The Science
Every credit begins with a testable hypothesis.
Prithvi CDR's scientific framework is built on the standards of peer-reviewed research — additionality, permanence, measurability, and independent verification. We hold ourselves to what the evidence requires.
Scientific Framework
Additionality
A Prithvi CDR credit represents removal that would not have occurred without our intervention. We establish project-level baselines using historical land use data, satellite analysis, and socioeconomic assessments — and we hold ourselves to conservative additionality assumptions that can survive independent audit.
Permanence
Each pathway is assessed for permanence risk. Biochar and geological-scale removals carry high permanence ratings. Biological removals are managed through long-term legal agreements, buffer pool accounting, and continuous monitoring.
Measurability
We only count what we can measure. Our monitoring protocols use field sampling, laboratory analysis, remote sensing, and third-party verification. Measurement uncertainty is explicitly quantified, and credits are issued conservatively — at the lower bound of the confidence interval.
Leakage Assessment
Restoration in one location can displace harmful activity elsewhere. We conduct project-level leakage assessments and apply deductions where displacement risk is identified — ensuring our net removal claims reflect what actually happened to the atmosphere.
The integrity of a carbon credit is determined not by the price it commands, but by the rigour of the evidence that created it.
Measurement Cycle
Six steps from field to verified credit.
Baseline
Pre-project carbon stocks measured and documented before any intervention.
Intervention
Restoration activities are logged in real time by respective authorities.
Monitoring
Ongoing field sampling and remote sensing at defined intervals per methodology.
Reporting
Standardised monitoring reports prepared and submitted for independent audit.
Verification
Third-party auditor confirms methodology compliance and calculated carbon quantities.
Issuance
Credits are issued to the project registry with a unique identifier, traceable to the verification event.
Verification Standards
Prithvi CDR's methodologies are aligned with internationally recognised carbon standards and undergo independent third-party audit by accredited verification bodies. We publish our monitoring protocols publicly and welcome scientific engagement. The evidence base for each pathway is drawn from peer-reviewed literature — cited in full in our methodology documentation.
Science is not a constraint on our ambition. It is the foundation of our credibility.
