Carbon Footprint Calculator

Estimate your annual CO2 emissions and environmental impact

FAQs

What is a carbon footprint?

A carbon footprint is the total amount of greenhouse gases (including methane and carbon dioxide) that are generated by our actions.

What is the average person's carbon footprint?

The average global carbon footprint is about 4.7 tons per year. In the United States, the average is much higher at approximately 16 tons.

How can I reduce my carbon footprint?

Switching to renewable energy, reducing meat consumption, flying less, and using public transportation or electric vehicles are among the most effective ways to lower your emissions.

How to Use the Carbon Footprint Calculator

Estimate your personal annual greenhouse gas emissions. This comprehensive tool looks at your transportation, home energy, and lifestyle habits.

  1. Enter your annual driving distance and your vehicle's fuel efficiency.
  2. Add your public transit usage and number of flights per year.
  3. Review your home utility bills to input monthly average electricity, gas, or heating oil usage.
  4. Select your diet type (e.g., meat-heavy, vegetarian, or vegan).
  5. Choose your shopping/consumption habits.
  6. See your total annual CO2 tonnage and how it compares to benchmarks.

How Carbon Footprints Help

Measuring your footprint is the first step toward environmental stewardship.

Personal Climate Goals

Establish a baseline for your annual emissions to track reduction progress over time.

Example: Aiming to reduce a 15-ton footprint to 12 tons within a year

Lifestyle Comparisons

Evaluate the impact of major lifestyle changes, like going vegetarian or selling a car.

Example: See if switching to a vegan diet offsets a long-distance flight

Educational Tool

Teach students or family members about the relative impact of daily choices.

Example: Comparing the footprint of a monthly electric bill vs. a cross-country drive

Ways to Lower Your Footprint

Tips

  • Transportation: Walk, bike, or take public transit for short trips. Switch to an EV for longer ones.
  • Energy: Improve home insulation and switch to LED lighting to reduce electricity waste.
  • Diet: Reducing meat consumption, especially beef and lamb, has a massive impact on personal emissions.
  • Consumption: Buy second-hand, repair items instead of replacing them, and avoid fast fashion.
  • Waste: Compost organic waste to reduce methane emissions from landfills.
