Turns out you can fight climate change by switching credit cards

I use a cash-back credit card. Many of my purchases earn 2%. Given low interest rates, I sometimes earn more spending money than saving. (Note: I always pay off my balance. So it never bites me in the ass.)

But I had a thought. What if instead of getting cash back, I could offset my climate impact? Imagine a credit card that rewarded you with carbon offsets based on your purchases. Buying gas, for example, would yield more offsets than buying a tree at the garden centre.

It could even track your carbon emissions. After all, it would know what you bought. It could then reward you for reducing emissions. You could earn points or cash-back for taking specific climate-friendly actions. Like, double points for buying a transit pass versus gas for your car.

Well, turns out this exists. It’s called Doconomy and I just discovered it. Doconomy even has a credit card that gives you a CO2 emissions limit.

My first reaction was: damn, another idea that someone has already done! But now I’m intrigued. I’m going to check it out. If you have any experience with it, please let me know in the comments.
