Estimate total carbon sequestration from a reforestation project. Enter hectares, sequestration rate, and project duration to calculate cumulative CO2 removed.
Reforestation — replanting trees on previously forested land — is one of the largest-scale natural climate solutions. Forests sequester approximately 3–15 tonnes of CO2 per hectare per year, depending on climate, species, and stand age. Over decades, reforested land can accumulate hundreds of tonnes of CO2 per hectare.
This Reforestation Carbon Calculator estimates total CO2 sequestered by a planting project. Enter the area in hectares, the average annual sequestration rate, and the project lifetime. The calculator projects cumulative carbon removal.
Project developers, conservation organizations, and carbon credit investors use these estimates for project design, credit issuance, and impact assessment.
Integrating this calculation into regular energy reviews ensures that conservation strategies are grounded in measured data rather than assumptions about building performance and usage patterns. Precise measurement of this value supports sustainable energy planning and helps organizations reduce their environmental impact while maintaining operational performance and comfort levels.
Integrating this calculation into regular energy reviews ensures that conservation strategies are grounded in measured data rather than assumptions about building performance and usage patterns.
Reforestation projects need credible carbon projections for funding, credit issuance, and impact communication. This calculator provides a transparent, adjustable estimate for project planning. Precise quantification supports regulatory compliance and sustainability reporting, ensuring that energy data meets the standards required by auditors and industry certification bodies. Data-driven tracking enables proactive energy management, helping organizations reduce operational costs while progressing toward environmental sustainability goals and carbon reduction targets.
Total CO2 = Hectares × Sequestration Rate (t CO2/ha/yr) × Years.
Result: 24,000 tonnes CO2 sequestered
100 ha × 8 t/ha/yr × 30 years = 24,000 tonnes = 24,000 carbon credits.
The Bonn Challenge aims to restore 350 million hectares of degraded land by 2030. At average sequestration rates, this could remove 1–2 billion tonnes of CO2 per year — about 3–5% of global emissions. While not sufficient alone, it's a meaningful contribution.
Projects typically cost $500–5,000 per hectare for planting, depending on location and species. Carbon credit revenue ($5–30/tonne) can offset some costs. In many cases, reforestation also provides timber, non-timber forest products, and ecosystem service payments.
Remote sensing (satellite imagery, LiDAR), drone surveys, and ground-based sampling enable accurate monitoring of forest growth and carbon stocks. These technologies are improving and becoming more affordable, increasing confidence in reforestation carbon claims.
Rates vary widely: tropical moist forests average 10–15 t CO2/ha/yr, temperate forests 3–8 t/ha/yr, and boreal forests 1–4 t/ha/yr. Fast-growing eucalyptus plantations can exceed 20 t/ha/yr but with biodiversity tradeoffs.
Carbon credits from reforestation typically have 20–40 year accounting periods. However, the carbon remains stored as long as the forest stands. Permanence guarantees usually extend 100 years for crediting programs like Verra VCS.
Fire, pest outbreaks, illegal logging, and climate change impacts (drought, storms) can release stored carbon. Credit programs address this through buffer pools: 10–20% of credits are set aside in a shared insurance pool.
Reforestation replants land that was previously forested. Afforestation plants trees on land that was not recently forested (e.g., degraded agricultural land). Both sequester carbon, but they face different ecological and social considerations.
Yes. Reforestation projects can generate carbon credits under standards like Verra VCS, Gold Standard, and Plan Vivo. Credits require third-party validation, monitoring, and verification. The process typically takes 1–2 years to set up.
This is a linear estimate using average annual rates. In reality, sequestration follows a growth curve: low in early years, peaking at 10–20 years, then declining as forests mature. For detailed project planning, use forestry growth models.
