Green Wheels is a project of the Northcoast Environmental Center (NEC) in Arcata, California. Green Wheels is a sustainable transportation advocacy group that promotes the benefits of alternatives to the single-occupancy vehicle and encourages and pressures governments, businesses, individuals and institutions to make choices that reduce transportation impacts and create balanced and sustainable transportation.
Green Wheels began as a student club of Humboldt State University in 2003 when it was called the Alternative Transportation Club. In 2005, the club's name was changed to Green Wheels. Green Wheels joined the NEC in July 2007. A chapter remains as a campus club at HSU.
