According to Peter Henderson over at Reuters’ Environmental Blog, Bank of America’s recent decision to stop financing companies that use mountaintop removal for coal mining has the attention of at least one other major financial institution.

Now that Bank of America is cutting back on lending to mountain top removal mining companies, citing the environmental costs, rival Citigroup is weighing its options.

“Bank of America’s announcement has just been released so Citi will study the content,” the bank said on Friday. Citi and Bank of America were prime targets of Rainforest Action Network and others for their support of mountaintop removal mining for coal in Appalachia.

Lot tougher to tear down a mountain if no one will pay for it. banks are all about investing money, and if they see mountaintop removal, or, even better, coal mining in general as a bad investment, it’ll be a step step towards ending our reliance on dirty coal.
