Is your Carbon Offset Tax Deductible?

Yes! Cool Effect is a 501(c)3 nonprofit organization. Your purchase is tax deductible in the U.S.


If you’re in a co-working space, estimate 100 square feet per person. If you are in a standard office, estimate 150 square feet per person.

If possible, group employees into “full.” For example, if you have 2 part-time employees who each work 50%, then count that as 1 employee. You can add part-time employees up to 2 decimal points. For example, a part-time employee who works 10 hours a week would account for 25% of a full week and can be logged as .25.

How Reducing Carbon Slows Climate Change

Carbon dioxide acts like a greenhouse around the earth, trapping the sun’s energy and warming the planet’s surface. As carbon levels rise, our climate changes.
