The checking account, called EcoCash, encourages online banking but allows five free paper checks per month at ShoreBank Pacific.

The bank also donates a portion of fees associated with the account to carbon offset programs, which are designed to reduce greenhouse gas emissions, the bank said.

"After building our sustainable business banking programs, it was time to turn our attention to the depositors who have so loyally supported our values and want to establish ShoreBank Pacific as their primary account," said David Williams, president and CEO. "Of course we had to create an account with a sustainable twist. Our solution was to not only create an easy, affordable way for people to bank with us, but to also help offset the environmental impact of checking accounts that most banks ignore."

ShoreBank Pacific is headquartered in Ilwaco, Wash., and has offices in Portland, Ore. and Federal Way, Wash.
