$($a$)$Stay the course.$$ While there is concern that the bank is funding big offenders of climate change, the bank cannot afford to lose its traditional clientele. This clientele is a $$gold mine$$ that will be quickly grabbed by its competitors if the bank denies funding. The bank will lose revenues and market share, while the overall impact on climate change will be nil.

$($b$)$Gain time.$$ The bank will keep funding its traditional clientele, but it will quietly and modestly fund experimental green initiatives and educate competitors and the public on climate change.

$($c$)$Reorient services.$$ The bank announces that it will stop funding ecological offenders and move to fund exclusively projects and firms engaged in clean technologies. In addition, a letter addressed to shareholders, bondholders, employees and the public at large is released. Put simply, the letter acknowledges that, although profits will be drastically reduced, the bank will still generate resources to stay in business and grow, though at a more modest pace.

Question: Which of these three options would you recommend? Please briefly explain why.
