WASHINGTON--(BUSINESS WIRE)--March 9, 2007--Sustainable Business Network of Washington (SB NOW) announced today that Calvert has joined and become the first sustaining member of the Sustainable Business Network of Washington (SB NOW), a non-profit group with over 65 members that brings together community leaders from business, academia, government and the not-for-profit community to advance and advocate socially responsible business.

"The Sustainable Business Network of Washington is helping to build a better National Capital region by bringing together opinion leaders and successful entrepreneurs who have combined their desire to do well with the need to build a better world," said Kathy Torrence, Vice President, Corporate Social Responsibility and Community Partnerships of Calvert. "SB NOW helps support the development and maturation of sustainable businesses.

It also helps to bridge the gaps between business, government and not-for-profits by focusing on shared values and creating win-win scenarios, in order to help make the region a better place to live and work."

"More and more people are recognizing that there is no one solution; rather working together we can drive the changes that we want and need as a society, especially here in the 'capital of capitalism'," said SB NOW Executive Director Michael Mielke. "We are pleased that Calvert, which offers one of the largest families of socially and environmentally responsible mutual funds, has made this commitment to invest in our growing organization."
