate-friendly way themselves and using their innovative ideas to make the University Medical Center fit for a sustainable future."

Sustainability as a strategy

In its sustainability strategy adopted in 2025, the University Medical Center Freiburg describes its vision for environmentally conscious healthcare, defines five development areas for sustainable development and sets out three focus topics to be pursued more intensively by 2030.

Klimawin BW

Sustainable in three dimensions

The University Medical Center Freiburg should act economically, ecologically and socially. In 2019, it made a clear commitment to economic, ecological and social responsibility by signing the Klimawin BW (formerly WIN Charter).

Promoting sustainable thinking and action is the aim of the charter of the Baden-Württemberg Sustainability Initiative (WIN). In twelve guiding principles, the Klimawin Charter describes the participating institutions' understanding of sustainability, which includes topics such as human rights, social and environmental concerns, sustainable and fair finances and the fight against corruption as well as regional added value.

The "Freiburg University Hospital Forest"

The Freiburg University Hospital forest is being created

Freiburg University Medical Center focuses on sustainable reforestation

In mid-April 2023, employees of the University Medical Center Freiburg reforested a fallow forest area in Burg-Höfen near Kirchzarten. Some children from the hospital's own daycare center also helped out diligently. The University Medical Center donated the deciduous and coniferous trees to the sustainable reforestation project, making an important contribution to protecting nature and the climate.

From maple to Douglas fir: diversity instead of monoculture in the new hospital forest

Instead of a monoculture, a mixed forest of maple, sweet chestnut, bird cherry and Douglas fir will grow in the Freiburg University Hospital forest in future.

  • The University Hospital donated 1,000 trees for the sustainable reforestation of an area of woodland that had been lying fallow.
  • 500 trees were planted by employees together with children from the hospital's own nursery.

"I try to act as sustainably as possible - for the children who still have their whole future ahead of them," says Frank Jentsch, who is responsible for food purchasing in the University Hospital's staff canteen and places particular value on regional and organic products.

Technology

Full steam ahead towards a green future

Generating and using electricity, cooling and heating in the most climate-friendly way possible: Numerous employees at the University Medical Center Freiburg use their expertise and good ideas to achieve this. The teams from Division 5 - Technology in particular are looking for new potential savings and adapting systems in over 160 buildings, devices and processes. More...

Hidden climate killers in the OR

Replacing and recycling anesthetic gases makes operations significantly more climate-friendly.

Many anesthetic gases used in operations today are real climate killers. Desflurane, which has around 2,500 times more impact on the climate than carbon dioxide, is considered particularly harmful. "A six-hour operation with desflurane is comparable to a trip from Freiburg to South Africa," says Prof. Dr. Hartmut Bürkle, Medical Director of the Department of Anaesthesiology and Intensive Care Medicine at the Freiburg University Medical Center. This is why Bürkle and his team have been developing more climate-friendly anesthesia procedures for many years. "Our strategy is to avoid and recycle," says Bürkle.

For example, desflurane has been replaced by less harmful anaesthetics throughout the hospital. Thanks to specially developed minimal flow techniques, significantly less anaesthetic gas is also used while maintaining the same level of safety for patients. "Thanks to the procedures we have established, the climate effect of a six-hour operation is reduced to a trip to Emmendingen," explains Bürkle. In addition, anaesthetic gases are collected in a filter directly in the operating room at the Bad Krozingen site and can later be completely recycled. Work is currently underway to introduce this system at the Freiburg site.
