NEW DELHI: Wipro, the IT group, has better environmental credentials than firms like Hewlett-Packard, Dell and Apple, according to a report from Greenpeace covering the technology sector.

The not-for-profit organisation assessed 16 big manufacturers, rating their activity related to emissions, the use of hazardous or unsustainable materials, and recycling of obsolete lines.

Wipro, based in Bangalore, logged 7.1 points overall. Plans to cut its greenhouse gas output by 44% from 2011–15 are ahead of schedule, while 52% of its products reach a high level of energy efficiency.

"Wipro is committed to the cause of offering environment-friendly products, processes and systems," Raghavendra Prakash S, business head of Wipro's systems and technology arm, told Mint. "We have made adequate investments in various programmes in the area of green sustainability."

The company also provides 17 direct sites and 300 authorised centres run by third parties for collecting old products. It has even attempted to encourage other firms to adopt similar policies.

"Wipro has the set the bar for the sector and it's time for its competitors to beat that mark," Casey Harrell, an analyst at Greenpeace, said.

Hewlett-Packard, the world's biggest manufacturer of personal computers, claimed second position in the rankings on 5.7 points, followed by Nokia, the telecoms group, on 5.4 points.

Acer, the Taiwanese company, registered 5.1 points, beating Dell, its US counterpart, on 4.6 points. Apple, the creator of the iPhone and iPad, came next on 4.1 points.

Research in Motion, which makes BlackBerry mobile phones, secured two points and was bottom of the charts. Toshiba and Sharp, the Japanese electronics specialists, posted 2.3 points and 3.1 points in turn.

Harrell suggested that the technology industry as a whole had made discernible progress across most of the areas analysed, but still had work to do.

"The next big challenge for the tech sector is to address the dirty energy embedded in the devices' manufacturing and supply chains that causes climate change," he said.

"With an expected $1tr in sales in 2012, the industry can prevent a lot of global warming pollution if it moves to clean energy in its manufacturing processes."
