Estimate your carbon footprint
Understanding your environmental impact starts with measuring it, and a footprint estimate does that. This calculator estimates your personal CO2e footprint from electricity, gas, transport and other factors.
Why a footprint estimate helps
A carbon footprint sums the greenhouse gas emissions your activities cause, converted to a common measure (CO2e), across the big contributors: home energy, transport, and consumption. Seeing the total, and which parts dominate, turns a vague concern about impact into a concrete picture, which is the basis for reducing it deliberately, targeting the biggest sources rather than the most visible ones. People are often surprised by where their footprint actually comes from, so estimating it is the useful first step toward informed choices about what to change.

Frequently Asked Questions
What is CO2e?
Carbon dioxide equivalent, a common measure that converts different greenhouse gases into a single comparable figure of climate impact.
What does the footprint include?
The big contributors to personal emissions: home energy like electricity and gas, transport, and other consumption, summed into a total.
Why estimate my footprint?
Because seeing the total and which parts dominate turns a vague concern into a concrete picture, the basis for targeting the biggest sources.
Where does a footprint usually come from?
It varies, but home energy and transport are commonly large, and people are often surprised by the actual breakdown, which is why estimating helps.
Is my data uploaded?
No. The calculation runs entirely in your browser.
