Px3 conducts computer life cycle assessment (LCA) for leading global end user computing device manufacturers. Our LCA services include both focused energy consumption measurement and full product carbon footprint reports quantifying production, delivery, use-phase and end of life greenhouse gas emissions.

Unlike previous methodologies that base use-phase calculations upon no-user present modes such as off, sleep and idle [1], our PhD research has created an advanced methodology capable of recognising the impact of human-computer interaction upon energy consumption.

Doing so enables end user computing device manufacturers to create carbon footprint data that represents a valid example of scope 2 emissions that can be expected when the computer is used in a work environment. The practice is beneficial to both computer manufacturers and businesses when forming science based abatement targets to support net zero strategies [2,3].

From a manufacturer perspective, the practice proves highly effective for identifying and promoting computers that require less energy when undertaking interaction such as email, application access, document creation and video conferencing. The rationale being that Px3 research substantiates that when certain operating systems and system components are combined [4], as much as 57% energy consumption reduction can be experienced in the workplace [1]. A quality that cannot be identified using alternative no-user present benchmark approaches [1].

From a business perspective, the findings can be used to promote low energy end user computing device identification and adoption to support IT sustainability strategies in line with new procurement legislation [5]. Additionally, the GHG values can be used to project future IT related scope 2 emissions to assist with carbon footprint reduction planning and reporting [2,3].
