CarbonLint – An open source tool to track local dev carbon emissions 🌍

[nishal21]

Hi everyone,

I’m Nishal, and I’ve been working on an open-source tool called CarbonLint that I thought might be relevant to this group.

The Problem: Most developers have tools to profile CPU and memory for performance, but we rarely see the real-time environmental impact of our local development workflows (builds, test suites, etc.).

The Project: CarbonLint is a desktop application (Electron + React) that monitors system resources and applies regional grid intensity data to estimate the CO2 emissions of your current session.

Why I’m sharing it here: Since this is the Open Source Working Group, I want to ensure this tool is built on solid methodologies and is actually useful to the community.

I’m specifically looking for feedback on: 1. Methodology: How we calculate carbon intensity based on local grid data (currently using a static map approach, looking to move to live APIs). 2. Optimization: I’m using Electron (for cross-platform support), but I am actively working on minimizing the app's own footprint. I'd love advice from anyone with experience in low-power Electron patterns.

The project is fully open source here: https://github.com/nishal21/CarbonLint

If anyone is interested in "Green Ops" tooling or wants to grab a "Good First Issue," I’d love to collaborate!

Thanks, Nishal
