Carbon Footprint Calculator

Estimate your annual CO2 emissions from travel, energy, and diet.

Carbon Footprint Calculator Overview

Inputs:
  • Car Miles Driven Per Year
  • Annual Electricity Use (kWh)
  • Diet Type
Output:

Your estimated annual CO2 emissions in tons.

Formula:

Total CO2 = (Car Miles × Emission Factor) + (Electricity × Emission Factor) + Diet Emission

Uses average U.S. emission factors for simplicity.

Understanding Your Carbon Footprint

What is a Carbon Footprint?

Your carbon footprint is the sum of CO2 emissions from your lifestyle choices. Major contributors include transportation, energy consumption, and food production.

  • Car Travel: ~0.4 kg CO2 per mile
  • Electricity: ~0.5 kg CO2 per kWh (U.S. average)
  • Diet: Varies from 1-3 tons/year

Why It Matters

Lowering your footprint reduces your environmental impact. Compare it with our Fuel Cost Calculator for greener travel options.

Frequently Asked Questions

Your carbon footprint is the total greenhouse gas emissions (measured in CO2 equivalent) caused by your activities, like driving or using electricity.

This calculator uses average emission factors for car travel, electricity, and diet to estimate your annual CO2 output.

Reducing your carbon footprint helps combat climate change and promotes sustainability.

The global average is about 4 tons per person per year. Aiming below that is a sustainable goal.

Drive less, use renewable energy, and eat less meat to lower your emissions.
