About Carbon Footprint Calculation

A carbon footprint calculator helps individuals and organizations measure their impact on the environment by estimating the amount of greenhouse gases (primarily CO₂) produced by their activities.

•How It Works

This calculator uses standard conversion factors to estimate CO₂ emissions from common activities:

–Electricity: 0.92 lbs CO₂ per kWh
–Gasoline: 19.6 lbs CO₂ per gallon
–Natural Gas: 11.7 lbs CO₂ per therm
–Air Travel: 0.4 lbs CO₂ per mile

•Customization Options

The calculator's appearance can be customized using CSS variables:

–--uch-accent: Main accent color
–--uch-bg: Background color
–--uch-text: Text color
