According to a report released by Greenpeace International, global electronic companies must do more to end the use of climate changing dirty energy in their manufacturing and supply chains. The 18th edition of Greenpeace’s Guide to Greener Electronics evaluated leading consumer electronics companies based on their commitment and progress in three environmental criteria: Energy and Climate, Greener Products, and Sustainable Operations. The Guide scored companies on overall policies and practices to provide consumers with a snapshot of the sustainability of the biggest names in the industry.

The Indian company Wipro topped the rankings in its first appearance in the International version of the Guide to Greener Electronics. Wipro scored high points (7.1) for reducing greenhouse gas emissions and increasing its use of renewable energy, placing energy efficient products in the market and for an effective take-back policy and performance on the collection and recycling of post-consumer e-waste.

HP lost its top spot from the most recent edition of the Greenpeace Guide to Greener Electronics, and now sits in 2nd position, with 5.7 points, behind newcomer Wipro.

Dell dropped to the 5th position, with 4.6 points because it scored poorly on all Products criteria. Dell previously pushed back its commitment to eliminate polyvinyl chloride plastic and brominated frame retardants from 2010 to 2011. Yet, Dell still hasn’t removed these chemicals from all of its products as promised, and still has no phase-out date for hazardous substances.

Apple ended up in 6th position (scoring 4.5 points) mostly because of lack of transparency on greenhouse gas emission reporting, clean energy advocacy, further information on its management of toxic chemicals, and details on post-consumer recycled plastic use.

As the report points out, while the industry overall has taken several strides in the right direction, crucial and growing problems remain: more people around the world are gaining access to electronic devices, and while proper electronic take-back programs proliferate, the speed of collection is not keeping pace with the rate of consumption, creating ever greater amounts of toxic e-waste. In addition, companies have largely left unaddressed the massive quantities of dirty energy embedded in their manufacturing and supply chains, much of it coming from East Asia.
