Sustainable Polycarbonate: A Further Step in Sustainable Sun Lens Production

13 May 2025

At ZEISS Sunlens, sustainability is at the core of our innovation. We are proud to introduce our latest advancement: certified sustainable polycarbonate for snow goggles, developed using a mass balance bio-circular material approach and supported by the purchase of renewable electricity. This achievement reaffirms our commitment to reducing environmental impact while upholding the exceptional quality and performance our partners and customers have come to expect.

What is Mass Balance?

The mass balance approach is a highly effective method for transitioning to sustainable production processes. It ensures that bio-based raw materials are incorporated into the production process alongside conventional inputs, with their contribution carefully tracked and allocated.

This enables us to produce certified sustainable polycarbonate while leveraging existing infrastructure and reducing the environmental footprint, an essential step in our journey toward creating sustainable sun lenses.

Renewable Energy in the Production Process

A key component of this initiative is our commitment to utilizing electricity from renewable sources throughout the manufacturing process. By transitioning to renewable energy, we significantly lower the emissions, aligning our operations with global sustainability goals.

This approach not only supports environmental stewardship but also provides a reliable and scalable pathway for producing high-performance materials with a reduced carbon footprint.

Benefits of Sustainable Certified Polycarbonate

The certified sustainable polycarbonate developed by ZEISS Sunlens offers:

Reduction of fossil-based materials: bio-circular raw materials partially substitute the petrol-based material throughout the value chain.
Uncompromised Performance: the polycarbonate maintains the exceptional durability, optical clarity, and UV protection that ZEISS Sunlens is renowned for.
Market Differentiation: snow goggle brands partnering with ZEISS Sunlens can offer products that meet increasing consumer demand for sustainable sunglasses lenses.

A Vision for the Future

This innovation is more than just a material; it is a step towards reshaping the eyewear industry. By embracing sustainable polycarbonate and processes like mass balance, ZEISS Sunlens continues to set benchmarks in both technological innovation and environmental responsibility.

As the industry moves towards a more sustainable future, we remain committed to collaborating with our partners to create products that not only meet the highest standards of quality but also contribute to a healthier planet through the development of truly sustainable sun lenses.
