Lighter Impact

Our products enable a more connected society, allowing for information to flow at faster rates and people to interact from around the world. More areas of the world are gaining access to the internet, which is unlocking vast resources and reducing the burden of travel, as education and employment are now more accessible from home. Our laser technology unlocks more precise and powerful technologies that further drive down the scale and increase the power of data and communication networks. These factors all further Lumentum’s role in contributing to a more efficient world that operates with a lighter footprint.

Net Zero by 2030

Lumentum Headquarters

The environmental impact of organizations and their responsibility to manage their contributions to climate change have become clear priorities for our stakeholders. At Lumentum, we recognize the climate change we are facing and believe we have a responsibility to act. In FY21, Lumentum committed to achieving net-zero Scope 1 and 2 GHG emissions targets by 2030. In FY22, we decided to broaden our impact and committed to setting near- and long-term company-wide emission reduction targets in line with the science-based standard for net-zero emissions from SBTi.

In FY21 our journey to net zero began, procuring 100% renewable electricity to power our headquarters in San Jose, California, USA, a new R&D facility in Milan, Italy, and a manufacturing facility in Škofljica, Slovenia. In FY22, we added Caswell and Paignton, UK; Ottawa, Canada; and Zurich, Switzerland to the lists of sites running on 100% renewable.

As we grasp the challenges and opportunities that lie ahead, we are committed to rising to the occasion.


Impact on Climate

Impact on Climate

Lumentum recognizes the global effort needed to mitigate the worst impacts of climate change. We realize the risk that climate change has on our business in the short, medium, and long term and have begun to incorporate climate change mitigation into our business objectives and strategy. 

To monitor and manage our contributions to climate change, we have responded to CDP’s Climate Change Questionnaire since 2017 (see our 2022 CDP Climate Change Response). CDP’s alignment to the recommendations from the Task Force for Climate-related Financial Disclosures (TCFD) help us refine our governance structure and consider the risks and opportunities associated with climate change. 

We aim to strengthen our practices and disclose our progress, and we are further developing our greenhouse gas management program. Our current inventory includes accounting for scope 1 and scope 2 emissions associated with our facilities’ energy consumption and the scope 3 emissions from our contract manufacturers, business travel, and other energy-related activities. We encourage our suppliers to participate in CDP and leverage tools, such as Supply Risk Solutions, to monitor our supply chain’s climate-related risks. We undergo an annual independent assurance of our greenhouse gas inventory (see our Assurance Statement for 2022 CDP Climate Change Response).


Water and Effluents


Lumentum withdraws but does not consume large quantities of water in our operations as it is an important resource for cooling, cleaning and personal hygienic use at our production facilities. In addition, several of our manufacturing facilities are in areas that experience water stress, and over half of our facilities carry out activities that could be subject to disruption due to a lack of water supply. 

Integrated with our Environmental Management System (EMS), we have formal water quality management programs in place covering aspects from wastewater treatment to storm water runoff and drainage. In addition, we evaluate our water impacts through our annual submission to CDP’s Water Security Questionnaire, which we’ve responded to since 2017 (see our 2022 CDP Water Security Response).




We understand the impacts that waste generation can have on surrounding communities, particularly if not treated properly. We believe organizations have a responsibility to reduce their contributions to waste streams wherever possible.

Our global sites produce both hazardous and non-hazardous waste through our production processes and from general operations. The generation of hazardous waste is inherent in our industry, but at Lumentum, we ensure strict compliance with all local laws as they relate to the generation, treatment and transportation of hazardous waste. In FY22, we set a goal to increase the diversion of our non-hazardous waste to 90% by FY27.

Over 60% of our manufacturing sites and all of our contract manufacturers' facilities are ISO 14001 certified.
