Nova Scotia Mineral OAE Project

Audit Analysis

The Nova Scotia Mineral OAE project is an early-stage ocean alkalinity enhancement project (methodology V1.0) with a 1000-year permanence claim and no reported reversals, but the verification report documents extensive material findings including vanadium exceedances in receiving waters, seabed sediment accumulation, and partial mortality of lobster larvae. No ERR figures (claimed or verified) are available in the extracted record, no buffer pool is stated, and known losses (0.94% sediment, 0.01% calcification) are not included in CDR quantification, creating meaningful over-crediting risk.

Project Description

Red Flags

• ⚠Multiple FEQG exceedances for vanadium in surface waters (5.9 µg/L vs 5 µg/L guideline) with dosing reductions required on two occasions
• ⚠Partial mortality of American lobster larvae at 50 mg/L MgO-2 exposure, indicating ecological risk from the feedstock
• ⚠0.94% potential alkalinity loss to sediments and 0.01% calcification loss explicitly excluded from CDR quantification
• ⚠No buffer pool percentage stated despite a 1000-year permanence claim in a project with active environmental stressors
• ⚠No ERR figures (claimed or verified) found in any available document, preventing any verification of removal claims
