Personal Carbon Footprint Calculator
Audit your Scope 1, 2, and 3 emissions. Measure impact from energy, travel, and diet.
Your carbon footprint is the total greenhouse gas emissions your household generates in a year, measured in tons of CO2e. It's calculated as Total Emissions = Σ(Activity × Emission Factor) across home electricity, vehicle miles, air travel, and diet.

The GHG Protocol Audit
Reaching Net Zero requires optimizing all three scopes of emissions: direct fuel, purchased energy, and lifecycle impacts.
Emission factors used in this model are aligned with the EPA's Greenhouse Gas Equivalencies Calculator, which publishes its full methodology and data sources.

?What is CO2e?
CO2 equivalent (CO2e) is a metric used to compare the emissions from various greenhouse gases on the basis of their global-warming potential.
?How many trees offset 1 ton?
On average, one mature tree sequesters about 48 pounds of CO2 per year. Roughly 40-50 trees are needed to offset one ton annually.
?Is diet really that impactful?
Yes. Animal agriculture accounts for nearly 15% of global emissions. Switching from heavy meat to plant-based can halve your personal footprint.
