Nintendo is the worst offender when it comes to tracing the use of "conflict minerals" in its products, according to a report by advocacy group Enough Project.
Conflict minerals are materials sourced from conflict areas in the Democratic Republic of the Congo. These materials - which include gold, tin, tantalum and tungsten - are often mined by exploited workers, who in some cases are forced to work at gunpoint.
According to a report on CNN, Nintendo is the worst offender when it comes to transparency regarding the origin of materials used in their products. According to advocacy group Enough Project, Nintendo were the sole company to receive a zero rating in a report that assessed the efforts of companies to curb the usage of conflict minerals, or audit their supply chain.
Other companies shamed included Canon, Nikon, Sharp and HTC, though only Nintendo received a zero rating. "Nintendo is, I believe, the only company that has basically refused to acknowledge the issue or demonstrate they are making any sort of effort on it," said the senior policy analyst at Enough Project, Sasha Lezhnev.
While Nintendo's record is embarrassing, Enough Project says the overall outlook is more positive, announcing that other tech companies such as Microsoft, Apple, Intel, HP and Dell are making an effort to better track the source of their materials.
