We want to be more sustainable, but most of the actions we take seem so inconsequential relative to the size of the problem. One action that we can take that has real impact is placing our mortgage at a sustainable bank.

It is a myth that by choosing a sustainable bank, you will pay a higher interest rate on your mortgage. In fact the sustainability of the bank has no impact on the interest rate they charge. Banks are incentivised to be sustainable by the demands of super funds.
