When it comes to credit card offers, it is rare that the company boasts about its “green” record. And for many people, the idea of responsible personal finances – from ethical investing to buying fair trade items – is starting to include the credit cards they use.

There are some credit card companies that offer you the option to donate a portion of your purchases to worthy causes. American Express has the RED card, and other credit card issuers, including MBNA, have similar programs. You can get a credit card that donates to the World Wildlife Fund, or a card that gives money to efforts to fight poverty.

But beware! Even though you are donating to worthy causes, some credit card issuers are deeply involved in harmful practices. If you are interested in choosing cards from companies that have better environmental track records, Real Money offers this scoop:

• JP Morgan Chase has adopted a policy to address deforestation and global warming. JP Morgan Chase owns Citibank, Bank One and Chase and Bank of America.
• Morgan Stanley (which owns Discover) is among those dinged for poor rain forest action policy.
• Wachovia, Merrill Lynch, Credit Suisse First Boston and Wells Fargo also have poor records.
