We knew from our previous reporting that Greenpeace wasn't exactly a fan of Steve Ballmer, but today the environmental group quantified its option, giving him seven out of a possible 100.

That's the score received by the Microsoft CEO in a new Greenpeace report card ranking the top technology executives on their environmental records. The report dings Ballmer for not speaking out on the environment. It also takes the company to task over its emissions reduction targets and political advocacy.

As noted by Joe Tartakoff of PaidContent.org, the timing of the Greenpeace report card is ironic, given Ballmer's high-profile purchase of a Ford Fusion Hybrid yesterday. He previously had been spotted driving a Range Rover, so it's too bad for him that Greenpeace doesn't take into account any improvement in personal driving habits.

Microsoft does get a top score for renewable energy usage, but that didn't weigh heavily in the score.

The Redmond company has been taking a series of steps to improve its environmental standing under the leadership of chief environmental strategist Rob Bernard. Ballmer also sent out a companywide memo in March stressing the importance of the environment, but he didn't address environmental issues during his high-profile Consumer Electronics Show keynote earlier this year.

Sightline Daily cast a critical eye on Microsoft last week, saying the company has yet to "stand up for climate policy at the state or national level."

To be sure, the entire technology industry has lots of room for improvement, according to the Greenpeace report. The top exec on the list, IBM's Samuel Palmisano, gets only a 29 out of 100. Those below Ballmer on the list are Sony's Howard Stringer, Sharp's Katsuhiko Machida and Toshiba's Atsutoshi Nishida.
