Responsible action has always been linked to our long-term success. As a company of the Carl Zeiss Foundation, we have been living these values for over 100 years. We work with our teams, worldwide, to preserve resources while providing eye care solutions to help people see better.
To fulfill our responsibility, we focus on three major areas:
With our technologies, products and solutions, we have been influencing the lives of people for many years. And we are fully aligned with our sole owner, the Carl Zeiss Foundation, in understanding that sustainability is essential for the future of humankind, of our customers, our company and our employees.Sven Hermann, Head of ZEISS Consumer Markets
The climate crisis and its impact on our planet is very real. ZEISS wants to be part of the solution.Dr. Nicole Ziegler, Head of Sustainability ZEISS
As part of our sustainability strategy, we aim to achieve carbon neutrality in our own operations by 2025. In combination with the goal of switching to green power at our main sites worldwide by 2022, we are contributing to the Paris Agreement of limiting global warming below 2°C.
green power supply in our main sites worldwide
CO2 neutrality on all our own global activities
We ensure that less water, energy and plastic goes into the production of our eyeglasses and that less CO2 is emitted across the entire value chain – from the manufacture of semi-finished lenses all the way to final delivery.
Within over 250 individual initiatives we strive to better fulfill our responsibility each and every day. We are working hard to achieve sustainable business practices across the entire process.
With a save enough water to meet the drinking water needs of 180,000 people for one year.
We save enough energy to provide 3.100 households with electricity for one year.
Our yearly waste reduction is equal to the weight of 2.5 million plastic bags.
Our new eyeglass packaging saves 68 tonnes of paper each year.
With a mixture of hydro- and biomass power, the site has been meeting its energy needs through 100 percent renewable sources. The amount of the booked renewable electricity would satisfy the electricity needs of about 1.500 Italian families and contribute to avoid more 1.500 tons of carbon dioxide emissions annually.
To counteract water scarcity in specific production regions, the eyeglass lenses plant reuses wastewater from operations processes for uses with lower water quality requirements. This results in an annual avoided water consumption of about 100 m3, the equivalent necessary for satisfying the yearly water drinking needs of 100 people.
The Bangalore factory collects rainwater on a surface of 1.200 m2 on the factory roof and uses it for lenses production. This way, the avoided consumption of the municipal drinking water, about 690.000 liters a year, is available for the citizens in an area facing water shortage during the drought season.
Renewal of a compressed air system always leads to higher energy efficiencies, but in this case has also triggered the idea in our engineers in Guangzhou to recover the exhaust air generated by reusing it in the warming of our tinting baths: about 90 MWh consumption less, the equivalent of a domestic energy consumption of 30 Chinese families.
The plant in Hebron has partnered up with a local business from the automotive industry. The partnership allows reusing the spent alcohol from the lenses production process as a raw material for the manufacturing of new alcohol-based products. Every year about 150 kg of potentially harmful volatile organic compounds can be therefore recycled.
In order to make lens production as sustainable as possible, we continuously scrutinize and improve our production processes. We are developing methods that allow us to manufacture lenses with ever decreasing material input and replace outdated production equipment with energy-efficient devices.
We want to move away from the tradition of automation for its own sake, towards a relentless pursuit of optimal parameters that can result in the lowest energy consumption and the lowest volume of waste production.
Not only the volume of materials used is crucial for sustainable development, but also the raw materials themselves. Using a significant number of bio-based materials, we have developed more eco-friendly manufactured sunglasses lenses, offering customers a sustainable choice.
We have managed to significantly reduce the use of resources in the manufacturing of eyeglass lenses of semifinished lenses.Jesper Wiegandt, Chief Marketing Officer ZEISS Vision Care
Our goal is to use less water, less energy and reduce the production of waste for all our production processes.Emanuele Novelli, Sustainability Manager ZEISS Vision Care
The need for affordable yet good quality spectacles in rural and unserved regions of India is massive. The Aloka Vision Programme, initiated and supported by ZEISS, aims to change the landscape of vision care in such areas through entrepreneurial networking, technology, innovation, quality spectacles and raising awareness of the benefits of clear vision.
As families in rural China are often too poor to afford lunches, the free lunch fund offers school meals for children. ZEISS joined the project in 2014 and has since then raised around 820.000 free meals for children. Furthermore ZEISS, together with its partners, brings eye and vision care to the partner schools by providing professional eye checks and donating free lenses.
To prevent blindness and visual impairment caused by uncorrected vision loss and address the debilitating visual impairment problem, Optometry Giving Sight was founded in 2003. With a donation of more than $110.000 ZEISS Vision Care Canada, in collaboration with WestGroupe, has helped fund critical local developments such as an optometry school in Vietnam and the equipment for an optometry programme in Malawi.
