ChatGPT emits over 260 tonnes of CO₂ a month.

 That's like 500 NYC to London flights.

This guide helps you 
prompt consciously.



1. Use GPT-4o instead of GPT-4
A ➸ Same output, faster results, and much less energy. It’s the most efficient model, and nobody will notice the switch.



2. Keep your prompts short and clear
A ➸ More words mean more processing. Be direct, say what you need, and don’t waste extra energy on fluff.



3. Ask once and reuse what works
A ➸ If a prompt already did the job, use it again. Asking better once is cleaner than prompting five times.



4. Don’t use AI for easy stuff
A ➸ Things like fixing typos or searching Google don’t need an AI model. Some tasks are just easier without the extra compute.




5. Delete content you’re not using
A ➸ Files you forget still sit on servers. Clearing out unused drafts helps reduce unnecessary storage emissions.


About:ChatCO2 began by collecting the 40 most asked questions on ChatGPT. Two things became clear: we’re using a powerful tool for trivial tasks, and we have no idea how much energy that really takes.

As a next step, this guide shares small, practical ways to prompt more consciously. We owe it to our future selves and the planet.

Dear OpenAI,
please don’t sue me.
