Frequently Asked Questions
How is CO2 emissions from gasoline calculated?
Burning one gallon of gasoline produces approximately 19.6 pounds of CO2, a standard EPA conversion factor used to estimate vehicle emissions from fuel consumption.
Does carpooling actually reduce my carbon footprint?
Yes, splitting a commute among more passengers divides the total emissions per trip across more people, lowering each individual's share significantly.
How can I reduce my commute emissions?
Options include carpooling, using public transit, switching to a more fuel-efficient or electric vehicle, working remotely more often, or biking for shorter distances.
