Greenpeace, an environmental protections group, on Wednesday released the second edition of its Green Electronics Guide, which ranks 14 leading PC and mobile manufacturers on their efforts to eliminate toxic substances from their products, as well as whether the firms offer product take-back or recycling plans and to what extent, according to a Dec. 6 release on Greenpeace.org.uk.The rankings were based on publicly available information, as well as communications with the firms for various clarifications. The full scoring criteria can be found here.The Greenpeace scorecard is based on a 10-point scale and is as follows:\n\nNokia (7.3)\n\nDell (7)\n\nFujitsu, Motorola (6)\n\nSony Ericsson, HP (5.7)\n\nAcer, Lenovo (5.3)\n\nSony (5)\n\nPanasonic (4.3)\n\nLGE, Samsung (4)\n\nToshiba (3.7)\n\nApple (2.7)Finland\u2019s Nokia and Round Rock, Texas-based Dell again received the group\u2019s top rankings.Notable ranking increases include Motorola\u2019s tie for third place with Fujitsu\u2014the handset maker scored a 12th-place ranking last time around\u2014and Lenovo\u2019s jump from 13th place to a tie with Acer for fifth. Motorola improved in all criteria, and Lenovo also made progress in most areas; however, it was penalized for still including some of the most hazardous materials within its PCs and because its recycling and take-back programs still need work. Also notable is the fact that Apple Computer\u2014which prides itself on its iPod recycling efforts\u2014received the lowest ranking of all companies taken into account. The Cupertino, Calif.-based firm got \u201clow scores on almost all criteria and [made] no progress,\u201d according to Greenpeace."The scorecard will provide a dynamic tool to green the electronics sector by setting off a race to the top,\u201d said Iza Kruszewska, Greenpeace International toxics campaigner, in a statement on the group\u2019s website. \u201cBy taking back their discarded products, companies will have incentives to eliminate harmful substances used in their products, since this is the only way they can ensure safe reuse and recycling of electronic waste."The Green Electronics Guide will be updated every three months, and firms\u2019 rankings will reflect their improvements\u2014or lack thereof\u2014in reducing the level of toxic substances used within their products and their recycling efforts.The first edition of the guide was released in August.Related Link:\n\nGreenpeace Blasts HP, Apple for Toxic Substances in PCsCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
