A popular children’s song has a refrain - “the more we get together the happier we’ll be” - that may sound like a simplistic formula for solving the complex challenges of climate change and sustainability. But if any area is ripe for sharing and collaboration among organizations, it’s green innovation.

“We all want to save the planet, and the problems are bigger than any one firm, sector or country,” says Dr. Sarah Slaughter, coordinator of the Massachusetts Institute of Technology Sloan Sustainability Initiative. In that spirit, several major corporations have taken inspiration from the open-source software movement and are experimenting with forums for sharing environmentally friendly innovations and building communities around them. The first such effort, the Eco-Patent Commons, was started in January 2008 by I.B.M., Nokia, Pitney Bowes and Sony in collaboration with the World Business Council for Sustainable Development.

The concept is straightforward: Companies pledge environmental patents to the commons, and anyone can use them - free.

Many patented environmental technologies are not strategic, so sharing maximizes the social benefit without sacrificing competitive advantage, says Wayne Balta, vice president of corporate environmental affairs and product safety at I.B.M. For instance, I.B.M. contributed a recyclable cardboard packaging insert that requires less fossil fuel to create and transport than the foam inserts that are now commonly used.

Other examples include a DuPont method for better detecting pollution in soil, air or water by using a microorganism that produces light when exposed to a pollutant. There are also methods from Xerox for removing toxic waste from contaminated groundwater, as well as a cleaning technique for semiconductor wafers from I.B.M. that uses ozone gas and eliminates chemical contaminants that result from other processes.

By assembling these patents in one easily accessible location - anyone can search through them on the council’s Web site - the hope is to encourage their widespread adoption, particularly in the developing world. Since its start, the commons has grown to 100 patents from 31, with 11 companies now participating.

Although there are no formal mechanisms for tracking who has used the commons, participating companies are sometimes contacted by users. For instance, Mr. Balta said that Yale had put into effect an I.B.M. method for decreasing the use of hazardous solvents in its quantum computing device research. The Creative Commons, a nonprofit organization that previously developed licensing programs to help in sharing creative and scientific content, is also planning to branch out into the environmental arena.

In collaboration with Nike and Best Buy, it plans to start a sharing initiative, the Green Xchange, in early 2010. The program will include both patented technologies and forums for continuing exchange of innovations such as Best Buy’s system for rating the sustainability of a supply chain.

Companies that contribute patents to the Green Xchange will have the option of charging users a fixed annual licensing fee and can also restrict any licensing by rivals or for competitive use.

“We don’t depend on altruism,” says John Wilbanks, GreenXchange coordinator and vice president for science at Creative Commons. “This system helps the environment while enabling a firm to make money from patents in applications outside its core business.”
