Delivering the very best of CDR credits
CDR = Carbon Dioxide Removal
Being technology-based, biochar CDR delivers much stronger guarantees on the stability of carbon stored. Where traditional nature-based solutions offer permanence of a few decades, biochar CDR extends this to millennia.
This aligns with the recommendations of IPCC, SBTi, and other leading standards. Since CO₂ itself persists in the atmosphere for centuries, only high-permanence CDR offers true like-for-like compensation of emissions.
As the leading high-permanence CDR solution available today, biochar is uniquely positioned to deliver climate impact at scale. NetZero's integrated, end-to-end approach to biochar production enables us to offer our clients the very best high-permanence CDR credits.
Using only the highest-integrity standards
The Puro Standard is the world's leading certification programme for engineered carbon removal projects. Its biochar methodology is trusted by all the largest CDR credit buyers, applies conservative accounting rules, and builds on hundreds of certified projects. NetZero has actively contributed to improving the methodology with practical learnings from its own projects.
Puro's biochar methodology
The Isometric Standard is a more recent certification programme built around the latest biochar science for carbon removal. It notably leverages random reflectance to measure inertinite — the most precise way to determine biochar's carbon stability over time. The standard is highly data-driven, with robust MRV requirements, and is already used by some of the largest CDR credit buyers.
Isometric's biochar protocol
Maximum flexibility, minimal risk
Transaction type
From spot purchases to long-term off-take agreements, we tailor delivery to your needs — against a fixed schedule, or with flexible call-down volumes.
Volume flexibility
Contracts can include annual step-up or step-down options, giving you room to adjust as your decarbonisation roadmap evolves.
Optionality
Forward contracts can include cancellation windows and vintage-selection rights — retaining your flexibility without forfeiting supply priority.
Multi-site diversification
Credits are sourced from multiple production sites across Brazil. Multi-origin contracts distribute delivery risk and eliminate single-project exposure.
