Background of emission factor

The emission factor for the Lenovo ThinkPad P14S Gen 4 Intel laptop includes emissions from the device’s entire lifecycle. Most emissions occur during manufacturing, so using the device longer helps reduce its impact. During use, emissions come from the electricity the device consumes.

Emission factor category

Emission factors for electrical devices measure the life cycle emissions (cradle-to-grave). Emission factor takes into account emissions caused by the production, use and end-of-life of the electrical device.

Quality of emission factor

High-quality emission factors verified by an external verifier, usually sourced directly from the supplier (primary data). The factor may be a maximum of 3-5 years old and cover all greenhouse gases (CO2e).

Unverified primary data factors, as well as new and accurate average factors based on physical quantities. The factor may be a maximum of 3-5 years old.

Average, based on physical quantities, with one of the following shortcomings: more than 5 years old, only CO2 emissions, or contains many assumptions.

Inaccurate emission factors based on physical quantities that contain several of the following shortcomings: more than 5 years old, only CO2, or contains many assumptions. The newest, highest-quality spend-based emission coefficients also fall into this category.

Old and inaccurate spend-based emission factors. Their use in emission calculations should be avoided.
