Since I didn’t use the moped to do anything but smile alot and burn out on some gravel, I can’t really say that my use of a moped cut down on my carbon emissions.  Although I could argue that the fun I had was equal to snowmobiling. By recreating using the moped instead of the Snowmobile, I did burn significantly less fuel than I would have towing my sled to the mountain and burning that wretched two-stroke that we have to deal with.
