Washington state Rep. Ed Orcutt (R–Kalama), a ranking member of the State Transportation Committee, argues that bicycling is bad for the environment and says bike riders should have to pay a tax to help maintain the state's roads. Orcutt made his comments in an email, which was posted by the Cascade bicycle club blog on Saturday. In the message, Orcutt states bike riders pollute the environment because they produce more carbon dioxide than car drivers. The email from the lawmaker, which was written to bike shop owner Dale Carson, goes on to say that because bike riders have an "increased heart rate and respiration," 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," Orcutt wrote in the message...Rep. Orcutt has subsequently apologized for his comments, saying that "My point was that by not driving a car, a cyclist was not necessarily having a zero-carbon footprint."
