Looking toward the future.
Developing and manufacturing premium eyewear also means addressing the associated impact.
Thinking beyond Materials. Using Products longer.
For us, product design, material selection, and product service life go hand in hand. That’s why we consider resource use across the entire product life cycle: We are gradually incorporating bio-circular materials, working to use materials efficiently, and—through quality, repair options, and replacement parts—creating the conditions that allow products to be used for as long as possible.
Water treatment.
Targeted management of environmental impacts.
Water is needed for many steps in our production process. That is why we treat process water, return some of it to the production process, and are working to further reduce our fresh water consumption. We also manage other environmental impacts of our production processes through specific measures—from waste water and exhaust air to the handling of materials and waste.

Less CO2e in material production
The actual CO2e value is calculated on a batch-by-batch basis and may vary slightly.
85 %
of each pair of glasses can be repaired
Calculated based on the components of a pair of glasses that are available as replacement parts.
50 %
less fresh water per pair of glasses
Calculated based on the ratio of fresh water to reused, treated production water per pair of glasses.
All values shown are rounded. The basis for each calculation is explained directly next to the value.
Fewer emissions. More transparency.
For us, climate protection begins with knowledge. That is why we track our greenhouse gas emissions in accordance with internationally recognized standards, consistently reduce them through technical and organizational measures, and offset only unavoidable residual emissions. In this way, we lay the foundation for transparent and effective climate protection measures.
Shaping the work environment. Involving the supply chain.
Effective collaboration requires a safe and respectful work environment. That is why we promote health and workplace safety and create opportunities for dialogue and active participation. We also involve our suppliers: Our Code of Conduct sets forth requirements for integrity as well as environmental and social standards. When onboarding new suppliers, we verify their compliance and, depending on the risk, supplement our assessment with document reviews and on-site audits.

“For us, sustainability work begins with systematically examining the impact of our business activities on the environment and people. From this, we identify specific measures and use data and key performance indicators to track developments and identify further areas for action.”
We don't have to. We want to. Our sustainability report.
Even without any legal obligation, we report on our sustainability performance. This is the third time we have done so voluntarily and the first time in accordance with the European Sustainability Reporting Standards (ESRS).
We draw on 30 years of experience: We have been reporting regularly on our environmental performance under EMAS since 1996. With our current sustainability report, we are broadening this perspective and further developing our reporting.
Code of Conduct
Clear Principles for How We Work.
As an independent family-owned company, clear values are an integral part of our corporate culture. Our Code of Conduct translates these principles into concrete rules for our day-to-day work and sets a binding framework for everyone across the Silhouette Group – from the Executive Board and managers to employees at our production sites and subsidiaries.
It provides guidance for respectful and ethical conduct and covers, among other topics, respect for human rights and equal opportunity, fair competition and anti-corruption, data protection and the protection of confidential information, as well as environmental protection and occupational health and safety.

What inspires us
We are completely eliminating fossil natural gas at our Linz location. By electrifying key production steps, our eyewear production will operate 100% without fossil natural gas starting in April 2026. This will save us several hundred megawatt-hours of natural gas and more than 100 tons of CO₂e annually.

On July 7, 2025, our photovoltaic system at our Linz site reached a significant milestone: Since the first system was commissioned in 2020, our on-site solar power generation has resulted in the calculated avoidance of more than 1,000 metric tons of CO₂e.
