Basically everything that we as humans do has an impact on the environment and this can be termed as our Carbon Footprint.Each time we use a car, train, airplane we release carbon dioxide into the atmosphere as these machines burn fuels that release CO2. Using electricity has the same effect as fossil fuels are burnt to generate electricity. The calculator below shows exactly how much CO2 you emit and where you can lower your carbon footprint.
