Nintendo has hit back at Greenpeace’s 'Playing Dirty' report today, questioning the fact that Greenpeace claims to reveal “that the world’s most popular game consoles, Nintendo Wii, Sony PlayStation 3 'Elite' [sic] and Microsoft Xbox 360, tested positive for hazardous chemicals and materials."

A Nintendo spokesperson gave TechRadar the company’s official line on this matter this morning which is as follows:

“Nintendo has not been badly rated by Greenpeace. Greenpeace chose to conduct a survey and produce a report, which graded companies upon the voluntary submission of information.

“Nintendo decided not to take part in the survey and were therefore 'ungraded' in the resulting report. Nintendo provides detailed information regarding our compliance to EU Directives via the Consumer Section of our website and therefore we felt it unnecessary to take part in the Greenpeace survey.

"Furthermore, we fully comply with all the necessary EU Directives on the Restriction of Hazardous Substances aimed at environmental protection and consumer health and safety. Furthermore, in order to ensure our products are safe for use by young children we also take into consideration the standards applicable to toys.”
