My proposal for this Earth Day 2015.

Stop using purposeless, dangerous and silly credit-risk weighted equity requirements for banks, those which allow banks to earn higher risk adjusted returns on equity when lending to those perceived as safe than when lending to "the risky".

Purposeless: because major bank crises never ever result from excessive exposures to what is perceived as “risky” but always from excessive exposures to what was erroneously perceived as “absolutely safe”. 

Dangerous: because that completely distorts the allocation of bank credit to the real economy.

Silly: because why on earth should we taxpayers lend our support to banks if their only goal is to act as safe mattresses to stash away money in. Better to build a super-safe storage facility then.

Begin using more purposeful potential of planet-earth sustainability, job generation and poverty reduction weighted equity requirements for banks.

That way our banks will earn their highest risk adjusted returns on their equity when financing what is deemed useful for the society.

That way it makes sense for us taxpayers to lend our banks the support they need, in order for these to take the astute risks we need for the world to move forward in a sustainable way generating jobs and poverty reduction.

Who shall you tell about this proposal? All bank regulators starting by the Basel Committee for Banking Supervision and the Financial Stability Board; and to multinational entities such as the UN, IMF, and World Bank.

If they do not listen to you, at least force them to try to justify why they are supporting current credit-risk weighted equity requirements. These only impede the access to bank credit of "the risky", thereby killing opportunities and increasing inequalities.
