After having its annual meeting and corporate headquarters repeatedly protested by environmental groups, it appears Bank of America (NYSE:BAC) and the rest of the banking industry may be listening.

For 2012, financing to the coal industry reportedly fell around 50%. Granted, this may be due to lack of demand as well, but environmentalists appear to be pleased with the progress. According to a recent study led by the Rainforest Action Network, Bank of America reduced its coal lending by roughly 48% -- but remained the biggest lender.
