The past week has marked the launch of the third annual State of Green Business report, our in-depth look at the actual impacts that companies are having on 20 different areas of business activity.

The IT-related news from this year's report is a mixed bag: While the growth of certified green electronics from Energy Star and EPEAT marks a promising trend, we're still failing to recycle a significant chunk of all the old electronics we're discarding.

You can read our coverage of IT issues from this year's report in "IT Aims to Save the World," and on a more green IT 2.0 front, in "Energy Efficiency Gains Horsepower." And be sure to read my coverage of the IT-centric panel at the State of Green Business Forum, and we've collected a handful of IT tools from panelists at the event.

Speaking of Energy Star, according to EPA officials, the new certification for data centers may launch as early as June. The certification will look largely at PUE as a measure of energy efficiency, but other factors will be included as well to round the certification out.

These tools and resources from some of the world's largest IT companies serve as a companion to the discussion at the State of Green Business Forum 2010, looking at how technology can address  the 98 percent of the world's CO2 emissions it is not directly responsible for.

This survey from Info-Tech measures measures sentiment towards climate change, green IT, and how IT is reacting to environmental issues, and compares regional differences in adoption of green IT practices.

The MIT Energy Conference brings together leaders in the fields of technology, policy, industry, and finance to develop solutions for the tremendous challenges present in today's energy markets.
