IDC has found that there has been a climate change in enterprise IT buying decisions. In a welcome change from the tide of vendor-sponsored green surveys, heavyweight IDC reports that IT executives' buying decisions are going green.

The findings come from IDC's Enterprise Panel, a fully IDC-owned and operated online group of professionals in IT and line-of-business occupations who are involved in the technology purchases of their employing organisations. There are 5,000 active members spread across small to very large businesses around the globe.

The green IT survey revealed that the great majority of executives, 80% of them, think that green IT is growing in importance for their organisation. Nearly half of them, 43%, say they consider a vendor's "greenness" when selecting their suppliers.

Other findings include:-

- One half of the panel respondents claim that “reducing their organization's environmental impact” was important or very important to senior management,
- 42% of respondents said that IT will play a lead role or an important role in their organisations' efforts to reduce their environmental impact,
- One-third of respondents rated an IT supplier's "greenness" as important or very important to the buying decision,
- 81% of respondents identify green products' ability to reduce operating costs as the most important reason for considering a supplier's greenness.

Frank Gens, IDC's SVP of research, said: "The spread of green IT continues as organisations gain a better understanding of the benefits of going green. Once a distant afterthought, economic advantages, including reductions in operational costs, are driving green IT adoption."

From energy efficiency to ease of recyclability, a product's greenness is becoming a more important economic component in the IT buying equation. But it's the money savings that attract customers, not greenness per se. No climate change there then.
