Does Greenpeace ever get its facts right?

Here is a piece that claims that Greenpeace rarely if ever gets its facts correct:

Greenpeace recently released their "Guide to Greener Electronics," rating fourteen consumer electronics vendors. . . . . Do the claims have any merit? . . . . While the Greenpeace report attempted to rank vendors based upon useful and practical criteria, the actual scorecard and the methods used to collect information for their report were sloppy and incompetent. This should come as no surprise to anyone aware of Greenpeace activities. . . . .
