Delivering the very best of CDR credits
CDR = Carbon Dioxide Removal
Carbon dioxide removal (CDR) captures CO₂ already present in the atmosphere and stores it permanently — going beyond emission reduction to actively reverse accumulated damage. It is a necessary complement to deep decarbonisation, not a substitute for it.
NetZero produces biochar CDR credits with 1,000+ year storage permanence, generated from agricultural residues in Brazil. Each credit is traceable, independently verified, and backed by robust science — no proxy accounting, no rounding up.
Using only the highest-integrity standards
Puro Standard is the world's leading certification programme for engineered carbon removal projects. Its biochar methodology — built on thousands of peer-reviewed scientific publications — covers the full value chain: feedstock sourcing, production process, biochar application, and permanence accounting. NetZero's credits are issued on the Puro registry.
Puro's biochar methodology
Isometric is an independent carbon removal verification platform built for scientific rigour. It conducts its own technical reviews of CDR methodologies and issues certifications based solely on physical evidence — no modelling shortcuts, no estimates where direct measurement is possible. NetZero's projects are verified by Isometric.

Maximum flexibility, minimal risk
Contract structure
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.
