+# Carbon Footprint Calculator
+
+## Summary
+
+This SharePoint Framework (SPFx) web part provides users with an interactive calculator to estimate their monthly carbon footprint.
+
+It helps users visualize their CO₂ emissions through intuitive inputs such as electricity usage, transportation habits, and more.
+
+The solution uses **React**, **Fluent UI**, and **Chart.js** for dynamic charts, and supports exporting results to **PDF**.
+
+![Solution in Action](./assets/sample.png)
+
+## Compatibility
+
+| :warning: Important          |
+|:---------------------------|
+| Every SPFx version is optimally compatible with specific versions of Node.js. In order to be able to build this sample, you need to ensure that the version of Node on your workstation matches one of the versions listed in this section. This sample will not work on a different version of Node.|
+|Refer to <https://aka.ms/spfx-matrix> for more information on SPFx compatibility.   |
+
+This sample is optimally compatible with the following environment configuration:
+
+![SPFx 1.21.1](https://img.shields.io/badge/SPFx-1.21.1-green.svg)
+![Node.js v18](https://img.shields.io/badge/Node.js-v18-green.svg)
+![Compatible with SharePoint Online](https://img.shields.io/badge/SharePoint%20Online-Compatible-green.svg)
+![Does not work with SharePoint 2019](https://img.shields.io/badge/SharePoint%20Server%202019-Incompatible-red.svg "SharePoint Server 2019 requires SPFx 1.4.1 or lower")
+![Does not work with SharePoint 2016 (Feature Pack 2)](https://img.shields.io/badge/SharePoint%20Server%202016%20(Feature%20Pack%202)-Incompatible-red.svg "SharePoint Server 2016 Feature Pack 2 requires SPFx 1.1")
+![Local Workbench Unsupported](https://img.shields.io/badge/Local%20Workbench-Unsupported-red.svg "Local workbench is no longer available as of SPFx 1.13 and above")
+![Hosted Workbench Compatible](https://img.shields.io/badge/Hosted%20Workbench-Compatible-green.svg)
