Inside Cisco IT

More and more businesses these days are taking steps to reduce their carbon emissions.  (Cisco is one of them, as the company met a 25% greenhouse gas reduction goal last year and subsequently upped it to 40%.)

There are several compelling reasons for doing so – some philosophical and others pragmatic.  Here are a few:

Carbon emissions should be of particular concern to anyone who operates a Data Center or lab.  These environments often account for a super-sized portion of a company’s carbon footprint because their power density is greater than other building space.

It’s no surprise, then, that the Data Center industry has developed a metric aimed at determining the efficiency of a server environment relative to the carbon emissions associated with it.  Here’s a look at the Carbon Usage Effectiveness (CUE) metric and how it’s calculated.
