Carbon Reduction Impact Calculator

It estimates annual CO₂e savings from a climate project using simple activity-based assumptions, then translates the impact into relatable real-world equivalents like cars off the road or homes powered.

CO₂e (carbon dioxide equivalent) is a standard unit that expresses the climate impact of different greenhouse gases in terms of the amount of CO₂ that would cause the same warming effect.

Savings are calculated as activity size multiplied by an emissions factor. For electricity-based projects, this depends on the selected geography’s grid emissions factor.

These represent a reasonable range around the estimate to account for uncertainty in data quality, operational variability, and emissions factors. They are not precise measurements.

Yes. Different countries and regions have different electricity grid emissions. A project saving 1 MWh in a coal-heavy grid avoids more CO₂ than the same project in a renewable-heavy grid.

This tool provides a directional estimate for planning, storytelling, and early reporting. It is not a verified GHG inventory or a substitute for audited carbon accounting.

Equivalences are approximate and based on commonly cited averages. They are designed to make climate impact easier to communicate, not to replace technical reporting.

Yes. The calculator generates a shareable link that preserves your inputs, allowing others to view the same assumptions and results.
