Day to Day
…in that order!
Obviously, walking and biking are the most environmentally friendly forms of transportation since the only energy required is your own. If your campus is too large to walk from class to class, bring a bike and bike lock to school. Most campuses these days support green transportation (thus biking) and provide bike racks at convenient locations all over campus. Taking the campus tram is the next best way to get around extremely large campuses.
The same order of things applies to getting to and from school. If you don’t live on campus or close enough to walk, try finding a cool bike route. They are often a lot nicer than one would expect. You can start with biking just one or two days until you build up stamina. If that’s not an option, check your school tram routes. All of these methods will greatly reduce your carbon footprint as well as save you gas money. If trams aren’t available, make sure to find other students to carpool with. Also, try to support all alternative transportation events like bike to school day since they bring a ton of awareness to the cause.
