Lenovo Sustainability

Water, Waste, & Other Emissions

Our Approach

Among our key environmental management objectives, we aim to use less of the planet’s scarce resources by minimizing water withdrawal and waste generation, while maximizing the reuse and recycling of materials.

Our focus is on:

Improving water efficiency, reducing waste generation, and increasing reuse and recycling
Increasing our understanding of water- and waste-related risks
Being transparent about our water and waste performance levels


All water used at Lenovo is related to human consumption and sanitation. We do not have any wet processes in our manufacturing or research and development operations, and therefore do not set any internal global water reduction targets.

However, some of our facilities have established water-related goals. We also set operational control water targets for global water withdrawal and global wastewater generation. Lenovo has its water withdrawal and wastewater discharge data third-party verified.

Waste Water Withdrawal

Note: Water data includes manufacturing, research and development sites and some large office locations. Lenovo's fiscal year is from April 1 through March 31. Beginning in FY 2015/16, System x and Motorola Mobility data are included in water data.

Water we draw is mainly from municipal sources and is for human consumption and use only. We therefore have minimal impact on local water resources and minimal opportunities to reuse water.

However, several of our sites have installed water efficient fixtures in restrooms, purchased water efficiency equipment for cafeterias, minimized the need for irrigation by planting indigenous plants, and collected rain water to reuse for flushing toilets and landscaping.

In 2017, Lenovo responded for the first time to a water questionnaire from the CDP. The CDP is a non-governmental organization that operates a voluntary public reporting system to help corporations, private businesses and governmental entities better manage their environmental impacts.

Lenovo was rated as Management Level with a score of B and our Supply Chain Water score was also a B. For more information on this, including our water report and water risk mapping, please visit the CDP website.

Product Water Footprint

Lenovo recognizes the importance of water withdrawal in our own operations and our supply chain. In addition to the metrics we collect on water withdrawal in Lenovo’s operations described above, we conducted a pilot product water footprint evaluation for a Lenovo desktop product.

The pilot evaluation done on a ThinkCentre X1 showed that the most significant impacts to water consumption during the lifecycle were related to components of the mainboard production, the display production, the assembly phase, and the use phase of the product.

Next steps will be to look at how we can innovate and improve on the mainboard and display manufacturing and assembly processes, as well as making improvements to energy management during the use phase, in order to have the biggest impact on reducing the product water footprint.

For details on the assessment, please see the full Product Water Footprint Report Declaration.


Lenovo’s waste inventory is shown below. Our nonhazardous and hazardous waste data is third-party verified.

Lenovo’s Waste Inventory (m³)



  • Waste data includes site waste from manufacturing, research, and development sites, including some large office locations.
  • Our fiscal year is from April 1 through March 31. Since, FY 2015/16, System x and Motorola Mobility data are included in our waste data.

Nonhazardous waste generation has increased slightly in the last fiscal year. In FY 2017/18 Lenovo's nonhazardous solid waste recycling rate was 91.4%. Our global waste intensity as total nonhazardous waste generated per unit produced during the fiscal year increased, which can be attributed to a year-to-year total production decrease.

Other Emissions

Lenovo prohibits the use of ozone-depleting substances in our products and manufacturing processes except in HVAC and fire-suppression equipment as permitted by law. Ozone-depleting substances used in HVAC and fire-suppression equipment are managed in accordance with local regulations, and intentional releases are prohibited.

Lenovo does not have significant direct air emissions such as NOx and SOx. In addition, Lenovo has no wet chemical or industrial processes that use volatile organic compounds (VOC) and thus has no point sources of VOC. Household and cleaning products that contain small quantities of VOC are used at some of our facilities, but associated fugitive emissions are minimal and are not quantified.
