Mangrove

Core Features

Mangrove treats MRV as continuous production accounting: operational and non-operational data flows into a unit-of-output ledger such that commercialization and compliance start from the same traceable dataset. This is measurement- and activity-based accounting built around carbon value chains, not spend-based estimation. Its main features include:

• Unit-of-output carbon ledger — Generates ledger balances per unit of output with traceability and an external-reporting audit trail.

• Program allocation and stackability controls — Allocates inventory to value streams (including 45Q/45Z, LCFS, TIER and voluntary markets) while enforcing stackability and meeting offtake obligations.

• Registry submission workflows — Sends reporting directly to integrated registries and records submission IDs and status (e.g., Isometric, CSI, Verra; more listed as upcoming).

• Mangrove API and data ingestion — Uses the API and other pathways to integrate operational systems and partner/vendor data into Mangrove.

• Partner portals for multi-operator portfolios — Creates managed partner accounts with branded portals for direct MRV data submission, validation feedback and evidence management.

• CCS compliance reporting workflows — Supports automated reporting for tax credits and programs, including EPA Subpart RR/PP and EU ETS compliance management.

Closing Insights

Mangrove Systems was founded to address the challenge of moving carbon projects from manual reporting to a digital, traceable, audit-ready workflow. Its founders and early team brought experience in carbon markets and data systems to build software that ingests diverse operational sources and turns them into a single coherent carbon account for each project. The platform is widely cited for enabling real-time tracking and reporting of CO₂ flows — from capture through transport and storage — for carbon removal (CDR), carbon capture and storage (CCS), renewable natural gas (RNG), and other low-carbon pathways. It integrates operational and non-operational data so developers can continuously monitor performance and prepare verification materials for compliance programs and voluntary registries alike.

Mangrove’s user base includes large project developers such as Carbon Alpha, Accend, and The Carbon Removers, which deploy its MRV system to improve transparency and accelerate credit issuance. It also partners with instrumentation and systems companies (e.g., Endress+Hauser) to enhance measurement fidelity. Its technology is used across North America and in Europe, where regulatory frameworks like the US internal revenue tax credits (e.g. the Section 45Q Tax Credit), California’s LCFS, and EU ETS/CBAM require precise carbon accounting.

For teams responsible for compliance or commercialization of carbon credits, Mangrove offers subscription-based access tailored to operational scale, integrations with existing data sources, and support for registry interfaces.
