Launching M3O Carbon

Today we’re announcing M3O Carbon, a way to purchase carbon offsets programmatically.

To get started just head to M3O, signup and check out the Carbon service.

Carbon API

Climate change is an important issue and one that the world has finally started to focus on. We all have a responsibility to help offset our carbon emissions and part of that as a company is not only to contribute to it directly but to also enable others to do the same.

Here’s a quick rundown of how to use it

Purchase Carbon Offsets

You can currently purchase 1KG (or 0.001 tonnes) of carbon offsets in a single request.

curl "" \
    -H "Content-Type: application/json" \
    -H "Authorization: Bearer $M3O_API_TOKEN" \
    -d '{}'

And the response should look something like this

    "units": 1,
    "metric": "KG",
    "tonnes": 0.001,
    "projects": [
            "name": "Producing electricity from wind power in Northeast Thailand",
            "percentage": 98,
            "tonnes": 0.00098
            "name": "Wind power generation in Bac Lieu Province, Vietnam",
            "percentage": 2,
            "tonnes": 0.0002

Call the API as many times as you need to purchase the amount of offsets required. The endpoint is currently priced at $0.01 per request.

And that’s it. Signup for free at or join the community on Discord to learn more.
