The Sustainability

Transitgas at work

In the course of the sustainable development of its business activities, Transitgas AG has always been committed to organizing its activities transparently and beneficially.

Construction and operation of the Transitgas transport system are based on compliance with statutory regulations with respect to safety and the environment, as well as on constructive working relationships with the appropriate authorities at federal, canton and community levels.

With this natural gas pipeline significant volumes of energy are being transported across Switzerland. It is not visible because it runs underground.

Thus it preserves the appearance of the landscape and does not pollute the environment. Transitgas AG recognizes the importance of soil conservation. The soil is in itself a habitat, a filter and a foundation and must therefore be protected.

Funding of Projects to Promote Sustainability


Transitgas AG funds specific projects for sustainable development in the fields of society, the environment and business.

Transitgas AG runs a funding programme to support sustainable development projects in the regions belonging to its gas transport system. The funded projects contribute to society, the environment and business in those regions.

An invitation for project applications is generally issued once a year. For information about the purpose, criteria, financing and decision-making, please see this information sheet (German only). Project applications can be submitted using the following entry form (German only).

Cut energy costs with LORALARM

Transitgas AG is promoting Energie Zukunft Schweiz AG’s LORALARM project. The project is geared towards the development of a monitoring system for solar thermal systems.

Energie Zukunft Schweiz found in 600+ random checks that a sixth of all solar thermal systems are not working properly. This often goes unnoticed. If systems are faulty, no reduction in CO₂ emissions is achieved because the heating is automatically activated. Working together with Energie Zukunft Schweiz, Transitgas is helping to achieve a reduction in CO₂ emissions through the monitoring of solar thermal systems. A sensor detects faults and enables the rapid repair of defective systems. The offer is targeted at municipalities, public authorities and building owners in the transport area covered by Transitgas AG.

«30 trees for Ruswil» Transitgas AG donates native tree species

The trees are financed by companies and private individuals. The company Transitgas AG, represented by Bernhard Hodel from Grosswangen, donated ten trees. He did not want to miss the opportunity to be present at the planting of the first tree: “As a gas compressor station, we deal with fossil energy. The ecological idea and balance is important for us and is gaining a lot of weight within the company. Because we are based in Ruswil, we are very happy to get involved in this project with conviction.”

Solar roof for the Gass barn Project

Transitgas is helping the Buttisholz energy cooperative implement a photovoltaic system on the roof of the Gass barn in Buttisholz. The barn and the other buildings are to be refurbished, re-purposed and made accessible to the general public.

Energy transition and security of supply

How is Transitgas tackling these two challenges?

The immense use of fossil energy sources enabled major technological progress in the past decades and made our current standard of living possible. Carbon dioxide emissions are, however, the cause of global climate change. To stop or at least curb those effects, climate neutral targets have been decided upon. Those can be attained if energy needs are met in the future using renewable energy sources. Transitgas AG has also devised solutions for decarbonisation. Which of those it sees as medium-term and which as long-term is highlighted below.


Wolhusen Waste Heat Recovery Plant Project

Previous projects: In the Wolhusen Tropical Centre, Transitgas has funded a greenhouse with a breeding facility for fish and plants that thrive in a warm environment. The necessary heat is generated using waste heat from the Transitgas AG compressor station.


Emissions and Waste Heat Recovery


The gas turbines used in the Ruswil compressor station are cutting-edge design with optimal emission and consumption figures, in order to protect the environment.


In addition to compliance with the provisions of the Clean Air Act, Transitgas AG endeavored to keep all other emissions as low as possible. Therefore, in the event of decompression in the Ruswil compressor station, quantities of natural gas released are not blown into the atmosphere, but automatically diverted into an intermediate storage facility, subsequently returned into the pipeline and thus recovered.


By operating waste heat recovery plants in the Ruswil compressor station, Transitgas AG makes also an important contribution to energy efficiency. The plants, which are unique in Switzerland, produce electrical energy from the waste heat of the gas turbines and feed it into the grid of the local electricity supplier. In addition to producing electricity, the waste heat recovery plants also produce hot water for the station’s own use.

Environmental Protection


Since the construction of the first gas pipeline through Switzerland, knowledge of ecological construction has increased enormously. When constructing the new pipeline, environmentally compatible technologies were utilized, as it was necessary to protect waters in general as well as plants and animals.

The carefully initiated re-cultivation measures carried out following laying of the pipeline, have restored the land to its original state.


The pipeline route was selected from various alternatives taking into account the aspects of environmental compatibility, transport safety and technical-economic feasibility.

During the course of the expansion of the transport system Transitgas AG encouraged the use of micro-tunneling technology (trenchless pipelay) which was instrumental in the crossing of numerous ecologically sensitive areas.
