The reason why banks "care" about the "environment" is so they can make you lower your energy consumption and inflate your currency harder to rob more from you.

Energy is the primary factor of production, and manifests first and most strongly the effects of increasing the supply of money.

By making people think they are doing something good, they get to rob the people of even more wealth than they could have.

The entire schtick of the recycling bins, the leaf logos, the pretty pictures of plants is nothing more than a ruse to distract you from their ever increasing greed, and pilfering of your future.
