Cambridge PACT

Permanent Additional Carbon Tonnes

Calculating the value of natural carbon storage equivalent to a geologically stored (permanent) tonne.

PACT offers a direct comparison between different types of carbon credits with a new framework to demonstrate the long-term carbon value and additionality of nature-based solutions like forest preservation and reforestation.

The climate benefit behind a single PACT is equivalent to a tonne of CO₂ emitted into the atmosphere, accounting for the impermanence of nature-based carbon storage, and with a provable ‘additional’ impact on carbon emissions.

Backed by Cambridge University research, conservation scientists have developed a new understanding of the true carbon storage value of natural environments like forests; computer scientists bring automation and scale to verification using remote sensing and machine learning.
