Greenpeace has released the 18th edition of its "Guide to Greener Electronics."
The guide, which analyses and ranks the environmental policies and practices of 16 technology companies, is topped by Indian outsourcing firm Wipro, with 7.1 points from a possible 10, thanks to its dedication to renewable energy sources and sensible product take-back schemes.
HP (which topped 2011's list) and Nokia come in at second and third, with 5.7 and 5.4, respectively, while BlackBerry manufacturer RIM languishes in 16th position, with 2.0.
HP received commendations for discouraging the use of raw materials, such as tin and tungsten, sourced from conflict areas, while the high level of Nokia's products' energy efficiency also proved a key factor.
Samsung, which is improving gradually, rose from last year's guide to seventh, while Dell and Apple fell to fifth and sixth, respectively.
Apple actually received the same score as last year, but suffered because some of its competitors improved around it. The Cupertino company's "lack of transparency on GHG [greenhouse gas] emission reporting, clean energy advocacy, further information on its management of toxic chemicals, and details on post-consumer recycled plastic use" worked against it, though it received praise for its avoidance of polyvinyl chloride plastic (PVC) and brominated flame retardants (BFRs).
Dell, on the other hand, still hasn't removed these chemicals from all of its products, despite promising to do so by 2011. However, the company managed to bag top marks for its commitment to reducing GHG emissions.
RIM, which "lacks both a comprehensive clean electricity plan and a target to increase renewable energy," managed to improve the efficiency of its products but has little else to boast about.
Controversy surrounded the MacBook Air and Apple's July decision to withdraw its products from EPEAT certification. However, the laptop met green standards and Apple made a U-turn amid customer criticism.
