1.  Transportation choices and CO 2 emissions By: Dayanara Veliz & Abel Adam

2. Facts  Car: 2008 Nissan Armada  28 gallons of gas /week  1,456 gallons / year  12.9 metric tons of CO 2 emitted / year  10.6 acres of U.S. forests are needed to sequester this amount of CO 2  This is equivalent to the annual CO 2 emissions of:  2.7 passenger vehicles (20axle, 4 tires)  0.647 homes’ energy use  1.8 homes’ electricity use  30.1 barrels of oil

3. Comparison to overall U.S Data  Average annual CO 2 emissions of a passenger car is 5.1 metric tons (compared to 12.9)  More than half of CO 2 household emissions come from vehicles  Nissan: 14 MPG

4. Solutions  Switching to Minivan: 21 MPG  If you drive 15,000miles a year you save $1200 in gas.  Annually, switching from a 20 MPG vehicle to a 30 MPG vehicle saves you $903 dollars (assuming 15,000 miles of driving).  Filling the gas tank once a week will release 9.2 metric tons a year (already a reduction).  Increase of tax on cars that are inefficient, to cover the cost of CO 2 emission effects.  Tax on gas  more efficient use of cars  Incentives to use public transportation
