About this project

The Climate Impact Visualizer is a small, interactive tool for estimating your personal greenhouse-gas footprint from everyday choices (driving, flying, home energy, food, and shopping) and exploring how changing those choices would affect it.

It's intentionally simple: no account, no backend, no database. Your answers live only in your browser. It doesn't model every possible source of emissions, and it isn't a substitute for a rigorous personal carbon audit. The goal is to make the relative scale of everyday choices tangible and explorable, with every number traced back to a public, reputable source.

See the methodology page for the full list of data sources, assumptions, and known limitations.
