While more IT companies are now taking significant steps toward going green, there is still a lot of work to do to protect the environment, says Greenpeace International, an environmental activist group.

During the release of the 7th edition of Greenpeace's Guide to Greener Electronics, Greenpeace Southeast Asia Toxics campaigner, Beau Baconguis, said that many companies are already at the 7/10 mark (with 10 as the highest 'green' score) -an indication that companies have already started moving toward green IT.

Samsung Electronics and Toshiba, shared the top spot in the latest edition with a score of 7.7 out of 10. Samsung's consistency in its practices and policies kept the company score stable, while Toshiba climbed from the sixth spot through its improved score in Individual Producer Responsibility (IPR), which is the criterion on how each company takes care of the e-waste from its own discarded products.

The two companies surpassed mobile phone manufacturer, Nokia, who should have been on top with a score of 8.3 but was penalised because of shortcomings and inconsistencies in its take-back or collection.

Baconguis said they will be expanding the study to include energy consumption next quarter, where they will rank brands against a new energy efficiency criterion to encourage the industry to reduce its carbon footprint.

"Most electronics brands are rising to the toxic chemical and e-waste challenge. It is now time to raise the bar and challenge the industry to take a holistic approach to its practices and operations," said Baconguis, adding that companies have to take responsibility for the entire lifecycle of their products. He said that if companies start their 'greening' activities in the first stage of the product lifecycle, then electronic wastes will be reduced, if not, nonexistent.
