We make our contribution to the energy turnaround in order to enable our society, our children and grandchildren a future worth living on this planet.

As a company, we are committed to the careful use of resources in the areas of energy generation, energy distribution and water technology and place the saving of CO2 emissions at the forefront of all our activities.

Our commitment to clean technologies

The United Nations Framework Convention on Climate Change was adopted in New York City on May 9, 1992, and signed by 154 countries at the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro that same year.

In order to avoid a dangerous disruption of the climate system, greenhouse gas concentrations should be stabilized, because we only have a certain greenhouse gas budget at our disposal.

In order to permanently limit average global warming to a tolerable level compared to pre-industrial times, a rapid reduction of global greenhouse gas emissions and CO2 emissions from fossil energy sources is therefore necessary.

From 100 to 0

In connection with the climate crisis only two numbers are important! The emission of 51 billion tons of greenhouse gases per year or 35 billion tons of released CO2 emissions from burned fossil energy sources must be reduced to 0 in the next few years.

To ensure that global warming does not exceed 1.5 °C compared to pre-industrial times, we have considerably less than 10 years to achieve this before the concentration of greenhouse gases in the atmosphere reaches a level that will have serious consequences for global warming.

However, emissions from burning fossil fuels (about 35 billion tons/year) have doubled in the last 50 years and account for the largest share of global CO2 emissions (42 billion tons/year), along with other greenhouse gas emissions that are harmful to the climate (51 billion tons/year).

The following chart illustrates the development of global greenhouse gas and CO2 emissions from fossil fuels to date and the future reductions needed to limit global warming.

Historical data (gray dots) for global greenhouse gases during 1900-1990 are linearly extrapolated from historical data of fossil CO2 emission levels for clarity.

The required reduction in CO2 emissions from fossil fuels to reduce emissions to 0 by 2050 is -12% annually from the 2021 value (white dots in 2020-2070).

Data source for future projected reductions in global greenhouse gases is based on data from the “Climate Action Tracker, May 2021 update” ( Data are updated regularly and therefore may vary.

Schubert CleanTech has a mission

Our mission revolves around innovative solutions in the field of energy, water and the environment, as we make our contribution to the energy transition in order to enable a livable future on this planet for our environment, our children and grandchildren.

Innovative solutions are key

To solve the challenges of the climate crisis and the energy transition, we have to do many things differently than we are used to. It is necessary to dare to do something new, to develop creative ideas and to implement them quickly. This is one of our strengths, and we are putting all our energy into it. Because one thing is clear: the political commitments and framework conditions do not yet make it possible to implement the necessary measures as quickly as would be necessary.

We focus on clean energy generation

The reduction of CO2 emissions is the key to overcome the climate crisis and the energy transition requires a massive expansion of renewable energy sources in the future.

We are the experts for equipment, integration, control and connection of hydropower plants, wind turbines, photovoltaic plants and biomass power plants and with our experience in dealing with EX zones we are the right partner to implement automation, control and medium voltage technology for hydrogen electrolysis and methanation.

Since 2000, renewable energy projects in the field of hydropower, wind power and photovoltaics, which have been implemented with SCHUBERT technology and know-how, have made a massive contribution to the reduction of CO2 emissions.

Thereby, the renewable energy generated with Schubert technology corresponds to an annual CO2 saving of more than 2 million tons CO2/year

The calculation is based on a CO2 equivalent of 401g CO2/kWh and the power plant capacity installed using Schubert technology based on the technology-dependent full load hours for hydropower, biomass power plants, wind power plants and photovoltaics (source: Federal Environment Agency UBA, Climate Change 13/2020 Report, page 9).

We focus on reliable energy distribution

Every year, more than 2,000 GWh of energy is distributed to our customers via the transformers and transformer stations we have supplied and installed over the past 10 years. In addition, there are more than 1,000 compact transformer stations in the distribution networks that we have equipped with Schubert technology. This total distributed energy volume corresponds to the average annual energy consumption of more than 2.5 million households.

Safe and reliable power distribution is the key to integrating volatile renewable energy sources.

We are the experts for turnkey installation, assembly and equipment of transformer stations, substations, transformers and converters up to 110 kV high voltage.

The calculation is based on the power and number of transformers and walk-in transformer stations installed and supplied by Schubert and compact transformer stations equipped with Schubert technology. Average household consumption is assumed to be 2,600kWh/year.

We focus on sustainable environmental and water technology

Our wastewater is cleaned and treated in the 1800 existing wastewater treatment plants in Austria in order to be reintroduced into the water cycle. In order to master the new challenges, such as the removal of microplastics, chemicals, nanoparticles and pathogens, the quality and technology of purification is constantly being researched and further developed.
For an economical and sustainable use of drinking water as a foodstuff, an optimal distribution system as well as a monitoring system of the quality, the consumed quantities and possible losses is required.
We are experts in new construction, modernization, maintenance and repair of water supply systems, wastewater treatment plants and pumping stations.
