Building systems

When selecting new locations for our business operations, a great deal of consideration is given to their environmental impact, particularly at Ciena’s largest offices. We target builders and site developers who embrace green building practices, as well as locations convenient to public transportation hubs. Energy management is an important factor in our overall facilities strategy. Monitoring of lighting, HVAC, water, and energy consumption patterns are part of our facilities management plan and adjusted to reduce environmental impact.

Workplace practices

We encourage our employees to consider commuter options such as public transportation, carpools and vanpools, and ridesharing programs. In most cases, Ciena locations are close to public transportation. Many Ciena offices provide bicycle racks and reserved parking spots for car and vanpool vehicles as well as electric/hybrid vehicles. Our recycling program ranges from paper sorting and recycling bins to “single-stream” recycling and waste management, including removing refuse and recycling from the site for sorting and disposal. In addition, Ciena provides employees with updates on energy conservation methods they can put into action both at the workplace and at home.

Business processes

Ciena has taken steps to introduce alternatives to traditional work processes and practices that reduce the impact on the environment. Some of those changes include reduction of business travel through the introduction of virtual meeting tools (videoconferencing, etc.) and telework arrangements. As a global company, we have found ways to schedule shift operations in several different locations around the world, handing off project work and customer coverage at the end of the local business day. This approach enables us to offer 24-hour availability without the energy consumption required to operate multiple sites around the clock.


Ciena’s team of specialists works closely together with customers to design and evolve networks in a manner that reduces overall power consumption while supporting the industry’s growing technology requirements. Power and footprint reduction are key considerations when developing products, and our expertise in multi-layer switching, mesh capacity sharing, and high-line-rate transmission support the design of next-generation and modernized networks that reduce the impact on the environment. Ciena recognizes that customers may want to upgrade their networks and Ciena has a method to assist in recycling that material to reduce environmental impacts. Please contact your program manager or sales representative for further information. Additional information on the EU/EFTA WEEE Take back and Recycling Program can be found here.

Climate change

Ciena continues to monitor developments in relation to climate change and the potential impact on its operations. This is part of a holistic approach to business continuity and business strategic planning. Ciena operates a third-party certified Business Continuity Management System which, through its multi-disciplinary functional representation, identifies business continuity risks (including climate change risks). This process also reviews business impact and enables implementation of mitigation plans to minimize impact to business operations, e.g. disruption from adverse weather conditions. This strategy is reviewed by senior management along with the business strategic planning which spans a longer time horizon. The Business Continuity Program includes reviews, exercises and recovery plans regarding emergency processes at the asset level.  Examples of both programs include natural hazards and their effect on operational sites including offices, labs, test and production assets, key personnel and supply chain assets.

Prioritization is determined by operational significance and investment requirements.  Additionally, following the annual functional area reviews with the Business Continuity Team, the affected parties review the risks and opportunities. The risks and opportunities identified are then prioritized in the context of their business impact. Operational response is planned in line with that identified risk and priority.

Data is collected from our various risk management tools and processes (third party supplied databank and internally created supplier tool that reviews geographical supplier risks, Business Continuity Program, direct supplier engagement, Corporate Security monitoring of global hazards, Environmental, Health and Safety risk assessment process). Reviews of the outputs of these tools and processes allow Ciena to strategize, implement improvements to existing processes, identify target opportunities and identify the need for additional mitigation. Senior management is briefed on a regular basis regarding these risks and outputs/process decisions and provides feedback and overall approval of strategy.  The strategy has been influenced by extreme weather conditions and natural hazards, regulatory changes, natural resource depletion. All of these aspects have led to the need for adapting our business to reflect climate change concerns. This includes setting energy reduction targets for site energy consumption as well as potential targets for product energy consumption.
