A car carbon footprint calculator is a tool that calculates the CO2 emissions produced by a car. It aims to provide a clear and accurate picture of the environmental impact of driving, both for individuals and organizations. This includes the emissions produced globally by cars. With the information provided by the calculator, users can take steps to reduce their carbon footprint and minimize their impact on the planet by driving less or choosing more eco-friendly vehicles.

​

​To use a car carbon footprint calculator, you typically input the number of kilometers you drive and your average fuel consumption per 100 kilometers. The calculator then uses this information, along with data on emissions produced per liter of fuel, to estimate the total CO2 emissions produced by your car. Additionally, the calculator may also include an option to buy NFTs, where 1 NFT equals 1.25 tons of CO2 removed from the atmosphere, as a way to offset the carbon footprint and achieve net zero emissions.
