[C]Worthy is a nonprofit research organization developing open, scientifically rigorous tools to support ocean-based carbon removal. https://www.cworthy.org/
2025 was a turning point for mCDR. Across OAE and DOC, the field moved from promise to proof: pilots advanced, first verified credits were delivered, and new standards, permits, and infrastructure took shape. We recap some of the year’s key industry milestones here: www.cworthy.org/blog/year-in...
Year in Review: 2025 Marine Carbon Dioxide Removal Milestones — [C]Worthy
A look back at the major milestones that defined mCDR in 2025—from first verified ocean-based carbon dioxide removal credits to new permits, protocols, and growing policy momentum.

Configuring a regional ocean model is time-consuming, error-prone, and hard to reproduce. Our new demo shows how ROMS-Tools streamlines grid design and input file generation for ROMS-MARBL. Watch Nora Loose, PhD, walk through the workflow and its value for mCDR MRV. www.cworthy.org/blog/a-roms-...
A ROMS-Tools Deep Dive — [C]Worthy
Our latest technical demo highlights ROMS-Tools, a Python package that provides user-friendly tools to design new regional grids for ROMS-MARBL and streamlines the creation of the input files necessar...

Trust in mCDR depends on transparent, reproducible ocean models—but today they’re hard to interpret or audit. Our new blog explains how C-Star and C-Star Blueprints will help build the integrity infrastructure the field needs. Read more: www.cworthy.org/blog/buildin...
Building the Integrity Infrastructure for mCDR Modeling — [C]Worthy
To build trust in mCDR, the calculations that underpin carbon crediting need to be transparent and reproducible. This piece introduces the C-Star Blueprint: a new tool that makes ocean models auditabl...
