From Facebook and LinkedIn to CrowdVine and Twitter, a growing number of companies are enlisting the power of social media for their sustainability efforts.

Sustainability software firm Enablon unveiled a social media tool this week to add to their arsenal. It's called Wizness, which Enablon bills as a platform for wise business.

The company launched the public beta version of Wizness at the BSR Conference 2011 in San Francisco Wednesday. In a live demo this morning at the event, Philippe Tesler, Enablon's co-founder and North America president, explained how Wizness provides a social media platform to help stakeholders engage in the name of sustainability.

"This is much more than a social network," he said. "It's a collaboration platform. It's there to enable collaboration between companies and one another, between companies and experts, and between individuals working at these companies."

The layout of Wizness includes a wall similar to what you'd expect from a social media platform, where users can communicate through posted messages and links that filter down the page in real time.

Companies and organizations can use Wizness to tell their sustainability story, along with their actions, challenges and quantitative data, and actually engage in dialogue with their stakeholders. At the same time, they can shape and control their image on their profile page and filter content based on specific audiences, such as supplier or employee users.

Wizness allows sustainability professionals to join communities of experts with whom they can share best practices. Groups can also use Wizness to link key players working on industry initiatives, and even content providers may use Wizness to push out material and respond to questions.

So far, Wizness has more than 250 member companies, including UPS' Elizabeth Rasberry, who is an early adopter of Wizness who hopes it will improve communication with stakeholders.

"My main objective was to filter content relevant to environmental issues and possibly engage in some dialogue along the way," she said in an email. "What intrigued me was the ability to set up different stakeholders and be able to discuss various topics."
