  13. 13. Remarks from the respondents 13 I 22Measures to be taken •  “Stimulus by means of governmental grants or tax regulation might be useful.” •  “We need more measurement data! Does it really matter?...” (and on what scale?) •  “Cloud infrastructures and PaaS/SaaS make the best contribution to energy-efficient IT.” •  “Make clear where you set your systems boundaries before making an environmental assessment!”Interesting observations •  “Well as usual Green is a big label which everyone use for marketing and is not really working as its supposed to, so I hope yours is not the same…” •  “Until today, I have never thought much about it, but it´s a very interesting subject.” •  “I think its a quite unknown field for consumers and as one of them I would like to be informed.”Results of the “Green Software Awareness Survey” – Miguel Ferreira – 2011/06/07
