Sony and Sony Ericsson have come out on top of the latest Greenpeace Guide to Greener Electronics, although most companies saw their scores drop due to a new ranking system based on wider criteria.Sony Ericsson, which shared first place overall with Sony, became the first company to score almost top marks in the chemical sector, having removed PVC, antimony, beryllium and phthalates from its products. It missed a perfect score because of “unreasonably high threshold limits for brominated flame retardants in products that are allegedly BFR-free.” Sony scored lower on the chemicals criteria because it has fewer models on sale that are free of the substances targeted by Greenpeace. Nokia was ranked third, and once again would have come first were it not for inconsistencies in its product take-back and recycling program. Samsung and Toshiba, which led the previous edition of the guide, fell due to low scores in the new energy criteria. Toshiba ranked slightly better on energy due to its commitment to an absolute reduction in greenhouse gas emissions. The Greenpeace Guide to Greener Electronics was first published in August 2006. It ranks the 18 biggest makers of PCs, mobile phones, TVs and game consoles.
