Overview
Climatiq is an API for calculating carbon emissions and environmental footprint across a wide range of activities including travel, energy use, and shipping. It provides scientifically-backed emission factors sourced from global databases, making it easy to integrate carbon accounting into any application. Beginners can start calculating CO2 equivalents with a single POST request.
Beginner Tip
You need a free API key from climatiq.io to get started. The main endpoint accepts an activity ID and parameters to return CO2e in kilograms — check the emission factor library in their docs to find the right activity ID for your use case.
