Four Finnish companies have been included in the Dow Jones Sustainability Index (DJSI World), which measures the efforts of technology companies to develop environmental and social sustainability.
DJSI World comprises 316 companies; this year's Finnish inclusions are oil company Neste, communications giant Nokia, technology firm Valmet and energy manufacturer Wärtsilä.
Additionally, the Finnish forestry company UPM-Kymmene was listed in the index's European counterpart, DJSI Europe.
In the business world getting into the Index is seen as a considerable achievement.
"Being included is a significant recognition of Wärtsilä's tireless work for sustainability," says corporate relations director Marko Vainikka.
Valmet was chosen for the third year running, and CEO Pasi Laine chimes in.
"Remaining in the DJSI is an excellent achievement for Valmet," he says. "It shows that we have been able to improve our methods for sustainability year on year, which is in fact a central criterion for being included."
The Dow Jones Sustainability Index was founded in 1999. New companies are added every year, and old ones are also dropped.
The largest companies worldwide that were added to the DJSI this year were networking equipment company Cisco Systems, oil titan Shell and software company Adobe Systems. The biggest to fall from the Index were Korean electronics company Samsung, processor manufacturer Intel and British American Tobacco.
