Sustainability at ZEISS

Projects and initiatives for a resource-efficient and innovative future

As a foundation-owned company, ZEISS is committed to benefiting society through technological innovation. Sustainability and business success are therefore inextricably linked. We work continuously to embed sustainable value creation as an integral part of our business activities.

ZEISS’ commitment to sustainability is firmly anchored in its strategy. Our Sustainability Strategy 2030 further advances ZEISS’ commitment to sustainable concepts. ZEISS contributes to the United Nations’ global Sustainable Development Goals and focuses on seven of the 17 goals.

Under the guiding principle of “Act on Sustainability to Create Value,” the aim is to integrate sustainable approaches into decisions and processes even more strongly in the future. Our Sustainability Strategy 20230 further advances ZEISS' commitment to sustainable concepts. To this end, ZEISS has grouped the four key focus areas under the umbrella of ESG (Environment, Social, Governance): climate protection, circular economy, people & society, and corporate governance.

17 Sustainable Development Goals by the United Nations

Sustainability

A social responsibility

Sustainability is more than climate action. This is how the United Nations sees it in its Sustainable Development Goals, which point to social change. ZEISS is also committed to these goals.

Climate action in practice at ZEISS

ZEISS aims to drive the decarbonization of the company and its customers.The three key levers for this are a climate pathway program aligned with the Science Based Targets initiative (SBTi), use of renewable energy at ZEISS locations, and reliable product carbon footprint data.

This enables ZEISS to support customers in making informed decisions to reduce product-specific emissions throughout their value chains.

  • SDG 13 – Climate action

Realizing a circular economy

ZEISS aims to create value, strengthen resilience, and reduce environmental impacts by using resources for as long as possible and closing material loops. For ZEISS, the circular economy is a systematic approach that encompasses the entire product life cycle. The three key levers for this are eco-design, resource efficiency, and circular services and maintenance.

  • SDG 9 – Industry, innovation, and infrastructure
  • SDG 12 – Responsible consumption and production

Corporate governance

As part of its corporate governance, ZEISS translates social values into clear structures, processes, and behaviors. This is achieved by fostering a culture of compliance and promoting transparency. The ZEISS Compliance Management System and an effective operating model are designed to help employees act responsibly and to bolster the trust that partners and other stakeholders have in ZEISS as a reliable, compliant business partner.

Sustainability is a key driver for innovations that create greater added value for society and thus help ZEISS to set itself apart from our competitors.
