Carbon Stock Estimator
Estimate carbon stock for any location by analyzing 5 carbon pools: above-ground biomass (AGB — trunks, branches, leaves), below-ground biomass (BGB — root systems), soil organic carbon (SOC — decomposed organic matter), litter (fallen leaves and surface organic matter), and deadwood (fallen trunks and decomposing branches). Select a land use type (forest, cropland, grassland, wetland, urban, other) to calibrate the estimation model. Results show the total carbon stock in tCO₂/ha with a 5-tier classification (Very Low to Very High), annual sequestration rate, and percentage contribution of each pool. The stacked bar chart visualizes the relative composition of each carbon pool. Individual pool result cards display values, units, and share-of-total percentages with color-coded level indicators. Share your analysis with colleagues via link at no additional credit cost and download results as PNG images.
Who Uses This Tool
Professionals who rely on this analysis
Environmental Consultant
Estimate carbon stock at project sites for Environmental Impact Assessments and carbon offset feasibility studies. Compare pools across land use types to evaluate sequestration potential of restoration interventions.
ESG / Sustainability Manager
Quantify carbon stored across corporate landholdings and supply chain sites for CSRD/ESRS E1 climate reporting. Use sequestration rates to model nature-based removal strategies.
Forestry / Land Manager
Assess carbon stock distribution in managed forests and agricultural land. Use pool-level breakdowns to plan harvesting, reforestation, and soil management practices that maximize carbon retention.

Data Sources & Methodology
Carbon stock estimation follows IPCC Tier 1 methodology, using default emission factors and stock values by land use category. Pool-level estimates are calibrated with European forest inventory data and Copernicus land cover classification.
Frequently Asked Questions
Answers to the most common questions about this tool
1What is the Carbon Stock Estimator and what does it analyze?
It is a carbon stock estimation tool. Enter any address and select a land use type to estimate carbon stored in 5 pools: above-ground biomass (AGB — trunks, branches, leaves), below-ground biomass (BGB — root systems), soil organic carbon (SOC — decomposed organic matter in soil layers), litter (fallen leaves and surface organic matter), and deadwood (fallen trunks and decomposing branches). Results include total stock in tCO₂/ha, annual sequestration rate, and pool distribution.
2What are the 5 carbon pools?
Carbon is stored in 5 distinct pools: AGB (above-ground biomass) includes all living plant material above the soil surface. BGB (below-ground biomass) covers root systems and underground structures. SOC (soil organic carbon) represents decomposed organic matter in soil layers — often the largest pool. Litter includes recently fallen leaves, twigs, and surface organic matter. Deadwood covers fallen trunks, stumps, and decomposing branches. Together they represent the complete terrestrial carbon picture.
3How does land use type affect the estimation?
Land use type significantly changes carbon stock distribution. Forests have the highest total stock (especially in AGB and SOC), while croplands store much less above-ground but still hold significant soil carbon. Wetlands can have extremely high SOC values. Urban areas have the lowest overall stock. The tool uses IPCC-aligned default values for each pool-land use combination, calibrated to provide realistic estimates.
4What is the stock level classification?
Total carbon stock is classified on a 5-tier scale: Very High (200+ tCO₂/ha), High (100-199), Moderate (50-99), Low (20-49), and Very Low (0-19). Each level is color-coded from green (high) to orange (low). This classification helps you quickly assess whether a location is a significant carbon sink or has low carbon storage capacity.
5What is the annual sequestration rate?
The annual sequestration rate represents how much additional carbon the location captures per hectare per year, expressed in tCO₂/ha/year. Rates vary by land use: wetlands have the highest rates (typically ~18.6 tCO₂/ha/yr), followed by forests (~8.5), grasslands (~3.8), and croplands (~2.1). This metric indicates the ongoing carbon capture potential of the area.
6Can I share my analysis with colleagues?
Yes. Each completed analysis generates a share link you can send to anyone. Recipients can view the full results — total stock, sequestration rate, pool breakdown, and stacked bar chart — at no credit cost. This makes it easy to collaborate on carbon assessments and sustainability reports.
7What data sources are used for carbon estimation?
Carbon stock estimates are based on IPCC Guidelines for National Greenhouse Gas Inventories, which provide default carbon stock values by land use category and climate zone. The tool combines these with Copernicus land cover data to identify the predominant land use at the selected location. Pool-specific values are calibrated against peer-reviewed literature and national forest inventories.
8How much does a carbon stock analysis cost?
Each carbon stock analysis costs credits based on the number of pools selected. On signup you receive 10 free credits with no credit card required. Additional credit packages start from €19.90. Shared analysis links are free for recipients.
