Once you know your carbon footprint, you can invest in projects that sequester the exact amount of carbon your responsible for emitting. The investment depends on your carbon footprint.
For an individual -- like a college student -- it's usually $10-$15/month. Similar to subscribing to Netflix or a coffee and a bagel.
For a household with children, it's usually similar to their waterbill.
Compare this with the social cost of carbon. If the average American emits 17 tons, then -- according to researchers at Stanford University -- those 17 tons are causing $3,740 in economic damages elsewhere.
