Six Registry-Aligned Work Packages
Structured to cover every chapter of both Puro.earth 2025 and Isometric EW Protocol — from pre-deployment eligibility through audit submission.
WP0 NEW
Pre-Deployment: Feedstock, Site & Risk
4–6 weeks
Deliverables

Registry Chapter Coverage
Puro.earth: Ch.3 (eligibility), Ch.4 (risk assessment 5-step framework), Ch.3.6 (feedstock characterisation). Isometric: S.4 (applicability), S.5 (environmental & social safeguards), S.8 (feedstock characterisation module).
WP1 EXPANDED

Registry Chapter Coverage
Puro.earth: Ch.11.3 (six quantification approaches, dual-approach mandate), Ch.12 (simulation model guidelines). Isometric: S.7.4.1 (quantification and validation options, soil-based and aqueous-phase methods).
WP3 CORE
DRN Implementation & SMEW Calibration
10–12 weeks
Deliverables
→Implemented DRN model for project river network (documented, version-controlled)

→Calibrated SMEW parameters (dissolution kinetics, transport, retention, losses)
→Preliminary CDR scenario simulations with near-field + far-field contributions
Registry Chapter Coverage
Puro.earth: Ch.6.3 (Closs — river and ocean loss terms), Ch.12 (process-based model requirements). Isometric: S.9.3.5 (watershed/rivers, ocean sections). This is Eartures' core differentiator.

→Emissions accounting formatted for CORC equation and Isometric net CDR calculation
Registry Chapter Coverage
Puro.earth: Ch.7 (project emissions — LCA scope, operational, embodied), Ch.8 (leakage). Isometric: S.7.4.3 (all emissions sub-sections), plus Embodied Emissions, Energy Use, and Transportation modules.
WP5 EXPANDED
Validation & Audit-Ready Package
8–10 weeks
Deliverables
→Model validation against monitoring data, mass balance, and literature ranges
→Uncertainty and sensitivity analyses (weathering rates, partitioning, hydraulic parameters, export fractions)
→Uncertainty discount calculation (Bayesian/frequentist for CORC equation)
→Finalised parameter sets for riverine losses and oceanic uptake
→Registry-specific formatted reports (Puro Ch.13, Isometric Certify templates)
→Clean, annotated scripts (PHREEQC, CO2SYS, SMEW, DRN) with full documentation
→Auditor liaison support (up to 2 audit rounds)
Registry Chapter Coverage
Puro.earth: Ch.10 (uncertainty quantification and discounting), Ch.13 (reporting requirements). Isometric: S.6.2 (verification and validation), S.6.5 (uncertainty reporting), S.9.5 (recordkeeping).
Full programme: 40–52 weeks
WP0 and WP4 can run in parallel with adjacent WPs to compress timeline to ~36 weeks
