How It Works

1.

Look up your product

Search across 523 material and product categories — from smartphones to steel, cotton to cleaning products.

2.

See the default CCI score

Every category shows a conservative carbon estimate in kgCO₂e, with full scope breakdown, emission hotspots, and sourced methodology.

3.

Submit verified data to improve it

Suppliers and brands can override the default with verified EPDs, PCFs, or factory data — turning a conservative estimate into a verified score.
