Few of us think about how our banking affects the environment but, in reality, putting your money with a green-minded financial institution may be one of the best things you can do to help conserve land, protect air and water, save endangered wildlife and mitigate climate change. Banks (owned by shareholders) and credit unions (owned by the customers) lend and invest some of the deposited funds they are holding, which is how they're able to pay interest back to you. A bank or credit union that limits its investments to sustainability-oriented companies and institutions is well on its way to being considered green. Responsible options include Amalgamated Bank, Sunrise Banks, City First Bank of DC, Beneficial State Bank, and Southern Bancorp.
