The "Green Ranking" by world-lovin' Greenpeace rates the world's consumer electronics industry to determine which company, in quarterly periods, is the most eco-friendly. After returning CEO Michael Dell challenged other electronics manufacturers to provide "takeback" policies on throw-away, useless hardware, it seems that China's laptop brand Lenovo outgreened just about everybody else, except itself.

Now while takeback policies aren't exactly new, only EU member nations have strictly enforced the recycle old hardware policy by asking electronics companies to offer discounts on newer hardware purchases as old, unusable parts were traded in. Greenpeace hopes that companies will adopt this policy worldwide, as did Dell.

Sony (and Sony-Ericsson) are now also complying with chemicals for silicon doping and fire resistance with their elimination of beryllium and phthalates. Unfortunately for Earth-lovers and Captain Planet, only 14 companies are currently included in the rankings.

As a big surprise to all, Lenovo, a China-based firm for electronics and mobile computing, has leaped from last place to top place, despite the massive amounts of e-waste that are generated in China. Greenpeace's International Toxic Campaigner Iza Kruszewska said:

Given the growing mountains of e-waste in China - both imported and domestically generated Â? it is heartening to see a Chinese company taking the lead, and assuming responsibility at least for its own branded waste. The challenge for the industry now is to see who will actually place greener products on the market.

Lenovo could possibly lose the number one spot if the next product that it puts out to market is not free from the worst of chemicals. The top five most eco-friendly of e-companies are as follows:

1. Lenovo
2. Nokia
3. Sony Ericsson
4. Dell
5. Samsung

The ranking takes into consideration the equal treatment of all customers, so if any double-faced takeback policies have been reported, companies suffer rank drops all across the boards. Unfortunately, Apple is the last of all the companies. But good news: Apple hasn't dropped a spot ever since!
