Greenpeace has questioned Nintendo's commitment to conserving our planet, saying it's found the Wii maker's response "inadequate".
"We're in continuous dialogue with all the companies we speak to, apart from Nintendo," Greenpeace's Iza Kruszewska told Edge. "The company has an incredibly poor standard of communication regarding this issue."
"What really struck me was Nintendo's response when we asked them about this. They said that their products don't create waste because... People hang onto them!
"It's a very inadequate response, and I'm surprised a serious company like Nintendo would even respond that way," said Kruszewska.
Admittedly, Kruszewska doesn't really know what Nintendo's up to; it could be leaving fridge doors open, or perhaps car-sharing and making daisy-chains.
He said this sort of silence is frustratingly common in Japan, but the results are dismal scores for Nintendo by one of the world's foremost Captain Planet crusaders.
Sony, on the other hand, should be proud.
"Sony is clearly leading the way for the console holders. The company's Greenpeace profile shows it is doing particularly well in regards to its chemicals management and take-back initiatives," said Kruszewska.
"Microsoft is just getting on board with the environment. They've just hired a sustainability team, and we are seeing movement from Microsoft with its 360 console, but the company had started from a very low base.
"But really, they have it so easy because they only make two core hardware products - the 360 and the Zune - they should really be way ahead," he added.
Did you know that Tom Cruise voiced the Captain Planet for the first episode of the cartoon? You really do learn something every day.
