Note:

This calculator helps you understand your **carbon footprint**, which is a measure of how much CO2 (carbon dioxide) your activities produce and release into the atmosphere. CO2 is a greenhouse gas that contributes to climate change.

Specifically, this calculator focuses on the **carbon emissions** caused by transportation. When we travel, whether by car, bus, or bike, we use energy that produces CO2. The more we travel, the more CO2 is released.

Here’s how it works:

• Distance Traveled (Miles): The number of miles you travel using a particular mode of transportation. This could be the miles driven in a car, taken by bus, or biked.
• CO2 Emission Factor: This represents the amount of CO2 produced for every mile traveled. Different types of transportation produce different amounts of CO2. For example, a car produces more CO2 per mile than a bike.

CO2 Emission Factors (approximate):

Here are some typical CO2 emission factors for common types of transportation:

Passenger Cars:

• Gasoline car: ~0.411 kg CO2 per mile
• Diesel car: ~0.481 kg CO2 per mile
• Electric car: ~0.2 kg CO2 per mile (depending on the source of electricity)

Public Transport:

• Bus: ~0.13 kg CO2 per mile (per passenger)
• Train: ~0.1 kg CO2 per mile (depending on type)

Air Travel:

• Commercial airplane: ~0.2 kg CO2 per passenger mile

Bicycles and Walking:

• Bicycle: ~0.0 kg CO2 per mile (if human-powered)
• Walking: ~0.0 kg CO2 per mile

By entering how many miles you travel and the type of transportation you use, the calculator will estimate how much CO2 is being released into the air due to your travel.

This **carbon footprint** can help you understand the impact of your travel on the environment and encourage you to make eco-friendly choices, like walking, cycling, or using public transport.
