Montgomery County hopes a new Ride On bus ad campaign will encourage businesses to join its Green Business Certification Program.

The county’s Department of Environmental Protection, Montgomery College and the Montgomery County Chamber of Commerce showed off the new ad last night in North Bethesda before the Chamber’s annual awards dinner.

It reads, “Mommy and Daddy: Where do you work? Get certified. Their future depends on it.” It also includes the 43 certified members.

The program certifies businesses that attempt to reduce energy and waste, prevent pollution, manage runoff and water use and use efficient travel and transportation methods. The program recently partnered with the University of Maryland’s Smith School of Business’ Center for Social Value Creation, which will match up the businesses with graduate students who will devise further “green” opportunities.

Nonprofit business incubator Bethesda Green, investment company Calvert Investments, the Bethesda location of tax firm Cohn Reznick, synagogue Beth El and Congressional Bank on Rock Spring Drive are the five Bethesda organizations in the program now.
