Notes and Calculation Details
Note 1: All estimates of carbon footprint are uncertain. Lenovo reports the 95th percentile of the carbon footprint estimate to reflect this uncertainty. For this product, the estimate has a mean of 289 kg of CO₂e and a standard deviation of 70 kg of CO₂e. For a quantity following a normal distribution, the 95th percentile value is equal to the mean plus the standard deviation multiplied by 1.64. Other organizations might report this value as 289 +/- 70 kg of CO₂e.
This PCF was generated using the Product Attribute to Impact Algorithm (PAIA) model, Version 2017-7-29, Date: 2017-7-29 (Product Type: Notebook). The model is © Massachusetts Institute of Technology's Materials Systems Laboratory, August 2012. For further details, please refer to the [Link to Document].
This calculation was based upon a Lenovo IdeaPad 3 17IIL05 with the assumptions and configuration described in the calculation assumptions on the next page.
This pie chart provides the percent contribution of the mean value for each element of the analysis for the full life cycle CO₂e impacts of the product. Individual elements displaying 0% are less than 0.5%.

Notes on Life Cycle Analysis (LCA) Phases
Life cycle phases included in the streamlined Product Attribute to Impact Algorithm (PAIA) Life Cycle Analysis (LCA) can be grouped into four categories: Manufacture, Transport, Use, and End of Life. Below is a brief description of each phase.
Manufacture
This life cycle phase captures emissions generated during the extraction, production, and transport of raw materials, the manufacture of components and subassemblies (including the product packaging) and product assembly.
Transport
Emissions included in the transport phase include all those generated during the air, ocean or land transport of finished or semi-finished Lenovo products between Lenovo facilities and from Lenovo facilities to customers.
Use
In-use energy consumption is calculated in accordance with the U.S. Environmental Protection Agency's Energy Star® Typical Energy Consumption (TEC) methodology. Calculated energy consumption is then used in combination with average emissions factors for the designated country of use to calculate emissions.
End of Life
It is assumed that a designated portion of the product (see table above) is recycled at the end of the use period determined in the TEC methodology. It is also assumed that the balance of the product waste materials is disposed of by landfill. Emissions generated during the mechanical destruction, separation and transport of end-of-life materials are included in the calculation.
Document Scope and Validity
Product scope of this sheet includes desktop computer, integrated desktop computer, notebook computer, monitor and tablet. This document is only valid in connection with "THE ECO DECLARATION" of the specific product.
