Blue carbon: coastal ecosystems fighting climate change! Blue carbon = carbon captured by oceans/coasts (mangroves, seagrass, salt marshes). Sequestration power: 40x faster than rainforests per area!

Manage restoration projects: (1) Mangrove reforestation (Vietnam lost 50%+ last 50 years, replant coastal zones), (2) Seagrass meadows (restore degraded areas, protect from trawling), (3) Salt marsh conservation (temperate regions). Carbon accounting: measure biomass (above/below ground), soil organic carbon (meters deep!), growth rates, calculate tCO2 sequestered annually. Methodologies: Verra VCS (Verified Carbon Standard), Plan Vivo, IPCC guidelines.

Verification: field surveys, remote sensing (satellite imagery detect vegetation), core sampling (measure soil carbon), third-party audits. Carbon credits: sell voluntary market ($15-50/tCO2), compliance markets developing. Co-benefits: (1) Coastal protection (storm surge buffer), (2) Fisheries (nursery habitats), (3) Biodiversity (critical ecosystems), (4) Livelihoods (eco-tourism, sustainable fishing).

Challenges: additionality (prove project caused sequestration), permanence (ensure 25+ years not destroyed), leakage (deforestation shifts elsewhere), baseline (what would happen without project?). Real projects: Mikoko Pamoja Kenya (world first blue carbon project), Mekong Delta Vietnam pilots, Sundarbans Bangladesh. Finance: blue bonds (Seychelles $15M), World Bank support.

Vietnam potential: 250K+ hectares mangroves, Mekong Delta restoration critical (climate adaptation + carbon). Nature-based climate solutions!
