Students will be divided into groups and will come up with proposals of how to reduce the carbon footprint from carbon dioxide released from vehicles. The groups will represent different ways to reduce the carbon footprint via an alternative fuel source or a new technology. They will debate their findings to determine the direction that the city council should move towards to reduce the carbon footprint.
