Calculate your environmental footprint
using Envirofootprint’s CO2 calculator.

TCU’s Envirofootprint.org provides a simple calculator to calculate your carbon dioxide emissions.  The calculator estimates your carbon footprint and recommends a specific donation to offset your footprint using the secure TCU epayment system.  Your tax-deductible donation will be used to purchase purple bikes for the TCU Purple Bike Program (PBP) so students can commute to and from TCU by bike rather than driving an automobile, thus reducing everyone’s carbon footprint.   The TCU PBP has 50 bikes and over 150 students are on the waiting list.
