Episode notes
Your Bank Deposit Finances The Economy
- Bank deposits finance lending rather than sitting idle, creating emissions through borrowers’ activities.
- Paul Moinester says lending emissions can exceed a company’s operational footprint by 700 times.
Bank Choice Can Cut Deposit Emissions
- Banks lend roughly 90% of deposits, with major banks directing 20–30% toward carbon-intensive sectors.
- Community-bank deposits can have emissions about 80% lower than deposits at large Wall Street banks.
Ten Thousand Dollars Can Equal Ten Thousand Miles
- A $10,000 balance at a major bank produces roughly three tons of annual emissions.
- Paul compares switching $5,000 to a greener bank with an emissions reduction larger than going vegan.
