Washington business owner Dale Carlson of Tacoma wrote a letter to Republican state Representative Ed Orcutt questioning a new bike tax the state legislature is considering as part of a transportation package. In response, Orcutt claimed cycling causes greater carbon dioxide emissions than driving.
"Also, you claim that it is environmentally friendly to ride a bike. But if I am not mistaken, a cyclists [sic] has an increased heart rate and respiration. That means that the act of riding a bike results in greater emissions of carbon dioxide from the rider. Since CO2 is deemed to be a greenhouse gas and a pollutant, bicyclists are actually polluting when they ride."
