Nokia is the world’s most sustainable technology company, according to the latest edition of the Dow Jones Sustainability Indexes.

Already rated for several years as the leader within the Europe and Communications categories, this year Nokia was also chosen as “World Technology Supersector Leader,” making it No. 1 across the entire global technology sector.

“Achieving the world number one slot across the entire global technology industry is a great achievement,” said Rick Simonson, executive vice president and CFO at Nokia, in a statement. “It reflects the continued and strong commitment by Nokia employees to sustainable business practices. We remain committed to action in this area because acting responsibly is not only the right thing to do; it is also undoubtedly the best thing for our business.”

Nokia says it has been integrating environmental and sustainable activities into the way it does business for more than a decade. Some of Nokia’s recent projects include developing dedicated mobile software for health workers to help monitor and fight the outbreak of disease in Brazil and using mobile devices and connections to deliver educational materials to children in remote or unprivileged areas in Brazil, the Philippines and South Africa.

Earlier this year, Nokia was recognized at Mobile World Congress in Barcelona, where the company received the GSMA’s first award for Outstanding Environmental Contribution. In August, Nokia was also chosen as India’s “Green Company of the Year” in the 10th Annual Voice and Data 100 Awards.

The Dow Jones Indexes rank how well corporations are integrating sustainability into their businesses.

Nokia’s brand recently ranked No. 5 in the world’s most valuable brands in 2009 by Interbrand. Coca-Cola topped the list, followed by IBM, Microsoft and GE. Google came in at No. 7, and Intel was No. 9.
