Greener computing does not simply mean minimising energy consumption of the PC during its operational life, but also during its full lifecycle from “cradle to grave”. It also means minimising material throughput i.e. recycling and re-using, and disposing of hazardous e-waste responsibly. So while much of this blog and a big part of our sustainable IT campaign is focused on energy efficiency in operations and e-waste, it is also important to review our PC procurement policies.
Consider these fast facts gleaned from some Gartner articles (see references):
- according to Greenpeace more energy can be consumed during manufacture, shipping and recycling of a PC than during its operation
- Manufacturing also uses many times the weight of a product in raw materials, from water to other potentially toxic chemicals
- PCs and associated peripherals contribute approximately 31% of worldwide information and communication technology (ICT) energy use.
In order to reduce PCs’ environmental footprint we need to match the right PC with the right user – energy-wise; we need to change our procurement policies; and we must consider disposal (as we have started to do with our e-waste campaign).
The EPEAT eco-labelling system for electronic devices covers a broad range of environmental criteria as well as the latest Energy Star specification for energy efficiency. EPEAT-certified PCs and peripherals have satisfied 51 environmental criteria, grouped into the following categories:
- Reduction/elimination of environmentally sensitive materials
- Materials selection
- Design for end of life
- Product longevity/life cycle extension
- Energy conservation
- End of life management
- Vendor corporate performance
The University should seriously consider specifying EPEAT Gold or Silver certification in its PC Requests for Proposal (RFP) and its set of procurement criteria.
