Vehicle Travel
Short Tip: 
Using Carpools and Vanpools.
Full Tip: 
Whether for work, attending an event, getting kids to school and back, start or join a carpool or vanpool.
Impact: 
There are several impacts that can be significant, e.g., reduced fuel consumption and commensurate reduction in greenhouse gas emission, reduced vehicle wear, reduced road wear, not to mention the positive social aspects of making a difference and creating an opportunity for more social contact. Clearly the savings vary by distance, number of participants, etc.
How: 
Do a minimal amount of research with friends, company bulletin boards, PTA meetings, etc. If there isn't a carpool or vanpool that meets your needs, post to see what interest you can garner and start the carpool or vanpool. Use the Internet to give you best practices for starting and managing a carpool or vanpool. If going to an event, find out who else is going and see if you can go together. Make it a family game to see how many single trips you can avoid by combining needs to get to specific places.
