Combating Climate Change: Products

Energy-Efficient Products

Lenovo’s historical and continued focus on product and operations energy efficiency provides a strong product differentiator in a market and regulatory environment that increasingly values these attributes. With a development process that places a premium on energy efficiency, an already outstanding offering of energy-efficient IT products and internal processes in place to drive continued improvements in operational efficiency, Lenovo is well positioned to benefit from an increasing demand for energy-efficient products with smaller carbon footprints.

Energy efficiency is a targeted attribute of the Lenovo product development process. Improvements in product energy efficiency are consistently part of our key environmental objectives and targets.

Lenovo PCs come with built-in energy-efficient tools and eco-friendly features that include:

  • For recent Windows systems, the "Lenovo Settings" app — provides power management features for the user (i.e., Connected Standby).
  • Adaptive Thermal Management — adjusts system power and fan speeds based on ambient levels.
  • Active Directory and LANDesk® — supports remote deployment of power schemes and global settings to allow administrators the ability to control and enforce ThinkPad® energy savings company-wide.
  • Lenovo EasyResume — gives quick recovery from computer lid close, balancing low power state by suppressing CPU usage at lid close.
  • Intelligent Cooling — balances thermal performance to adjust settings to provide a cooler surface for comfort while optimizing product energy performance.

Lenovo servers come with built-in energy-efficiency tools and eco-friendly features that include:

  • For the Think server management model, the "New Customer WebUI" app — provides power management features for the user.
  • For the Think server management model — supports remote deployment of power schemes and global settings to allow administrators the ability to control and enforce ThinkPad® energy savings company-wide.
  • For other operating systems, Power Manager™ — helps optimize energy used by a running machine and saves up to 30 percent on energy consumption and 50% percent performance.
  • Lenovo ASHRAE Management — adjusts processor and fan speeds based on ambient levels.
  • Rack Planner — helps users better plan for rack efficiency by increasing rack density and calculating power consumption based on specific configurations.
  • Smart Grid — helps users monitor and manage power consumption and temperature of ThinkServer with Intel Node Manager. It can save power, increase rack density, and avoid Data Center hotspots.
  • PSU smart-on — when system detects that the power loading is low in redundant PSU configuration, system can transfer the loading from 2 PSU to 1 PSU to get higher power efficiency and save power.
  • Diagnostics — capabilities and Easy OS installation (LEPT) embedded.
  • 80 PLUS TitaniumTM server power supplies or PSUs — by improving the efficiency of the server PSUs, energy efficiency improvements can be cascaded up through the data center for both power and cooling.
  • Liquid cooling solutions — can reduce the facility demands for data center chillers resulting in facility infrastructure savings.
  • Lenovo Efficiency Mode™ (LEM) — works in cooperation with the operating system to fine tune the operating efficiency of the server. LEM can boost performance per watt efficiency by up to 11% compared to a server that is not using LEM.
  • Unused devices embedded in System x servers are either powered down or placed into very low power state automatically during boot time and/or dynamically at run time — examples of devices where power is intelligently managed include:
    • CPU cores
    • Memory channels and DIMMs
    • PCI Express ports
    • QPI links
    • SATA and SAS storage controllers
    • Network controllers
    • Serial ports
    • USB controllers
    • Voltage regulatory devices (VRDs)

Lenovo offers a full complement of ENERGY STAR® qualified notebooks, desktops, workstations, monitors and servers.

Measuring Product Efficiency

Lenovo recognizes that the existence of a universally accepted method for establishing product carbon footprint (PCF) will promote targeted product energy reduction actions and allow for product differentiation. To this end, Lenovo is engaged in the development of PCF protocols and tools with external partners.

Lenovo is engaged with other members of the information and communication technology (ICT) industry and academia in the development of a tool to simplify and expedite determination of the PCF for ICT products through the Product Attribute Impact Algorithm (PAIA) project. It is hoped that this work will move the industry towards a standard method for establishing PCF. Lenovo’s product development groups are currently in the process of using PAIA notebook, desktop, monitor, all-in-one, tablet and thin-client PCF calculation tools.

Internally Lenovo continues to work on quantifying the lifetime impact of its products. The carbon footprint of Lenovo's products will help identify lifecycle areas where GHG emissions can be effectively reduced. An internal product carbon footprint calculation guidance has been developed to support quantifying the product life cycle GHG emissions of Lenovo's products. This document is written in accordance with ISO 14040 & 44 Environmental management – Life cycle assessment and consistent with Publicly Available Specification 2050, and Greenhouse Gas Protocol's Product Accounting & Reporting Standard. Each business unit must follow this guide in assessing the life cycle emissions of its products.

Lenovo has been actively involved in the following carbon footprint projects:

  • Product Carbon Footprint China Standard,
  • China ICT Product Life-Cycle Assessment Data Service Platform,
  • IEC Technical Report GHG Quantification Methodology for Computers,
  • China ICT Supporting Low Carbon Economy,
  • EICC Product Carbon Footprint Data Allocation Algorithm Development.

Due to its strong local presence in China, Lenovo is engaged in advocacy efforts in China energy and carbon standards and policies in the PC+ field, and is active in the following energy efficiency and carbon-related workgroups, associations, and initiatives: China PCF (PCR) Standard Working Group, China Energy Label Standard and Technical Committee, China Energy Saving Work Association of the Chinese Institute of Electronics, China ePCF Platform Union, China Energy Conservation Program and China Ministry of Industry and Information Technology Eco-Design Pilot Enterprises Program.

Furthermore, Lenovo worked with HP, Seagate, Cisco and MIT on a new method for calculating PCF. The goal of the project was to develop product-specific allocation methodology that link facility-wide environmental data to the specific product types being made within that particular facility. Please read the results of this project in the paper Standardizing Methods for Performing Allocation of Supplier Carbon Data for IT Products.

For more details on Lenovo’s PCF strategy and calculated PCF for a typical Lenovo notebook, desktop and monitor, please see the paper Lenovo’s Product Carbon Footprint Strategy.

Lenovo Product Carbon Footprint (PCF) Information Sheets for some of our existing products and all new products (including notebooks, desktops, monitors, all-in-ones and tablets) released after July 2015 are available here.


Lenovo also continues to minimize the use of packaging material consumption per box while driving the use of environmentally sustainable materials year by year and improve reuse of packaging and shipping materials. Actions all of which ultimately result in lower carbon emissions.

End of Life

It was estimated that Lenovo avoided in FY 2017/18 more than 62,000 MT CO2e thanks to recycling end-of-life electronic products.

Note: U.S. Environmental Protection Agency Waste Reduction Model (WARM, March 2016)’s emission factor of 2.50 MT CO2e per short ton was used for the estimate - Tool
