Green ICT: Trends and Challenges CEPIS Green ICT Survey – Examining Green ICT Awareness in Organisations: Initial Findings Carol-Ann Kogelman on behalf of the CEPIS Green ICT Task ForceGreen ICT is an increasingly important issue for many organisations across Europe today. This paper presents the initialfindings of research to assess how ICT Managers in different countries implement energy efficient methods in their organi-sations.

  3. 3. Green ICT: Trends and Challenges “ Since ICT Managers of organisations are usually responsible for the management of ICT HW and SW, they are ideal candidates for assessing whether a culture of energy efficiency exists in European organisations ” Force aims to achieve at least 50 respondents in each of their own countries. Such a result will achieve a fair and balanced sample of responses to create a comparative analysis of Green ICT awareness in organisations across Europe today. The data collection phase for this research is still ongoing and so far the survey has reached a sub- stantial number of countries through Task Force Members’ efforts. Here below we provide you with the initial findings so far. The survey is still open, and after reading these exciting results we en- courage you to contribute to this ground-breaking research project by taking the survey at the follow- ing link: < 1: Implementation of Green IT Practices.

This can provide useful business informa-tion that many ICT managers may find important, inorder to see how their organisation’s ICT usage &green ICT practices compare to organisations in othercountries. Members of the CEPIS Green ICT Task Forcebrought together their expertise on the topic of GreenICT and created this survey that includes over threedozen comprehensive questions. The Task ForceMembers represent over 10 different countries inEurope, including Germany, Greece, Ireland, Italy,Malta, Romania, Spain, Switzerland, The Nether-lands, and UK.

  4. 4. Green ICT: Trends and Challenges “ Over a third of organisations in Europe do not implement green IT practices, the most prominent reason given is that there is no official legislation in their countries enforcing green IT practices ” there is no pressure from management or cus- tomers to follow such practices. (see Figure 1.) 2.3 Disposal & Use of ICT Products Over half of organisations who responded to the survey do actually dispose of their old com- puters with electronics recycling companies. And just over a fifth of respondents donate their old computers to charitable organisations. (see Fig- ure 2.) Over two thirds of organisations do use recy- cled printer supplies/cartridges. Further almost half of respondents return their used ink cartridges to companies that recycle.

Of the approximately 300 responses thathave been received so far, almost three quar-ters do not have a person dedicated to this taskfor their organisation. 2.2 How ‘Green’ is your Organisation? It appears that from the responses, just overa third of organisations in Europe do not im-plement green IT practices, the most prominentreason given is that there is no official legis-lation in their countries enforcing green ITpractices. The second most given reason is that Figure 4: Restrictions to Use of Printers. “ Less than one fifth of organisations actually monitor how employees reduce their energy consumption ”8 CEPIS UPGRADE Vol. XII, No. 4, October 2011 © Novática
  5. 5. Green ICT: Trends and Challengesprinters also have a double-sided print function-ality, but only two fifths of those have the dou-ble-sided printing option as the default option. Interestingly over half of respondents con-firmed that there are no printing restriction poli-cies within their organisations. With those organisations that do have print-ing restrictions in place, almost half stated thatthe reduction measure is that "There is a spe-cific number of users that have the right to print".Some other ‘reduction measures’ from organi-sations included avoiding printing as much aspossible, and using common sense when print-ing.

During the survey ICT Managers, (the maintarget audience for this survey) are asked to de- do not monitor the energy consumption intermine the level of awareness of other employ- any of their areas such as data centres, orees within their organisations towards energy even within the whole IT department itself. Significantly, overall energy consump- tion is measured within most European or- ganisations only on a monthly basis. How- ever over a third of organisations seem to never measure the energy consumption and a significant proportion of respondents did not know if energy consumption was meas- ured or not. (see Figure 6.) ICT Managers’ decision making proc- esses in purchasing products are also inves- tigated during the survey. From the responses we have received so far, two thirds of re- spondents take into account the product’s energy consumption before deciding to pur- chase. They also rate knowing the level of en- ergy consumption of a product as important and very important. Yet almost half do not takeFigure 6: Frequency of Energy Consumption Measurement. into consideration whether the product is made of recycled materials, but those that do, rate this value as important. (see Figure 7.)efficiency. The responses so far show thatthere is an even split with regard to whetheror not computer users have been informed/trained in energy consumption reductionprocedures. In any case just under half ofall respondents agree that their employeeshave been trained in some way. Less than one fifth of organisationsactually monitor how employees reducetheir energy consumption (see Figure 5). Of those organisations that monitoremployees, around 40% noticed that theenergy consumption was reduced afterthree months. Yet two thirds did not pub-lish these results. Within their own departments, ICTManagers responded that over two-thirds Figure 7: Importance given to Knowing the Level of Energy Consumption.© Novática CEPIS UPGRADE Vol. XII, No. 4, October 2011 9

Annex: Invitation to Digital Trends 2011 – GreenICT and Cloud Computing CEPIS and the Hellenic Professionals Informatics So-ciety (HePIS), the Greek CEPIS Member Society, are co-hosting Digital Trends 2011 in Athens, on 2 December2011. This is the first Forum of its kind in Greece and hasbeen established to create dialogue on the contribution ofthe ICT sector to economic growth, increased productivity,and the advancement of a creative digital culture. In par-ticular the conference aims to focus on how the ICT sectorcontributes to the adoption of ‘Green’ and ‘Cloud’ prac-tices, and the strengthening of the overall role of profes-sionals within the business community. Digital Trends 2011 will focus on the business dimen-sion of Cloud Computing and Green ICT through offeringICT and business professionals a useful guide to the intro-duction of an organisation to a new business environment.Issues to be discussed at this event include relating to GreenICT include: How are green practices being implemented? What are the benefits of Green IT? Why are Green IT practices not implemented in manyorganisations?
