ROCO (Reduction of Carbon Overflow) is a carbon footprint calculator which calculates your emission. Many of our daily activities - such as using electricity, driving a car, or disposing of waste cause greenhouse gas emissions. Together these emissions make up a household's carbon footprint. The calculator estimates your carbon footprint in different sectors: electricity, transportation, food, cooking and waste. Everyone's carbon footprint is different depending on their location, habits, and personal choices. For an accurate estimate, use your own numbers. Gather your utility bills (electricity, natural gas, fuel oil) to calculate your average use over a year and it also provides a graphical representation of your emission. The app provides ways to reduce your carbon footprint and gives a graphical representation of the amount of carbon emission reduced.
