Carbon capture has been measured in tons.
It should be measured in products.

The tectonic shift

Direct-air CO₂ removal cost per ton, 2020–2025 (indexed industry average)

INTRODUCING

Carbon-to-materials:
turning captured CO₂ into building stock

We don't store carbon.
We sell it back as concrete.
