The average person who drives 12,000 miles yearly on under-inflated tires uses about 144 extra gallons of gas, at a cost of $300-$500 a year. And each time one of those gallons of gas is burned, 20 pounds of carbon dioxide is added to the atmosphere as the carbons in the gas are released and combine with the oxygen in the air. As such, any vehicle running on soft tires is contributing as much as 1.5 extra tons (2,880 pounds) of greenhouse gases to the environment annually.

The PSI Project™ is designed to record and measure the reduction of  your carbon emissions as a result of proper tire inflation or PSI (pounds per square inch). By joining The PSI Project™ you acknowledge the impact your vehicle(s) have on our environment and promise to maintain the practical requirements needed to reduce your carbon footprint. Green Dot Environmental will publish your information on our website and add your name to the list existing members.
