Windows 11 hardware requirements and refurbished computing sustainability

The compatibility requirements for Windows 11 are driving discussions regarding hardware longevity and environmental impact. Testing on older hardware, such as an Intel Core i3-5005U processor, demonstrates that while modern operating systems can run on older architectures, everyday tasks like video conferencing and heavy multitasking can significantly strain system resources.

This hardware limitation often forces users to replace functional devices because Microsoft does not officially support older processors. From a sustainability perspective, manufacturing accounts for a vast majority of a computer's carbon footprint. For instance, major manufacturers like Apple, HP, and Lenovo report that between 71% and 89% of a device's CO2 equivalent emissions occur during production.

Using refurbished devices can mitigate these emissions. Research from Fraunhofer UMSICHT indicates that refurbished notebooks can save approximately 31% of CO2 compared to new purchases, while refurbished desktop PCs offer an 18% reduction. However, consumers should be aware that condition grading for used hardware is not standardized and warranty periods may be limited to one year by agreement.
