Environmental and climate protection by conviction

Protecting our environment

is a high priority for us, and we see it as our corporate responsibility to grow sustainably in harmony with the environment and society. As a technology company, Jenoptik is not in an energy-intensive sector, and produces a very small amount of emissions.

As a manufacturing company, our focus is on efficient resource management to reduce energy consumption and the ensuing greenhouse gas emissions as much as we can, using commodities and materials carefully and safely and to avoid hazardous waste as far as possible. From the very start of the development process, we paid attention to environmental aspects and the economical use of resources. Through regulated recycling and disposal, we can minimize the impact on people, the environment and nature.

The EHS division is responsible for managing and controlling environment, health and safety matters. It defines Group-wide targets and framework conditions and integrates management systems into business processes. Operational implementation takes place in the divisions. Continuous review, regular internal audits and external certifications ensure that systems meet standards. Depending on their environmental relevance, selected Jenoptik companies are certified compliant with the environmental management standard ISO 14001.


Climate change is one of our biggest challenges. Climate protection is also of central importance to us as Jenoptik. As an “enabler”, our products make an indirect contribution to greater climate protection and resource conservation.

Energy and emissions

As a technology company, Jenoptik is not in an energy-intensive sector, and produces a very low level of emissions within the site. Much of our emissions are attributable to purchased and externally purchased energy such as district heating, electricity or gas.


As a technology company, Jenoptik uses water only as a coolant, a process medium and for sanitary purposes – no large quantities of water are required for production processes. However, as part of our water management at all locations, we ensure that water consumption is kept as low as possible.

Our aim is to avoid, as far as possible, waste from production, to recycle it and, if this is not possible, to dispose of it properly in order to keep the negative impact on the environment to a minimum. Waste is generally recycled by certified specialist waste disposal companies. Permanently implemented measures include continuous waste separation and training of employees in waste prevention.

Product responsibility

For Jenoptik, product responsibility means that our products and solutions meet the highest quality standards and are safe for people and the environment when used properly. We ensure that resources are used responsibly throughout the product live cycle. In doing so, we focus on the three fields of action: material use and energy efficiency, design and construction, and avoidance of pollutants and waste.

      Environmental protection

      Protecting the environment is a high priority for us, and we see it as our corporate responsibility to grow sustainably in harmony with the environment and society and to use resources and energy efficiently. Our products enable our customers to act in a resource-saving, efficient and sustainable manner.

      Environmental management is a solid part of our corporate conduct. Our suppliers and contractors are also required to comply with the applicable regulations in order to minimize environmental risks. As a manufacturing company, our focus is on

      • efficient resource management to reduce energy consumption and related greenhouse gas emissions as much as we can;
      • careful and safe use of materials;
      • avoiding waste as much as possible;
      • ensuring environmentally friendly design and economical use of resources from the development process;
      • and minimizing the impact on people, the environment and nature through regulated recycling and disposal.

      For all new constructions, extensions and modernization work of production, we comply with statutory nature and environmental protection standards and sometimes exceed them.

      Competition for greater sustainability


      Jenoptik employees are committed to more sustainability in the company and more environmental protection not only in their direct working environment, but often through joint campaigns at their sites.

      The Group-wide sustainability contest, which was launched in 2020, rewards this commitment for projects implemented in the following categories:

      • Waste / recycling / circularity
      • Careful use of resources
      • Energy or CO2 savings
      • Biodiversity

      An internal jury evaluates all proposed projects after the submission deadline each year and awards prizes to the best entries.

      Successfully implemented sustainability projects


      In line with recycling management, Calcium fluoride lenses that were evaluated as defective scrap parts can now be converted to other raw parts internally to manufacture other lenses. This procedure reduces waste, conserves resources and avoids scrapping high-value materials.

      In addition, ...

      • Saving solvents in the manufacturing process of semiconductor lasers at our Berlin Adlershof site.
      • Transfer of more plastic materials to the recycling process at the Triptis site.

      Zero carbon power

      With iTASCAR, our developers in the UK succeeded in creating a sustainable and environmentally friendly solution for measuring average speed. Previously, electricity grids or diesel generators were required for connection. Now, only renewable and carbon-free energy from wind, solar and hydrogen is used for this purpose.

      Resource conservation

      In the production of "honeycomb filters" in flash lamps, waste is reduced and resources are saved thanks to an efficient solution by printing an intermediate frame using a 3D printer to replace the silicone layer. Thanks to this production of partial components, the filters now no longer have to be completely replaced and disposed of. Instead, filters, frames and intermediate frames can be replaced individually.

      Employee engagement

      In cooperation with the "Coastal Environmental Foundation", Jenoptik employees in Japan organized a beach cleanup and collected trash to reduce the local environmental impact. Besides, Jenoptik Japan became a member of the foundation and plans to repeat the beach cleaning event annually to make the contribution to environmental protection more permanent.

      In addition, ...

      • Tree planting campaign in Jena, Germany for more greenery in and around the city.
      • Jenoptik takes over bee sponsorship with the Jena Beekeepers' Association.

      Resource conservation

      With TraffiPole, our developers succeeded in creating an environmentally friendly and sustainable traffic monitoring solution that can also be operated autonomously with batteries or solar panels, thanks to a housing made of fully recyclable materials, reduced power consumption and the elimination of cooling.

      In addition, ...

      • In Monheim, Germany, the life cycle of furniture and equipment was extended and indoor emissions were reduced by cutting down on fax machines and printers.
      • In Jena, irrigation bags were purchased for 100 trees to ensure water and nutrient supply to the trees close to the Jenoptik premises during dry periods in midsummer. Both water evaporation and water consumption are greatly reduced as a result.


      With a great deal of commitment, Jenoptik employees planted 1,000 trees in the Jena forest and made a contribution together to climate protection and more greenery in Jena.

      A green roof was installed on a newly constructed building in Villingen-Schwenningen to promote biodiversity. The roof uses rainwater for the plants on the roof, provides improved thermal protection in summer, and has less heat storage in the evening hours.

      Employee engagement

      Based on idea from an employee, a mobile organic farm store supplies employees with regional and seasonal products every Friday on the front yard of the production buildings in Jena.

      Land reclamation and beautification: Jenoptik employees in Jupiter, Florida cleared an old scrap yard on the production site and then reclaimed the area as an outdoor fitness area and work-out space. This project helped restore nature, decrease industrial footprint and create long-term health benefits.

      More biodiversity

      The winner in 2020 was our UK team at the Camberley site with a project in the Biodiversity category.

      By redesigning an area close to the company, targeted planting of shrubs and wildflowers and the installation of insect hotels transformed the unused grassland into a kind of recreation area for our employees, which is used for walks and yoga during breaks and provides a home for numerous insects.



      Reuse of packaging material in sensors division: foam corners and cooling packs are fed into the recycling circuit in Dresden and used for new packaging. This reduces foam waste and hazardous waste and protects our environment. Old boxes are also recycled for consignments and even coffee grounds are used as a humus in the garden.

      In addition,

      • solvent use is reduced in the production process of semiconductor lasers in Berlin Adlershof
      • The Triptis site is transferring more plastic materials to the recycling process
      Energy savings

      Energy savings

      LED lighting is generally installed during modernizations which creates a better working environment and saves valuable resources through a longer service life. The introduction of a compressed air control system has optimized the power consumption of compressors. The increased machine service life also saves resources and reduces repair costs. The introduction and establishment of peak load management in the transformer sector has led to savings in electricity network utilization. A brief shutdown of secondary processes (e.g., room cooling) prevents power peaks that put strain on the grid. Non-essential systems (e.g., air conditioning systems, canteen ventilation systems, refrigeration systems, etc.) are adapted to work processes for the Covid pandemic and weekends or are completely switched off to save electricity.

      Environmentally friendly vehicles

      "Go Green"

      Transformation of the vehicle fleet to hybrid vehicles. Reduction of CO2 emissions and pollution contribute to greater environmental protection. Fuel savings and competitive vehicle prices with lower fuel costs increase efficiency.

      In addition,

      • drinking water dispensers and reusable drinking bottles are replacing the complex water ordering process at various locations, which saves time and reduces transport costs and emissions.

      Health and Safety

      Safety management and health protection are important fundamentals of corporate responsibility in the Jenoptik Group and important measures when it comes to the basic needs of our employees and job satisfaction. They are firmly anchored in the operating process in order to minimize risks from the working environment that can endanger employees. The prevention of accidents in everyday work, while production facilities are operating, and on work and transport routes is our top priority.

      The EHS (Environment, Health & Safety) division is responsible for managing and monitoring all occupational, health and safety matters. It is the responsibility of the Chief Financial Officer and is available to all companies in an advisory capacity. It defines responsibilities, objectives and framework conditions, such as the “Environmental Health, Safety and Environment Group Policy” published in 2020. Jenoptik companies are responsible for implementing statutory provisions in all matters of occupational health and safety.

      Around 10 per cent of employees at all German locations are trained as first aiders. In the interests of their health and performance, our employees undergo regular occupational medical examinations. In 2021, the number of reportable workplace and commuting accidents in Germany amounted to 9.1 per 1,000 employees (previous year: 11.4), for the Group as a whole, the ratio was 9.5 – significantly below the average of 19.5 in 2020 for the other members of the Employers’ Liability Insurance Association for Energy, Textile, Electrical and Media Products.

      Pandemic management

      With the help of a pandemic and hygiene plan at all locations, the spread of infection was prevented, while the work capability was maintained in all areas. Rapid and regular exchanges between all the coronavirus task forces, keeping employees informed, but in particular the rapid introduction, implementation and consistent enforcement of hygiene measures, the offer of vaccination and opportunities for home working contributed significantly to the success.

      Occupational health management

      Operational health at Jenoptik is managed centrally in the Corporate Center in Germany, supported by local “Health Steering Committees” for the implementation of on-site measures. These include the “Move It!” initiation project, a digital movement offer for all employees, a “healthy leadership” training offer for our managers and continuous improvement of the process for company integration management.
