ICT is both part of the problem and part of the solution to climate change. However, ICT professionals need to be made aware of the contribution of ICT to carbon emissions and training on how technology can reduce those emissions.

A study sponsored by the Australian Computer Society has shown that computers and telecommunications equipment in Australia generated 7.94Mt of carbon dioxide in 2005, 1.52% of national emissions. ICT professionals at the Australian National University set up a special interest group of the ACS to look at the issues and plan future measures. This work and questions about the extent, form and scope of the education and certification of ICT practitioners, in Australia and internationally, are discussed.

Computer makers are issuing claims as to the green credentials of their products and Australian Government agencies are now requests for tender including complex sustainability criteria. How are ICT professionals to be trained to assess such claims and evaluate these criteria?

Where does sustainability fit into the education of ICT professionals? Is this a specialization? How much should universities be required to teach undergraduates? Is energy efficiency the priority or should broader sustainability issues be covered as well? Are sustainability postgraduate qualifications in ICT viable? How will the body of knowledge be developed?

The Natural Edge Project, an Australian based independent Sustainability Think-Tank, has produced the Sustainable IT Lecture Series. This is a free education package for training ICT professionals in sustainability. The package focuses on energy efficiency and draws on case studies of real world energy saving projects.

1. Drivers and Benefits of Sustainable IT: The aim of this lecture is to discuss the drivers and benefits of Sustainable IT, particularly for the customer. Drivers and benefits range through business, economic, environmental and legislative domains.
2. Product Service Systems and the Product Cycle: The aim of this lecture is to discuss product service systems, their barriers and lessons from past implementations, as well as the opportunities to reduce energy and materials consumption in packaging and equipment through end-of-life processing.
3. Client Equipment: The aim of this lecture is to discuss a four-step process for reducing energy consumption, materials consumption and materials toxicity in client equipment.
4. Data Centres and HP Case Study: The aim of this lecture is to discuss a seven-step process for reducing energy consumption in data centres and to present a Sustainable IT case study of IT vendor HP.
5. Roadmap and Success of Sustainable IT: The aim of this lecture is to discuss the strategies, activities and actions upon which customers and vendors should focus in order to successfully transition to, maintain and promote their Sustainable IT solutions at the organisation and industry level.
6. References: This document contains the full citations for the references in the Lecture documents.

Most of the examples are from the project sponsor HP, and focus on the company's methodologies for energy reduction (but this is not just some company greenwash). The material is suitable for use in tertiary education for ICT practitioners, engineering and related disciplines. The lecture notes would also be useful for self study by practitioners interested in learning about energy saving techniques. The material is available free for educational use via an open access licence.

The Australian Computer Society hosted a presentation from TAFE NSW 17 November 2008 on their new ICT sustainability courses. Five new modules are to be offered in 2009, based on projects undertaken by students at Petersham Campus of NSW TAFE.

1. Install and Test Power Saving Hardware
2. Install and Test Power Management Software
3. Install and Test Renewable Energy System for ICT Networks
4. Implement Server Virtualisation for a sustainable ICT System
5. Install and Test Web 2.0 OS and Applications on a Low Powered Workstation Fed by Power Over Ethernet
   

The courses have a practical emphasis, with students working on PCs replacing components with lower power ones, including low power motherboards and flash drives. The students may also install solar panels and a wind generators and modify PCs to run from batteries.

As well as hardware, the students learn about using software utilities to configure energy saving settings on PCs. They also learn how to virtualise servers, including the complexities of running both Linux and Microsoft Windows operating systems simultaneously on the one server.

The courses have already provided some of the very valuable practical insights into Green ICT, such as

1. Via PC3500 Mainboard: After searching the options for low power components, the students of the TAFE course identified the new VIA board as being a good trade off between power consumption and usability. It remains an open question as to if it is worth upgrading conventional desktop PCs with low power boards, or better to replace them with a small form factor NetTops.
2. Power Management Tools, such as LocalCooling can be useful for teaching about power saving as well as implementing it.
3. ROI: The return on investment for power saving software and hardware upgrades can be calculated.
4. Learning by Doing: Students can learn by carrying out work such as upgrading PCs and explaining what they are doing while working in teams.

The Australian Computer Society is preparing a course on Green ICT Strategies for Computer Professional Education Program. This program has been accredited globally for training ICT professionals internationally and is aligned with the Skills Framework for the Information Age (SFIA).

The course content is being Prepared online as free open access. For progress see blog entries. It may also be offered at the ANU as a "flexible" blended course, combining e-leaning and classroom work.

There is potential for collaboration between the university and vocational sectors on green ICT courses. University postgraduate management units and will not get into the level of technical and practical detail which the TAFE provides. Some professionals will want to undertake the TAFE courses, while others just need to know that they can call on people with those skills.
