The sustainable banking bloggers at {social compact} point us to this unapologetic spot from the UK’s Cooperative Bank:

{sc} goes on to describe that they stand behind their message with an audited ethical policy.

Here is an excerpt from the policy, updated with more rigid guidelines on Feb 2, 2009:

The Bank will extend its exclusion beyond the extraction and production of fossil fuels to those businesses engaged in the distribution of fuels with a particularly high global-warming impact, particularly unconventional oil sources (such as tar sands) and certain biofuels. The development of these fuels has the potential for significant local environmental impacts and will accelerate increases in global greenhouse gas emissions.

Is there a business case for a purposeful “no?” David Anderson, the bank’s CEO, said that, “The Bank’s Ethical Policy has led to more than £1 billion in unethical business being declined, but it has also contributed to a massive £3.8 billion net growth in our corporate lending.”
