Every year that Greenpeace releases its "Guide to Greener Electronics", one company is always at the bottom. That company is Nintendo.
According to Greenpeace, "Nintendo remains in last place with a pitiful 0.8 points out of 10, scoring zero on all e-waste criteria."
Why did Nintendo score so low? Not providing information on things like "amount of renewable energy used" probably has something to do with it. Greenpeace didn't have information on multiple sections for Nintendo.
Instead, Nintendo's website has information regarding its social responsibility and environmental activities. Nintendo's already green, anyway with green being buckets of money.
In comparison, Microsoft ranked 2.7/10 and Sony ranked a decent 5.5/10.
