In one year the average car puts over 5 tons of Carbon Dioxide into the air. Now you can decrease your carbon footprint. How? With a tree! Just test-drive or purchase a Volkswagen at Carter and we'll plant a tree in your name in the Mountains to Sound Greenway, the scenic byway along the I-90 corridor stretching from Seattle over Snoqualmie Pass into Central Washington. Together we can make a difference and be on the road to Carbon Neutral!. Read more about our Carbon Neutral Program to get a basic understanding of "Planting A Forest, One Test Drive at a Time".
