No better proof of this shift comes from the Rainforest Action Network's (RAN) "Global Finance Campaign" which works to promote environmentally responsible actions.  According to RAN's website (which includes PDF's of the corporate environmental policies referred to):

After years of grassroots activism and campaigning by countless volunteers, America's three largest banks, Citigroup, Bank of America, and JPMorgan Chase, have all adopted policies that safeguard old growth and endangered forests, curb investments in climate change, and protect the rights of indigenous peoples. These new standards are important steps forward in our work to bring about a sustainable economy, but many companies are still lagging. Our task is now three-fold: First, we must hold companies like Citigroup, Bank of America, and JPMorgan Chase accountable to their commitments, ensuring that their policies are fully implemented and translate into real changes. Second, we must help the rest of the financial industry move even further towards creating a world that is responsible, sustainable, and socially just. Finally, we must support the efforts of the countless individuals around the world who are creating alternative institutions that are able to reflect the diverse needs of local communities.
