Ecoia AI vs GreenPT
GreenPT positions itself around sustainable AI with CO2 and energy insights. Ecoia takes measurement further: it tracks carbon, water and energy for every request across chat, images and an API, then offsets more than 200% of that footprint.

What GreenPT focuses on
GreenPT positions itself around sustainable AI, with an emphasis on surfacing CO2 and energy insight for AI usage. For current details on its models, pricing and offsetting approach, it is best to check GreenPT’s own site.
Where Ecoia is different
Ecoia measures carbon, water and energy per request across chat, images and the API, offsets more than 200% of that footprint, commits 10% of revenue to conservation, and exports the data for CSRD and SB-253 reporting.
How they differ
GreenPT positions itself around sustainable AI with CO2 and energy insights, which shares the same starting point as Ecoia: the belief that AI’s footprint should be visible rather than hidden. We don’t have verified current details on GreenPT’s exact features, pricing or offsetting, so the fairest approach is to lay out what Ecoia does and let you confirm the rest on each provider’s site.
Ecoia’s emphasis is end-to-end measurement and action. It estimates the carbon, water and energy of each individual request, not just carbon and not just once a year, then retires verified offsets for more than 200% of that footprint. Including water is a deliberate choice, since AI’s water use is frequently left out of the conversation. Ten percent of revenue also funds conservation, making usage carbon-negative.
Beyond insight, Ecoia is a working platform: the frontier models you already use, image generation, and an OpenAI-compatible API that returns emissions data on every response, with exports formatted for CSRD and SB-253. If you want CO2 insight on your AI, both speak to that; if you want measured, offset and audit-ready AI across chat, images and code, that is Ecoia.
Ecoia vs GreenPT FAQ
What is the difference between Ecoia AI and GreenPT?
GreenPT positions itself around sustainable AI with CO2 and energy insights. Ecoia is a full AI platform: chat with Claude, GPT and Gemini, image generation, and an OpenAI-compatible API, with per-request carbon, water and energy tracking and offsets of more than 200% of the measured footprint.
Do both show the carbon of AI usage?
Surfacing CO2 and energy insight is central to GreenPT’s positioning, and measurement is also Ecoia’s core. Ecoia tracks carbon, water and energy per request across chat, images and the API, then retires verified offsets for more than 200% of that footprint. For GreenPT’s exact metrics, check their site.
Which one offers a developer API?
Ecoia ships an OpenAI-compatible API that returns emissions data on every response, so developers can adopt it with about one line of code. If an API is important to your stack, confirm GreenPT’s current offering directly, since it is a core part of Ecoia.
Does Ecoia track water as well as carbon?
Yes. Ecoia tracks carbon, water and energy per request, not carbon alone, and includes water-use factors in its methodology. Water is often overlooked in AI sustainability, so it is part of what sets Ecoia apart.
How much does Ecoia cost?
Ecoia starts at $20/month for chat and image generation, with per-token API pricing for developers. Every plan funds offsets and conservation.
