COLUMBUS, Ohio- An Ohio gas company is trying to encourage customers to "go green."

Columbia Gas will donate $10 to the Nature Conservancy for every customer who switches to paperless e-billing up to $200,000.

The Nature Conservancy works to rebuild the Atlantic Forest in Brazil as a part of its Plant a Billion Trees program.

Columbia's minimum contribution will be $100,000 and plans to present a check to the Conservancy program by April 22, 2010, which is Earth Day.
