Sustain­ability

Sustainability means meeting the needs of the present without compromising the ability of future generations to meet their own.
We are actively committed to climate protection and align our economic success with our ecological and social goals.

We make the right decisions today for a better tomorrow — without compromising on quality or innovation.

United for Sustainable Solutions

“We are a partner of the sustainability initiative Blue Competence. Blue Competence is an initiative by the VDMA to promote sustainability in mechanical and plant engineering and to raise awareness of sustainable solutions within the industry.

Through our partnership, we commit to complying with the Twelve Principles for Sustainable Action.”

Our Commitment to Ecological Sustainability and Climate Protection

A key milestone on our path toward greater climate protection was the development of our first greenhouse gas inventory, prepared in accordance with the Greenhouse Gas Protocol standards. This comprehensive analysis covers emissions from Scope 1 through Scope 3.9 and was conducted for our Hannover site for the first time in 2022.

With this inventory, we have created a valuable tool to identify and systematically reduce the major emission sources along our value chain.

Starting in 2023, we expanded our focus to include our Shanghai site in the calculations — another important step toward making our climate strategy even more effective and holistic.

Reducing Our Emissions: Initial Success at the Hannover Site

We have already reached an important milestone: by reducing our share of externally sourced electricity and switching entirely to CO2-neutral power, our indirect emissions from purchased energy have been carbon-free since 2023.

* Greenhouse gas accounting is conducted in CO₂ equivalents (CO₂e), taking into account not only CO₂ but also other climate-damaging gases such as CH₄, N₂O, SF₆, and HFCs/PFCs, based on their global warming potential (GWP).

Measures for Sustainable Development

  • Installation of a Photovoltaic System on the Assembly Halls

    The installation of more than 2,300 photovoltaic modules on two hall rooftops, covering a total area of 4,000 square meters, has made a significant contribution to the energy transition in Hannover since 2022.
    “We are excited about the system, which will provide a strong boost to the energy transition in the state capital and enhance the energy security of our company,” says Bernd Pielsticker, Managing Director of TROESTER GmbH & Co. KG.

  • Switch to CO₂-Neutral Electricity

    Since switching to CO₂-neutral electricity in 2023, our indirect emissions from purchased energy have been carbon-free.

  • Calculation of Product Carbon Footprints

    By implementing a standardized process for calculating Product Carbon Footprints, we are creating transparency at the product level and enabling targeted measures to reduce emissions throughout the entire supply chain.

  • Energy-Efficient Refurbishment of the Administration Building

    In 2025, we will complete the energy-efficient refurbishment of our administration building. The goal is to optimize energy consumption and reduce CO₂ emissions, further strengthening our contribution to climate protection.

  • Expansion of the PV system

    By 2026, we will expand our photovoltaic system to produce even more renewable energy on site. This is an important step toward sustainably meeting our energy needs and reducing our dependence on fossil fuels.

  • Support for Sustainable Mobility

    We promote the use of sustainable transportation by offering bicycle leasing, installing EV charging stations, and providing financial support for employees who use public transportation. By 2027, we also plan to fully transition our company car fleet to electric vehicles — making the shift to more environmentally friendly mobility easier for everyone.

Our Climate Goals

We have set ourselves the goal of reducing 65% of Scope 1 and Scope 2 emissions at our Hannover site by the end of 2025, and additionally achieving net greenhouse gas neutrality in this area for the first time through offsetting.

In the long term, we plan to cut our Scope 1 and 2 emissions by 70% by 2030 compared to the base year 2022. Continuing net greenhouse gas neutrality in these scopes through annual offsetting remains a key component of our climate strategy.

For us, sustainability is not just a responsibility — it is an opportunity to shape the future responsibly and innovatively. Together, we are taking this path — for a livable future.

Our Social Responsibility Initiatives

For us, sustainability means more than just ecological commitment — it also includes taking responsibility for our employees. A healthy, safe, and family-friendly work environment is the foundation for long-term success and innovation. That’s why we implement targeted measures to promote the well-being, development, and job satisfaction of our workforce.

  • Reconciling Work and Family Life

    We understand that a healthy balance between work and personal life is essential for long-term satisfaction and performance. That’s why we offer flexible working hours and the option to work from home — helping our employees meet their individual life needs.

    Our work environment is shaped by a family-like atmosphere, where we foster an open corporate culture and provide strong support for our employees through all stages of life.

  • Health and Well-being in the Workplace

    The well-being of our employees is close to our hearts. Through a comprehensive company health management program, we actively promote both physical and mental health. An in-house physiotherapist is available for targeted treatments, while our partnership with Hansefit gives all employees access to a wide range of sports and fitness options.

    Our company restaurant also provides daily access to high-quality meals. In addition, our annual participation in the corporate run — which centers on team spirit and athletic ambition — encourages everyone to get moving together.

  • Sustainable Mobility and Climate-Friendly Commuting

    As a company with a clear climate strategy, we actively promote sustainable mobility solutions for our employees. These include attractive offers such as bicycle leasing, financial subsidies for the use of public transportation, and company-owned EV charging stations — all designed to make the switch to low-emission transport easier.

    By creating incentives for eco-friendly commuting, we are working together to help reduce CO₂ emissions.

  • Security and Future Opportunities

    A secure workplace is a matter of course for us. We implement comprehensive occupational safety measures to minimize risks and ensure a safe working environment.

    In addition, we actively invest in the future — offering high-quality apprenticeships and dual study programs that give young talents the best possible start to their careers.

    Because sustainable business success also means passing on knowledge and opportunities to the next generation.

Responsible Corporate Governance

As part of our commitment to responsible corporate governance, our Code of Conduct serves as an important foundation for respectful and ethical interaction among employees, as well as with our customers, business partners, and the wider public. It outlines key principles and values that guide our daily actions.

Due Diligence in the Supply Chain

In line with our supply chain due diligence, we conduct an annual review of our active suppliers using a system-based approach. This begins with a general risk analysis that considers both geographic and industry-specific factors. If risks are identified, a more detailed risk assessment follows. This process enables us to better evaluate the risk profile of our suppliers while also enhancing transparency throughout the supply chain.
