I seem to have missed this major announcement last week that the EU launched a "Green" Code of Conduct for Data Centers. The Code of Conduct was created in response to increasing energy consumption in data centers and the need to reduce the related environmental, economic and energy supply impacts. It was developed with collaboration from the British Computer Society, AMD, APC, Dell, Fujitsu, Gartner, HP, IBM, Intel, and many others.
According to the PDF overview, "The Code of Conduct was been created in response to increasing energy consumption in data centres and the need to reduce the related environmental, economic and energy supply security impacts. The aim is to inform and stimulate data centre operators and owners to reduce energy consumption in a cost-effective manner without hampering the mission critical function of data centres. The Code of Conduct aims to achieve this by improving understanding of energy demand within the data centre, raising awareness, and recommending energy efficient best practice and targets."
Those who choose to abide by the voluntary Code of Conduct will have to implement energy efficiency best practices, meet minimum procurement standards, and report energy consumption every year.
