How will my donation be used?

Your online donation will be deposited in Exaquest Carbon’s general fund. This means that your donation will help support all of Exaquest Carbon’s activities, including our scientific research, public outreach, fundraising, and other operations.

Exaquest Carbon has no employees, rents no office space, and does not pay any compensation to its directors or officers. In other words, Exaquest operates on a shoestring budget, and we do everything we can to maximize the fraction of your donation that is spent on our core mission — i.e., conducting scientific research and then sharing our results with the world.
