About Climatiq

Climatiq provides a developer-friendly API to calculate carbon emissions from any activity—shipping, energy use, cloud computing, travel. It's built for companies that need to embed carbon accounting into their own software.

What it does

You send an activity (e.g., '10 kWh of electricity in Germany') and get back CO2 equivalent emissions. The API uses a constantly updated database of emission factors from scientific sources. It handles complex calculations like supply chain emissions and cloud computing footprints.
