Calculate the Impact of Your Savings

$ Slide to Calculate $$$

Moving $10,000 from a big bank to a climate-friendly bank like Walden Mutual is equivalent to:

  • driving 4,690 fewer miles every year in a gas powered car,
  • skipping 10 flights from Boston to Denver each year,
  • or preserving 2.18 acres of U.S. forests.a

That's an estimated reduction of 1.83 metric tons of CO2 from your carbon footprint (80.4% smaller than the biggest banks).b Instead of financing fossil fuel projects, your savings at Walden fund loans to farms, food businesses, and other sustainability-focused organizations.

  2. b Actual impact may vary. The estimates presented here are based on data from "Saving for the Planet", a 2023 study by Project Drawdown which was not specific to Walden Mutual Bank. It found the average lending impact of the four largest banks (Bank of America, Citigroup, JPMorgan Chase, and Wells Fargo) to be 0.29 tCO2-eq per $1,000 per year. The lending impact of several climate-responsible banks analyzed was found to be 80.4% smaller, averaging 0.057 tCO2-eq per $1,000 per year.
