AI usage CO₂

Live

I used about 3.4 billion tokens over July and part of August, and wanted to know what that costs in CO₂. So I built a small, free tool that estimates it from your Claude Code logs or your ChatGPT export, right in your browser, without installing anything.

Open the tool Source on GitHub

What it does
Reads	Your Claude Code logs (through a short prompt you paste into Claude Code) or your ChatGPT data export
Shows	Tokens by model and type, and CO₂ as a low, middle and high estimate
Explains	Every assumption behind the estimate, with its source
Suggests	Ways to cut your footprint first. If you also want to give money, three ways to contribute to climate work.
Runs	Entirely in your browser. Your files are never uploaded.
Licence	Free and open source (MIT)

ai-co2 result: 13–156 kg CO₂e from Claude Code in the last 30 days, a middle estimate of 40 kg, like driving 250 km, drawn as a row of dots along a kg scale — Fig. 1 The estimate as a range. Each dot is one likely outcome, so you can see how sure it is.

Two ways to cut: moving half of the Opus work to Sonnet, and a third less re-reading, each with the kilograms it saves and a switch to apply it — Fig. 2 Ways to cut. Each tip says how to do it and what it saves. One switch applies it to the estimate.

thesis-kit

Live

A Cursor workspace for writing a thesis from sources you checked yourself. You open the folder, and it finds papers, checks them, and drafts one section at a time. It only cites papers you have opened and confirmed.

Get it on GitHub Read the full entry

What it does
Opens	You clone the repository and open the folder in Cursor. No coding.
Checks	Every paper against Crossref and DataCite. It can be cited only after you confirm you read it.
Drafts	One section at a time, from those papers. Anything it cannot back up is marked [CHECK].
Hands off	A Word file you keep editing, then supervisor comments brought back in as a list.
Records	An optional log of what the AI did, which becomes your AI declaration.
Licence	Free and open source (MIT)

A note from the compiler

I'm Manuel. I build things on the side, partly as a creative outlet, partly because I need to be making something. This is where they live: small, careful tools that show people something about themselves they'd otherwise miss and can be useful to them.

Three entries so far. More as they ship.
