Greenpeace has slammed Nintendo's commitment to conserving our planet as "inadequate".
Iza Kruszewska from Greenpeace said: "We're in continuous dialogue with all the companies we speak to, apart from Nintendo".
"The company has an incredibly poor standard of communication regarding this issue".
Apparently Nintendo is convinced that its products don't cause any harm to the planet as people keep them and never throw them away.
"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", added Kruszewska.
Bad scores for Nintendo all round then. Sony on the other hand, is in Greenpeace's good books, while Microsoft is just about getting there.
"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.
Previously, Greenpeace has described Nintendo's green policies as "non-existant" and ranked the console owner at the bottom of the Greenpeace global assessment of "green" technology companies.
