What is Blue Carbon?

Coastal Forests That
Outperform the Amazon.

Mangrove forests are among the most carbon-dense ecosystems on Earth. Their unique biology — growing at the intersection of land and sea — allows them to sequester carbon in both above-ground biomass and, critically, in the anoxic sediments below, where organic matter is preserved rather than decomposed. This "blue carbon" can accumulate for thousands of years, making mangroves exceptionally valuable as long-term carbon stores.

Per hectare, mangroves can sequester 10–30 tCO₂e annually — up to 5× the rate of tropical forests — while delivering irreplaceable services for coastal communities: protecting shorelines from storm surge and erosion, providing nursery habitat for commercially important fish species, and sustaining the livelihoods of fishing families who depend on healthy coastal ecosystems.

Vivent Carbon restores degraded and deforested mangrove areas across Indonesia, Philippines, Vietnam, Bangladesh, and Myanmar — working with coastal fishing cooperatives, indigenous communities, and local government to co-design restoration schemes that genuinely serve community needs alongside carbon goals.

How It Works

From Degraded Coast
to Thriving Blue Carbon Sink

Mangrove restoration is more than planting — it starts with restoring the tidal hydrology that allows mangroves to survive and thrive.

1
🗺️
Site Assessment

Remote sensing and field surveys identify degraded mangrove areas, assess historical coverage, tidal flow, sediment condition, and salinity to determine restoration feasibility and methodology.

2
🤝
Community Partnership & FPIC

Fishing cooperatives and coastal communities are primary project partners — not just beneficiaries. FPIC agreements signed, sea-use rights documented, and community management committees formed.

3
🌊
Hydrological Restoration

Before any planting, blocked tidal channels are reopened and earthen bunds removed. Restoring tidal flow is the single most important factor for mangrove survival and carbon accumulation in sediments.

4
🌱
Community Nurseries & Planting

Community nurseries propagate native Rhizophora, Avicennia, and Sonneratia species. Planting follows seasonal tidal windows. Community members paid as restoration workers throughout.

5
📡
MRV — Above & Below Ground

Canopy cover tracked quarterly via Sentinel-2 and drone imagery. Sediment carbon cores taken annually to measure below-ground blue carbon accumulation — often the larger carbon pool in mangroves.

6
Verification & Credit Issuance

Third-party verification under VCS VM0033 every 5 years. Credits issued for both above-ground biomass and sediment carbon, capturing the full value of blue carbon sequestration.

Integrated Fishery Management

Community-managed fishery zones established within restored mangroves. Revenue from sustainable harvesting supplements carbon income and creates incentives for long-term stewardship.

💰
Revenue Distribution

≥68% of carbon credit revenue paid to community management committees within 30 days of credit settlement. Fishery revenue distributed monthly via cooperative structures already in place.

Beyond Carbon

Why Mangroves Are
Nature's Swiss Army Knife

No other ecosystem delivers this many ecosystem services simultaneously — making mangrove credits highly attractive for buyers seeking co-benefit richness.

🛡️
Coastal Storm Protection

A 100m belt of mangrove forest can reduce wave height by 13–66%, protecting coastal communities from storm surge, flooding, and erosion — a benefit that grows as sea levels rise. SDGs: 13, 11.

SDG 13SDG 11
🐟
Fisheries & Food Security

Mangroves serve as nursery habitat for 75% of tropical commercial fish species. Communities within restored mangrove zones report 30–50% increases in nearshore fish catch within 3–5 years.

SDG 2SDG 14
🦀
Biodiversity & Marine Life

Restored mangroves support 341+ fish species, dugongs, sea turtles, and critically endangered shorebirds. Sediment stabilisation prevents coral reef siltation downstream of project sites.

SDG 15SDG 14
👩‍👧
Women's Livelihoods

Mangrove-dependent activities — shellfish collection, crab aquaculture, and nursery propagation — are primarily led by women. Vivent's programmes increase women's economic participation by an average 28%.

SDG 5SDG 1
💰
Diversified Community Income

Carbon credits, sustainable fisheries, eco-tourism, and mangrove honey production create 4+ independent income streams for participating communities, significantly reducing economic vulnerability.

SDG 8SDG 10

Water Quality

Mangrove root systems filter terrestrial runoff, removing nitrogen, phosphorus, and heavy metals before they reach coral reefs and seagrass meadows — protecting downstream marine ecosystems.

Where We Work

Mangrove Restoration Across
Five Indo-Pacific Nations

Southeast Asia holds 33% of the world's remaining mangrove forests — and has lost more than any other region. Vivent focuses here because the restoration potential is highest.

Field ReportNorth Sulawesi, IndonesiaYear 4 Results

Manado Bay: 40% Higher Survival Rates Through Community-Led Restoration

Vivent's North Sulawesi programme enrolled 42 fishing villages across Manado Bay in 2021. Rather than contracting external planting crews, the programme trained and employed 1,200 community members as restoration workers — propagating native Rhizophora apiculata and Avicennia marina in 28 community nurseries before planting across 3,800 ha of degraded inter-tidal zones.

Four-year monitoring shows a survival rate of 82% — 40% higher than government-managed restoration sites in the same region that used contracted crews with no community involvement. Communities also report a 44% increase in nearshore fish catch from the restored mangrove nursery zones, adding an estimated $180 per household annually in additional fishery income on top of carbon revenues.

Common Questions

Mangrove Carbon Credits — FAQ

Mangrove credits issued under VCS VM0033 with CCB Gold certification are widely considered among the highest-quality nature-based credits available. The methodology requires rigorous accounting of both above-ground and below-ground carbon, uses conservative baselines, and mandates community benefit monitoring. Vivent's credits include full FPIC documentation and social impact data, meeting ICVCM Core Carbon Principles requirements.
Restoration projects plant in areas where mangroves have been lost, generating removal credits for new carbon sequestration. Conservation (REDD+) projects protect existing mangroves from deforestation, generating avoided-emission credits. Vivent primarily focuses on restoration, which generates genuine carbon removal rather than avoided emissions. Both have value — we recommend buyers consider both types in a balanced portfolio.
Paradoxically, healthy mangroves are highly resilient to sea level rise — sediment accretion rates in productive mangroves typically match or exceed projected sea level rise rates for this century. However, degraded or isolated mangroves with blocked tidal flow can be vulnerable. Vivent's projects prioritise tidal reconnection as a first step precisely to give restored mangroves the hydrological resilience to track sea level rise over the crediting period. All projects model sea level scenarios in permanence risk assessments.
Leakage is a key quality indicator for all Vivent projects. In mangrove programmes, leakage risk comes primarily from shrimp farming — protecting one area could push aquaculture expansion elsewhere. We address this by working with government fisheries authorities to enforce coastal zoning, and by ensuring community-managed sustainable aquaculture zones are part of every project design, reducing the economic pressure to expand into new areas.
